MIG welding
Can you do mig welding outdoors?
Quick answer
Only with shelter: any breeze over ~8 km/h blows the argon shield away and the weld goes porous. For real outdoor work, switch to flux-core or stick — or rig proper windbreak screens.
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
Most Australian hobby MIGs run from a standard 10A power point; 15A circuits unlock the 200A+ class for structural work.
