This is the one I'm using and it works great with gas or flux core
wire. I've used it to weld body panels and up to 3/8" steel bars and
it lays a nice weld without any effort. I had never used a wire
welder before, always used a stick welder, and the first time I used
the wire welder was so simple and easy. It lays down a nice clean
weld without any effort. MOHP I have found the gas does a much better
job on thin metal, but the flux is much better on thicker metals.
