Re: [CAD_CAM_EDM_DRO] TIG Welders

14 gauge 3 conductor wire ???

Been there, started that fire. NCG 180 amp AC stick welder. Good thick
plate to plate weld....crank up the amps....... weld ...... get fire
extengiusher........ get parts & make big extension cable.... finish weld.

14 gauge wire is normally rated 15 amps. Not a good idea if the device can
trip a 30 amp breaker.

14 gauge 15 amps
12 gauge 20 amps
10 gauge 30 amps
8 gauge 45 amps

Not sure about these, no book handy but probably close.
6 gauge 55 amps
4 gauge 75 amps
2 gauge 100 amps

And just going up a wire size over the minimum never hurt anything.
