My tool of choice is a little backpack 100 amp DC inverter stick/TIG unit I picked up on eBay a few years ago. It ran me just over $300 at the time, and came with a 12' TIG torch with a manual gas valve as well as a stinger for stick electrodes. It's the size of a shoebox, has enough jam to burn 1/8" 7018 rods, and gives me the ability to weld stainless and CroMo. The only thing I don't like about it is the lack of HF start.
For someone just starting out, try looking for a used name brand unit at your local industrial/machinery auctions. Buying a no-name flux core unit or a no-name inverter welder and having it break down on you while you're learning to weld is a surefire way to get fed up and quit before you've even got started!
Yeah, it does kinda suck. For my crappy HF arc/tig welder, I just made a 25ft extension cord and plug it into the dryer outlet inside.
@Dan, here in the US, 3-phase is industrial. Houses only have a 240V power supply :/
Our wire is measured in inches. Like .045 wire is about the largest that MIG welders use.
i have 120v... lol. my $100 harbor freight 90 amp FCAW works perfectly... i have not one thing bad to say about it.
i even use HF wire sometimes. i find it not too bad actually. most people hate the stuff though.
for me, welding frames, no more than 1/4" thick, it is a wonder.
and on my circuit breaker, sometimes it blows when i weld for a long period. i have to reset it every once in a while, but its not far away, it doesnt bother me.
