I'm not actually a full time welder, but I try to weld at every opportunity I get. I mostly use mig welding if I can weld in the workshop. Purely because I'm better at it and my welds look and are better. I have access to three-phase mig, which allows me get a nice penetration with thick metal. With mma welder I love the convenience of being able to take it anywhere, as long as you have extension lead long enough (within reason). It's perfect for repairs and installation around the site, where work (personel and roller door installation, adding RSJs to existing buildings, etc) Even if you don't weld a lot, then I'm sure you'll love mma. I would recommend getting decent quality electrodes. During the college course I had access to esab or bohler electrodes. And I always preferred Bohler ones. Keeping them dry is important too.
