Thread: TIG or MIG welder
Tig is easier to pick up if you've gas welded to a standard where your welds are a lovely neat series of half-moon shapes, you understand about maintaining a weld pool and where using filler keeping the rod tip at the right temp and dipping it to add filler. If you need to work with thin Stainless or Aluminium Tig and Gas are by far the best options.
MMA (Stick) is brilliant for heavier work in most materials, building up worn surfaces on machinery and hard facing, it's also excellent for outdoor work as not relying on gas for shielding it's tolerant of wind and even a bit of rain when you need to weld a hinge back into your neighbor's gate post on an inclement day.
I would have all three if possible, but if choosing one it depends on the intended use.
If you want pretty welds in light materials then your only option is TIG, also TIG if you're predominantly working in Aluminium and Stainless in a workshop.
Generally speaking if you're working with materials above 1mm and you're happy with some post-welding cleanup on finer work then a MIG will do the job nicely, I've built Mini-Skips outdoors on a calm day with a MIG ;-)
Never underestimate Stick, on fabrication work it will perform and produce a lovely job outdoors where MIG and TIG will struggle to function,

I'd have to agree that Mig will do most jobs but there are occasions when TIG and ARC are more suitable. If you have a workshop and 3-phase, then I'm assuming you're setting up something a bit more professional than a garden shed workshop? If so, get a 3-phase MIG welder and a small inverter TIG/ARC. The latter will often be combined into one set as they're almost identical electrically. Inverter driven arc welders are an absolute joy to use. I bought one of these last year for £300. It's been better than expected, however it drinks Argon faster than I can drink scrumpy!

Thanks for all your advice folks. I'll have a good look into a 3 phase and good look into MIG in general.
