Have had a little time to play with the second machine ,I have worked around the one small issue for now,I tried the machine on some 1/8" aluminum and some 095 mild steel tube. I used 1/16" dia ( 3/32" would do better) rod for the Aluminum and steel, I tried 4 different amp settings on the alum settled in around 70-75 seemed best no pedal torch only.Ran the steel tube at 70 amps with the 1/16" rod and did just fine. Looks like a good machine and will do fine. I have some camera mounts to fab up today and will post a few pics along the way.
( Got my son in law under a hood and let him weld too) He picked it up pretty quick.
Pictures don't look like much but we were just playing around with some scrap
