For years I used 0.6 wire, mainly on bodywork etc & upto building my chassis I would have said exactly the same as Bonzo, 0.6 all the time no probs.Then I ran out of wire whilst building my chassis & got some 0.8, what a difference.
I can turn the power down and wire speed down, I have less tendency to blow through on butt welds and generally everything is just a bit easier I find, it may be just me but I wish I`d tried it years ago
