Welding overalls are one of the most important items of PPE for any welder — protecting against spatter, arc flash, radiant heat and UV radiation. Wearing the wrong garment is not just a compliance issue; ordinary synthetic workwear can melt onto skin when exposed to welding spatter, turning a minor incident into a serious injury. This guide covers the standards, the processes, and the best options available in Ireland.
Why Welding Requires Specialist Protective Clothing
Welding exposes the operator to a combination of hazards that standard workwear cannot address: molten metal spatter at temperatures of 1,500°C or more, UV and infrared radiation from the arc, radiant heat from the weld pool, and in some processes, open flame. Materials that are not inherently flame-resistant — polyester, nylon, most poly-cotton blends — will ignite or melt when contacted by spatter, causing the clothing to adhere to the skin and dramatically worsening burn injuries.
Welding overalls must be made from inherently FR materials — cotton, wool, leather, or synthetics with FR treatment — and must be CE certified to the relevant EN standard for welding PPE.
EN ISO 11611 — The Welding Clothing Standard
CE-certified welding clothing in Ireland must meet EN ISO 11611, which defines two classes based on the welding process and associated hazards:
| Class | Hazard Level | Welding Processes | Key Properties |
|---|---|---|---|
| Class 1 | Lower risk | TIG, MMA (low spatter processes) | Basic spatter resistance, limited arc protection |
| Class 2 | Higher risk | MIG, MAG, plasma cutting, high-spatter processes | Greater spatter resistance, higher arc protection |
For most professional welding in Ireland, Class 2 is the appropriate specification. Class 1 is acceptable for TIG welding and lower-risk manual metal arc processes. The standard also requires the garment to meet minimum performance levels for limited flame spread, heat resistance, and tensile strength.
Welding Overalls vs Welding Jacket
Both are legitimate options depending on the work environment:
| Garment | Coverage | Best For |
|---|---|---|
| Welding coverall / boiler suit | Full body — torso, arms, legs | Production welding, workshop environments, fabrication |
| Welding jacket | Torso and arms only | Short welding tasks, site work, combined with FR trousers |
| Welding bib apron | Front torso and upper legs | Light welding, bench work — see our welding aprons guide |
For full-shift welding work, a coverall offers the most comprehensive protection and the least risk of gaps between garments. For occasional welding or site work where mobility is important, a jacket and FR trousers combination may be more practical.

| Sealey / Draper | Budget welding suits | Class 1 | Available in Irish hardware stores — check CE certification carefully |
What to Look for When Buying Welding Overalls
| Factor | What to Check |
|---|---|
| EN ISO 11611 Class | Class 2 for MIG/MAG and high-spatter processes. Class 1 minimum for TIG. |
| Material | 100% cotton or FR-treated fabric. Avoid polyester or poly-cotton blends — they melt under spatter. |
| Stitching | FR stitching is required — seams sewn with standard thread can fail under heat exposure. |
| Fastenings | Metal press studs or covered zips — plastic buttons and exposed zip teeth are hazardous near welding arcs. |
| Pockets | No external breast pockets — these collect spatter. Covered or internal pockets are preferred. |
| Fit | Snug enough to prevent loose fabric near the arc, with enough room for movement. Avoid overly baggy fits. |
Additional Welding PPE
Welding overalls are one part of a complete welding PPE system. They should be combined with a CE-certified welding helmet (EN 175), leather or FR welding gloves (EN 12477), welding boots rated for heat and spatter, and appropriate respiratory protection where fumes are present. See our welding aprons guide for additional upper-body and front protection options.
Frequently Asked Questions
Class 2 EN ISO 11611 certified welding overalls are recommended for MIG welding due to significant spatter production. Always combine with appropriate gloves, helmet and respiratory protection.
No. Ordinary coveralls made from polyester or poly-cotton blends can melt when exposed to welding spatter, causing serious burns. CE-certified EN ISO 11611 welding overalls made from inherently FR materials are required.
Bizweld is Portwest's welding workwear range, certified to EN ISO 11611. One of the most cost-effective CE-certified welding coverall options in Ireland, widely available through Irish PPE and workwear retailers.
