Re: 130 amp mig welder good enough?
Like everything it depends what you want to do with it. I have cheap 90 amp fluxcore MIG that does everything I want it to. Welds are ugly, but that is probably as much me as anything. Up side to a "low amp" welder is the fact that they are usually 110 and you don't need any special wiring for them. That may not matter "down under" though. If you are just going to make bike frames a 130 is fine, if you are gonna make horse trailers or armor plate your bike with 1/2 steel, you may want to look into the 200 amp model.
