What I basically want to know is, is it at all possible to weld aluminum with this welder? I tried to weld a piece of thin guage steel the otherday, and at 40 amps I blew a huge hole in the piece of steel. So, my concern is, what would this welder end up doing to aluminum? This is only going to be a "once in a while" type thing, so I don't want to purchase a ReadyWelder or anything like that. I just want to know if it is possible to stick weld with this particular welder.
