Thank you to everyone for the advice. While I am planning on using this mostly inside the garage on 220V.... I can also see a real need to use it in the driveway on 110V.... (unless I either have long 220 extension cord or longer leads for the stick welder). I was using the stick with the indicator sat at 112.... does that indicate 112A? Also, is there anyway to rotate the air intake on the plasma plug? I have it setup per the drawing in the manual and my airline turns straight down... this puts a bad bend in the airline and I think it is restricting the airflow.... if I can rotate this 180 degrees, the airline will go straight up.... if not, I will put a block under the unit to raise the front. (I am using the better welding cart from HF if that helps in the visual)
