Spot welding
Can you do spot welding outdoors?
Quick answer
Yes — no shielding at all, just clamp and squeeze. Weather matters mainly for the material being dry and clean at the tips.
Wind thresholds that matter
| Process | Wind tolerance | Fix |
|---|---|---|
| Gas MIG | ~8 km/h | screens, or switch wire |
| TIG | worse than MIG | indoors only, realistically |
| Stick / flux-core | high | none needed |
| Laser | site-dependent | follow safety documentation |
The Australian reality
Handheld and bench spot welders in Australia run from $250 portable units to $2,000+ pneumatic bench machines; auto-body quality usually needs a proper pneumatically-assisted unit.
