Hi there, I want to start learning to mig weld so I can patch up my car. Bought this little 175 Xcel-Arc welder second hand but cannot find any information on the settings. There's no handy chart on it. Just wondering if anyone can give me some basic starting settings : Argoshield setting, wire feed and voltage settings. I guess using mainly 18-20 gauge steel for panels, but also heavier gauge, say 3mm for chassis stuff. Possibly welding captive nuts etc. Any help and advice greatly appreciated.
