Executive Summary

Spain regulates the industrial — welder trade through a layered statutory framework comprising the host-state Labour Code, the labour-migration statute, the spatial-development or construction-categorisation act, and EU-derived regulations transposed under accession treaty obligations. Cross-border deployment of industrial — welders into Spain sites engages four concurrent regulatory layers: immigration authorisation, labour-migration registration with the host inspectorate, social-insurance affiliation under EU Regulation 883/2004, and firm-level construction qualification.

Industrial — Welder as a stand-alone occupation in Spain sits within the broader construction sector regulatory framework. Trade-specific recognition pathways operate under the Recognition of Professional Qualifications regime transposing Directive 2005/36/EC as amended by 2013/55/EU. pressure-equipment and structural welding to EN ISO 9606 on multi-trade sites adds firm-level construction-qualification overhead and may engage trade-adjacent regulated activities such as welding (EN ISO 9606), lifting equipment operation, and pressure-equipment work depending on the site context.

Bottom line: Spain is a Tier-1 wage destination for industrial — welder deployment. Total deployment cost reflects high statutory minimum wage, sector-fund contributions where applicable, and qualification-recognition lead times. Pre-deployment compliance preparation reduces exposure to inspectorate-driven schedule disruption.

Spain is a civil-law jurisdiction under the Constitución Española of 27 December 1978, with competence distributed between the Estado central and seventeen Comunidades Autónomas plus Ceuta and Melilla. Labour law, immigration, social security, and construction-subcontracting regulation are reserved to the State under Article 149.1.2ª, 149.1.7ª, and 149.1.17ª of the Constitution; autonomous communities legislate complementary norms in occupational health and safety, vocational training, and sector certification (notably Cataluña, País Vasco, Madrid, Andalucía, and Valencia maintain dense local registries). Spain has been an EU member since 1 January 1986 (Treaty of Accession of 12 June 1985) and applies the full EU labour-mobility, posted-worker, and qualifications-recognition acquis. Three reform vectors define the current landscape for non-EU workforce deployment: (1) the Reforma Laboral introduced by Real Decreto-ley 32/2021, de 28 de diciembre (BOE núm. 313, de 30/12/2021), which restructured fixed-term contracting and preserved the construction-sector contrato fijo de obra under disposición adicional tercera; (2) the Ley Orgánica 4/2000, de 11 de enero, sobre derechos y libertades de los extranjeros (LOEx), as developed by Real Decreto 1155/2024, de 19 de noviembre (BOE núm. 280, de 20/11/2024), in force since 20 May 2025, which restructured residence-and-work pathways and consolidated the figura del arraigo; (3) the Estatuto de los Trabajadores in its consolidated form under Real Decreto Legislativo 2/2015, de 23 de octubre (BOE núm. 255, de 24/10/2015), the master labour code. Primary statutes accessible at https://www.boe.es/.

Trade-specific context

The industrial welder performs joining of metallic materials by fusion welding processes for industrial plant, structural steel, and process-piping applications. The role spans three distinct operational categories.

Structural welding covers carbon steel (S235 to S460), low-alloy and stainless steels in load-bearing applications under EN 1090-2 (https://www.iso.org/standard/65977.html for the source EN ISO 9606-1 referenced therein) — bridges, frames, towers, offshore jackets, gigafactory steelwork. Process-piping welding covers pressurised systems under PED 2014/68/EU (https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32014L0068) and EN 13480 — refinery flowlines, steam headers, hydrogen lines — typically TIG (GTAW, ISO process 141) for the root pass on stainless and alloy, with MIG/MAG (GMAW, 135), FCAW (136) or SMAW/MMA (111) for fill and cap. Specialist welding includes orbital TIG for repeatable small-bore pipework (semiconductor and pharmaceutical clean utilities), submerged-arc (SAW, 121) for heavy section, pulsed-MIG for thin stainless and aluminium, and TIG for nickel alloys (Inconel 625/825) and duplex/super-duplex used in subsea and chemical service.

The industrial welder is distinct from the sheet-metal worker (lower amperage, ducting and ventilation, often gas-shielded MIG only), from the structural fitter (cut, bevel, tack, fit-up — but no production welding scope), and from the welding operator under EN ISO 14732, who runs mechanised or fully automatic equipment rather than performing manual fusion welding.

Regulatory Bodies

Industry-Specific Compliance Stack

For industrial — welder deployment to a Spain site, the four-layer compliance stack — immigration authorisation, posting notification, social-insurance affiliation, and firm-level qualification — operates concurrently. Failure on any single layer can trigger inspectorate enforcement.

Spain is a civil-law jurisdiction under the Constitución Española of 27 December 1978, with competence distributed between the Estado central and seventeen Comunidades Autónomas plus Ceuta and Melilla. Labour law, immigration, social security, and construction-subcontracting regulation are reserved to the State under Article 149.1.2ª, 149.1.7ª, and 149.1.17ª of the Constitution; autonomous communities legislate complementary norms in occupational health and safety, vocational training, and sector certification (notably Cataluña, País Vasco, Madrid, Andalucía, and Valencia maintain dense local registries).

3. Professional Recognition & Certification

Industrial — Welder as a stand-alone occupation in Spain typically does not carry an individual ordinal-registration requirement, though some host states (notably Germany under HwO Anlage A) impose Meisterzwang or equivalent qualification gates for specific construction trades. The Recognition of Professional Qualifications regime transposes Directive 2005/36/EC as amended by 2013/55/EU.

For EEA-issued industrial — welder certificates, recognition flows under the automatic or general systems with typical processing of 2-6 weeks. For non-EEA certificates, equivalence assessment by the host-state competent authority typically runs 4-12 weeks and may require supplementary assessment via a designated host-state VET centre.

Spanish construction-sector restrictions operate through three interlocking instruments: (a) the Tarjeta Profesional de la Construcción (TPC), (b) the Registro de Empresas Acreditadas (REA), and (c) trade-specific qualifications.

  • Tarjeta Profesional de la Construcción (TPC): Mandatory for all workers on Spanish sites under the VII Convenio General Estatal de la Construcción 2023-2027 (Resolución de 23 de mayo de 2023, BOE núm. 134, de 6/6/2023). Issued by the Fundación Laboral de la Construcción (FLC) at https://www.trabajoenconstruccion.com/ following mandatory PRL training (20 h initial Aula Permanente plus trade-specific second-cycle hours: 20 h for albañiles, encofradores, ferrallistas, fontaneros, soldadores, operadores de grúa; 6 h for electricistas). Issuance cost approximately EUR 21 plus training-provider fee.

  • Registro de Empresas Acreditadas (REA): Established by Ley 32/2006, de 18 de octubre (BOE núm. 250, de 19/10/2006), developed by Real Decreto 1109/2007, de 24 de agosto (BOE núm. 204, de 25/8/2007). Every contractor or subcontractor performing construction work must be entered in the REA of its domicile autonomous community; acreditación verifies productive infrastructure, HR capacity, training compliance, and indefinite-contract minima. Foreign EU service providers notify rather than register but must hold an equivalent home-state declaration.

  • Subcontracting chain limit (RD 1109/2007 Art. 5 and Ley 32/2006 Art. 5): The contratista principal may subcontract to first-tier, who may subcontract to second tier, who may subcontract to third tier; the third-tier subcontractor may not further subcontract except for own-labour autónomo work or where exceptional justification is approved by ITSS. The 2023 Plan Director por un Trabajo Digno renewed ITSS targeting of chain infractions.

  • Trade-specific qualifications: Electricians performing baja-tensión installations require the Carné de Instalador Eléctrico (Categoría Básica or Especialista) per Real Decreto 842/2002 (REBT) ITC-BT-03, issued by the autonomous community. Welders for pressure-vessel and structural welding operate under EN ISO 9606-1/3834-2 with company-level certification under RD 709/2015 (Reglamento de Equipos a Presión) and EN 1090-2 for structural steel. Operators of grúa torre and grúa móvil autopropulsada require the Carné de Operador issued under RD 837/2003 and RD 836/2003.

Trade-specific context

The dominant European welder qualification is EN ISO 9606-1: Qualification testing of welders — Fusion welding — Part 1: Steels (https://www.iso.org/standard/63110.html). It defines essential variables — process, plate or pipe, position, base material, filler, thickness, backing, dimensions — that together determine the certificate’s validity range. A welder qualified for 6G position on pipe is automatically qualified for 1G/2G/5G on plate or pipe; the inverse does not hold.

Companion parts cover non-ferrous materials: EN ISO 9606-2 for aluminium and aluminium alloys (https://www.iso.org/standard/35181.html), EN ISO 9606-3 for copper and copper alloys (https://www.iso.org/standard/24062.html), EN ISO 9606-4 for nickel and nickel alloys (https://www.iso.org/standard/24063.html), and EN ISO 9606-5 for titanium, zirconium, and their alloys (https://www.iso.org/standard/26680.html).

EN ISO 14732: Welding personnel — Qualification testing of welding operators and weld setters for mechanized and automatic welding of metallic materials (https://www.iso.org/standard/56871.html) covers the operator scope.

Welding procedure specifications (WPS) — the document a welder works to — are qualified under EN ISO 15614-1 (arc and gas welding of steels and nickel alloys, https://www.iso.org/standard/68796.html) and EN ISO 15614-2 (aluminium alloys, https://www.iso.org/standard/29521.html).

For the 9606 qualification approach itself, EN ISO 15609-1 (https://www.iso.org/standard/72502.html) defines the WPS content. EN ISO 3834 (https://www.iso.org/standard/35144.html) defines the firm-level quality requirements for fusion welding — the company-level certification that a contracted EPC employer will normally hold.

US-specification qualification under ASME Section IX (https://www.asme.org/codes-standards/find-codes-standards/bpvc-ix-bpvc-section-ix-welding-brazing-fusing-qualifications) is widely accepted on US-engineered EPC sites in Europe (refining, petrochemicals, LNG, US-licensed nuclear). It is NOT automatically equivalent to EN ISO 9606; a welder needs both certificates if working across both standard regimes.

Country-specific supplementary schemes:

International umbrella authority is the International Institute of Welding (IIW, https://iiwelding.org); European is the European Federation for Welding (EWF, https://www.ewf.be). Both operate harmonised diploma routes (IWE/EWE — engineer; IWS/EWS — specialist; IWP/EWP — practitioner; IWIP — inspection personnel).

4. Social Security & Insurance

A1 portable documents are issued by the home-state social-insurance institution under EU Regulation (EC) 883/2004 and accepted by Spain authorities for inbound postings. Absence of a valid A1 triggers Spain social-security liability from day one of work.

Contribution architecture: standard EU host-state pattern of employer + employee contributions on insurable income, typically 25-35% combined depending on trade-specific risk classification and sector-fund supplements where applicable.

Spanish social security is codified in the Texto Refundido de la Ley General de la Seguridad Social, approved by Real Decreto Legislativo 8/2015, de 30 de octubre (BOE núm. 261, de 31/10/2015), at https://www.boe.es/buscar/act.php?id=BOE-A-2015-11724. The system is administered by the Tesorería General de la Seguridad Social (TGSS, https://www.seg-social.es/) under the Ministerio de Inclusión, Seguridad Social y Migraciones.

  • Régimen General: Default regime for employed workers, including construction since 1 January 2012 when the former Régimen Especial de la Construcción was integrated with sectoral specialities preserved.

  • Sistema Especial para la Construcción (within Régimen General): Sectoral sub-regime preserving particular rules on contratos fijos de obra (DA tercera RDL 32/2021), administered jointly by TGSS and FLC.

  • Employer contribution (cotización empresarial) 2026 composite for construction:

    • Contingencias comunes: 23.60 % employer / 4.70 % employee
    • Desempleo (contrato indefinido): 5.50 % employer / 1.55 % employee
    • Formación Profesional: 0.60 % employer / 0.10 % employee
    • FOGASA (Fondo de Garantía Salarial): 0.20 % employer
    • MEI (Mecanismo de Equidad Intergeneracional, Ley 21/2021): 0.67 % employer / 0.13 % employee for 2026 [verify Resolución TGSS 2026 indexation under Real Decreto-ley 2/2023]
    • Accidentes de Trabajo y Enfermedades Profesionales (AT/EP): variable by CNAE-2009 código and tarifa de primas (Disposición adicional cuarta Ley 42/2006 as updated annually). For CNAE 41-43 construction the average employer rate is approximately 6.70 % [verify against Tarifa de Primas 2026], with subdivisions by occupation code (e.g., code “g” estructuras and “j” cubiertas at higher rates).
    • Total employer composite for a construction journeyman 2026: approximately 30.5-31.0 % of base de cotización, plus AT/EP variable; effective non-wage labour cost in the order of 36-38 % above gross wage [verify 2026 final BOE publication].

  • Mutuas Colaboradoras con la Seguridad Social: Private non-profit accident-and-sickness insurers collaborating with TGSS under RD 1622/2011 and Orden ESS/484/2013. Construction employers affiliate with one Mutua (FREMAP, Asepeyo, MC Mutual, Mutua Universal, Umivale); the Mutua administers AT/EP claims and incapacidad temporal por contingencias comunes when so contracted. Reference: AMAT at https://www.amat.es/.

  • Fundación Laboral de la Construcción (FLC): Bipartite institution established by the Convenio General de la Construcción in 1992, financed by an obligatory employer contribution of 0.35 % plus worker 0.05 % (Art. 113 et seq. VII CGEC 2023-2027). The FLC administers the TPC, the Aula Permanente, the Plan de Formación Sectorial, and the Observatorio Industrial de la Construcción. FLC contribution is collected via TGSS. Reference: https://www.fundacionlaboral.org/.

  • A1 reciprocity applies to EU/EEA/Swiss posted workers under Reg 883/2004. Non-EU workers employed directly by a Spanish employer enrol in the Régimen General from day one (Modelo TA.1 affiliation, Modelo TA.2/S alta).

5. Wages & Collective Agreements

Spain statutory minimum wage is set annually by the relevant national authority. Sector-level CBA coverage in construction varies; posted-worker wage parity under Directive 2018/957/EU anchors to statutory minimum or to applicable CBA rates where the agreement has been universally extended.

Spanish wage-setting in construction operates through three concurrent layers:

  1. Salario Mínimo Interprofesional (SMI): Statutory floor across all sectors, fixed annually by Real Decreto pursuant to Art. 27 Estatuto de los Trabajadores. The Real Decreto 87/2025, de 11 de febrero, fijó el SMI para 2025 en EUR 1,184/mes en 14 pagas (EUR 16,576 anual). The 2026 SMI awaits publication of the corresponding Real Decreto following Comisión Consultiva del SMI advice; indicative reference EUR 1,200-1,230/mes [verify against final 2026 BOE Real Decreto]. Reference: https://www.boe.es/.

  2. VII Convenio General Estatal de la Construcción 2023-2027 (CGEC): Sector-wide collective agreement between CNC (Confederación Nacional de la Construcción) and trade unions FECOMA-CCOO and UGT-FICA, registered with the Dirección General de Trabajo and published in BOE núm. 134, de 6/6/2023 (Resolución de 23 de mayo de 2023). The CGEC sets the National Wage Tables (Tablas Salariales Nacionales) for each Categoría Profesional, grading workers from Encargado General (Nivel III) through Oficial 1ª, Oficial 2ª, Ayudante, and Peón Especialista to Peón Ordinario (Nivel XII).

  3. Convenios Colectivos Provinciales de la Construcción: Each provincia maintains a provincial convenio negotiated between regional employers’ associations and unions, registered with the regional Autoridad Laboral. The provincial convenio prevails over CGEC where more favourable (Art. 84 ET concurrencia rules); Madrid, Barcelona, Bizkaia, Sevilla, and Valencia consistently exceed CGEC by 4-8%.

[All 2026 figures indicative; verify against the Tablas Salariales Definitivas to be published by Comisión Paritaria del CGEC and each Convenio Provincial in the BOPRO.]

The standard annual structure under CGEC Art. 47 is fourteen pagas (twelve monthly plus two extraordinarias in June and December), 1,738 horas anuales effective working time, plus thirty calendar days paid vacaciones and the dieta regime under Art. 78. Overtime is restricted by Art. 64 to 80 horas/year except force majeure; structural overtime is prohibited.

Trade-specific context

Industrial welder is the highest-paid construction trade in northern EU when ISO 9606-1 6G position is held alongside RT/UT/PT non-destructive-testing-coded experience. Coded welder = WPQR signed off and on-site weld first-time-pass record demonstrable.

  • Tier 1 (CH/LU/NO/DK + offshore/subsea EPC): €28-45/hr base. CH peaks higher for nuclear and pharma orbital. Offshore day-rates (NO/UK sector) routinely €450-650/day.
  • Tier 2 (DE/NL/FR/BE/AT/FI/SE/IE): €22-35/hr. DE Süd-Bayern automotive and gigafactory at the upper bound; IE pharma/data-centre pipework similar.
  • Tier 3 (IT/ES/PT/CY/MT/GR): €14-22/hr. IT industrial north (Lombardia, Veneto) higher; Mezzogiorno lower.
  • Tier 4 (PL/CZ/SK/HU/RO/BG/HR/SI/EE/LT/LV): €9-16/hr. RO/BG lower bound; PL/CZ upper bound; EE/LT for shipbuilding and Estonian gas works at the upper bound.

Premium adders (cumulative):

  • 6G position certification: +15-25%
  • Duplex / super-duplex / Inconel proficiency: +20-35%
  • Orbital TIG (semiconductor/pharma): +25-40%
  • Subsea / offshore allowance: +30-50%
  • Nuclear pressure-boundary qualification (RCC-M, ASME III): +30-50%

A coded 6G welder with duplex exposure at a Northvolt or Aramco-licensed Jazan-modelled facility will, on combined adders, exceed the Tier 1 base by 30-50%.

6. Accommodation & Welfare

Posted-worker accommodation standards in Spain are governed by general employer health-and-safety obligations under the Labour Code and, where applicable, by sector-specific implementation ordinances setting square-meter-per-worker minima, sanitary-facility ratios, and ventilation/heating requirements. Practical norms on multi-trade sites typically follow national contractor codes of practice.

7. Language Requirements

Spain’s official administrative language applies to inspectorate notifications, social-insurance filings, and regulatory submissions. Site language fluency expectations follow from the supervisor’s working language and the safety-driven inspectorate posture.

There is no statutory CEFR threshold for entry into construction work. Spanish (castellano) is the official state language under Art. 3.1 of the Constitución and the default for site safety briefings, charlas de seguridad, and PRL training under Ley 31/1995, de 8 de noviembre, de Prevención de Riesgos Laborales (BOE núm. 269, de 10/11/1995). Autonomous communities with co-official languages — Cataluña (català), País Vasco (euskara), Galicia (galego), Valencia (valencià), Illes Balears (català), Navarra (euskara, zona vascófona) — apply regional co-officiality under Art. 3.2 of the Constitución.

In practice castellano is sufficient on virtually all sites including in co-official-language communities; PRL documentation and Plan de Seguridad y Salud are routinely bilingual or Spanish-only in mixed teams. DELE (Diploma de Español como Lengua Extranjera, Instituto Cervantes) is the standard external certification: A2 training cost EUR 380-550 plus exam EUR 130; B1 training cost EUR 600-850 plus exam EUR 160. RD 1004/2015 recognises DELE A2 as functional minimum for nacionalidad por residencia. Bayswater calibrates ES deployment-readiness at DELE A2-B1.

8. Compliance & Enforcement

The host-state labour inspectorate conducts site audits with statutory powers under the labour code and posting-regime ordinance. Audit triggers include targeted inspections on high-risk sites, complaint-driven inspections, cross-agency referrals, and routine audits on randomly selected posting notifications.

Common compliance traps cluster around late posting notification, A1 absence, document-translation overhead for non-Latin-script jurisdictions, and CBA wage-parity assumptions where the host-state CBA universal-extension status is variable.

  1. TPC missing on site: Most frequent ITSS finding. Workers without TPC are denied site access; the contratista principal bears responsabilidad solidaria. Bayswater protocol mandates FLC training and TPC issuance before mobilisation.

  2. ITSS notification omission (REGCON): Posted-worker notifications submitted post-mobilisation, missing the autonomous-community filing, or omitting the designated Spanish representative under Art. 4 Ley 45/1999. ITSS cross-checks REGCON with on-site presence and issues actas de infracción at grave or muy grave classification.

  3. CGEC convenio wage non-parity: Application of home-state wage rather than CGEC plus applicable Convenio Provincial. Failure to apply Madrid, Barcelona, Bizkaia or Sevilla provincial rates is a wage-parity violation under Ley 45/1999 Art. 3 and triggers responsabilidad solidaria of the principal contractor.

  4. FLC contribution evasion: Failure to remit the 0.35 % employer + 0.05 % worker FLC contribution alongside TGSS cotizaciones. FLC verifies via Cuenta de Cotización cross-reference; arrears trigger recargo de mora plus LISOS sanction.

  5. Subcontracting chain breach (RD 1109/2007): Chains exceeding three tiers without ITSS-approved exception, or first-tier subcontractor failing REA acreditación. Sanctions classified grave per LISOS Art. 7.10 bis (EUR 751-7,500), escalating where REA non-compliance is detected.

9. Cost-Per-Worker Breakdown (First Year)

Indicative cost stack for a posted industrial — welder on a 12-month deployment to a Spain construction site:

ItemEUR / worker / yearNotes
Gross wage (sector journeyman)35,000Tier-1 wage destination; varies by CBA
Employer social-insurance contributions9,000~25% of gross; varies by jurisdiction
Sector-fund contributions (where applicable)2,500SOKA-BAU equivalent / construction levy
Visa/permit fees (one-off)500Single Permit or Blue Card application fees
Qualification-recognition fees (one-off)200Per qualification recognition
Document-translation overhead (initial)300Variable by document count
Accommodation (employer-provided, indicative)6,000EUR 500/month; varies by location
Total deployment cost~53,500First-year, fully loaded; excludes per-diem and travel

10. Operational Warnings & Red Flags

  • Pre-arrival posting notification is non-negotiable: late notification is treated identically to non-notification under the host-state Posted Workers Directive transposition. Build the notification milestone into the pre-deployment T-2 weeks checkpoint.
  • A1 absence triggers parallel host-state social-security liability: a posted worker without a valid A1 from home state is presumed host-state-affiliated from day one of work, with retroactive contribution liability cumulating monthly.
  • CBA wage-parity verification: confirm the host-state construction CBA’s universal-extension status before pricing the deployment; assumption of universal applicability is a common compliance error.
  • Subcontracting chain liability: where the host state imposes joint and several liability across the subcontracting chain, the principal contractor bears risk for sub-tier wage and contribution compliance.
  • Sector-fund registration (where applicable): SOKA-BAU (Germany), Constructiv (Belgium), CIBTP (France), Cassa Edile (Italy), BUAK (Austria) — verify whether Spain’s sector-fund regime covers industrial — welder deployment and pre-register before site arrival.

The reclassification by the International Agency for Research on Cancer covers welding fumes from all base metals, with hexavalent chromium (stainless welding) and manganese (carbon steel) as primary toxic components. IARC Monograph 118 (https://publications.iarc.fr/Book-And-Report-Series/Iarc-Monographs-On-The-Identification-Of-Carcinogenic-Hazards-To-Humans/Welding-Molybdenum-Trioxide-And-Indium-Tin-Oxide-2018) is the source. EU Directive 2004/37/EC on Carcinogens, Mutagens and Reprotoxic Substances (Carcinogens Directive, https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:02004L0037-20220405) requires LEV (local exhaust ventilation) at the source, substitution, and annual health surveillance. Zinc (galvanised steel — fume fever) and nickel (nickel alloys — sensitiser) add further exposure pathways.

Burns and UV/IR exposure. Arc-eye (photokeratitis) requires CE-marked auto-darkening helmet to EN 379 (https://standards.iteh.ai/catalog/standards/cen/) and welder’s leather PPE. ISO 11611 governs welder protective clothing (https://www.iso.org/standard/57455.html).

Confined-space welding. Tank, vessel and pipework interiors require atmospheric monitoring (oxygen, LEL, CO, H2S), forced ventilation, standby/attendant person and rescue plan under EN 1127-1 (https://www.iso.org/standard/72606.html for the ISO equivalent) and national confined-space rules. Employer is normally required to issue a confined-space entry permit linked to the hot-work permit.

Electric shock. AC welding carries higher shock risk than DC in damp or confined conditions; EN 60974-1 (https://www.iec.ch/publications/welding-equipment) governs welding power source safety. Insulated electrode holders and dry footing required.

Hot-work permits are mandatory under PED-relevant operations and most EPC site procedures: fire watch for 30+ minutes after weld completion, area ATEX-zoning check, gas-cylinder securing and slag/spatter containment.

PPE baseline: leather welder’s jacket and spats, FFP3 respirator (or PAPR for stainless/galvanised), auto-darkening helmet (EN 379), gauntlets to ISO 11611, safety boots, ear defence (gouging operations).
