If you are new to MIG welding & considering taking the plunge buying a set & having a go, which do you buy, a traditional gas type or a gas-less?
Most of you will probably be investing in a set to do some car repairs, if that is the case forget the gas-less.
0.8mm is the smallest diameter wire available in flux cored gas-less wire & this is too thick for very thin materials; the thicker the wire the more current is needed to melt it. (0.6mm is the best) Whatsmore, gas-less welding is not as smooth as traditional gas type welding, producing a more unstable arc which causes blow through on thin sheet.
There is no real cost savings involved either as the flux-cored wire is 3-4 times the price of standard wire!
All that said, gas-less is fine on thicker materials, great if you suddenly run out of gas on a Sunday & more portable in that there are no heavy gas bottles to lug around.
BEST ADVICE: If you are unsure (or you don't believe me!) buy a DUAL PURPOSE machine. That way you can experiment in both modes & you get the best of both worlds.
