Problem with the duty cycle is it is in minutes on welders.
As in 10 minutes on welders.
A twenty percent duty cycle is weld 2 minutes let cool for 8 minutes.
Far better off to get one that welds at 100% duty cycle at an amperage you commonly weld at and lower.
Mine I think is 100% at 90 amps.
It has a square wave form on AC and is I think 40%+ 60%- or the other way around for welding aluminum.
MIG welders have voltage and feed settings, most of the guys you see on TV dont know how to use them or set them up.
They are fantastic for thin metal speed and tacking.
A friend of mine ran one at a Caterpillar plant that was huge they brought the spools in on a lift or crane.
Ran off Co2.
