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.

The Australian reality

Most Australian hobby MIGs run from a standard 10A power point; 15A circuits unlock the 200A+ class for structural work.
