If I'm broke like usual, something like a Lincoln pro mig. That's what I used with auto body work and some exhaust and headers. If I can really choose, pretty much anything from Miller. Their stuff just works and works really well. I learned to stick weld with millers and they are wonderful. I used a tig from them once, it was a dream too.
Mig is probably the most versatile as well as easy to learn, but there no really one welder that can do it all. However if I could only have one I'd probably go with Tig inverter that can also stick weld. Tig welding is quite difficult to learn though.
Same here. Thinking about buying a welder soon and would like to hear what the community recommends. Personally I want something versatile; able to MIG and TIG. I’ve heard ESAB makes good equipment.
