Safety
Can you weld indoors safely?
Quick answer
Yes — with ventilation as the non-negotiable. Weld indoors safely by extracting fume at the arc (local extraction or a strong cross-draft), screening the arc from others, clearing flammables within 10 metres, and never welding near solvents, dust collectors or combustible ceiling voids.
The indoor checklist
- Fume extraction at the arc or a genuine cross-draft — not a closed garage door
- Fire watch: hot slag rolls and hides; check an hour after finishing
- Clear flammables and sweep the floor — sparks find rags and cardbard
- Screen the arc — every passerby needs protection from flash
- Cylinder security: chained upright, valves closed when not in use
