I hear you. I havent messed with the small machines much. But sounds like they're perfect for around the house, thin metal, implements and such. I'm curious as to how they would handle aluminum beings it takes so much heat. I've used the spool guns with gas on bigger machines for aluminum and it's cake. But I still rather heliarc aluminum. Just a better weld IMO. All my original welds broke on my boat which were mig. I rewelded all welds with heliarc and haven't had a problem.
