Don't forget there is a fan and radiator involved to cool the heated water.
We do have some guys doing limited air arc...but the electrodes are fairly small that they use.
You may want to make a try for our NEW PA 300...or our MTS 400 with a special setting just for air arc.
I was just thinking of running 1/8" carbons. How well would it work at that? Arcair's website said the 1/8" carbons need 60-80 amps, but I am not sure if running those are harder on the machine then normal welding, I know next to nothing about air carbon arc. The problem with a bigger machine for me is that I only have 30 amp power, I am just going with the PA-200 for duty cycle reasons
You know I always thought I could tell the difference in a machine that had a steady diet of gouging. But take into account we always ran 3/8 and 1/2 inch carbons, in the 400 + -amp range, on engine drives. Hey if you're gonna move some iron, then move some iron:laughing:! In the 1970's I worked in a fab shop for about 3-years, they had a dedicated 700-amp Lincoln electric machine just for carbon arc gouging, sometimes we would use 3/4 inch carbons, with a couple hundred pounds of air behind it! Few hours of that and your arms started to cramp up!
This subject came up a few years ago on the Miller forum, one of the Miller techs jumped in and said there is no proof that carbon arc gouging will damage a welding machine:confused2:. To this day if my plasma couldn't scarf it out, I'd rent a 400-amp engine drive to do it. In my opinion, welding machines are for welding, old beat up almost dead welding machines are for carbon arcing.![]()
If you plan on buying a PowerArc 200, I would surly keep it for a "welding" machine. Your next concern is air! Carbon arcs eat air like candy! They use to sell a two hole carbon arc torch, but most are three hole, the two hole torch is what I'd look for if using it on a home owner type compressor. We never used anything less than a 185-cfm. I'll tell you what, carbon arcing with a compressor that can't keep up will make the Pope curse:laughing:!
