Hi guys n gals. I'm new here and would like a bit of advice from the guru's out there. I've got a Wolfweld turbo Mig 105 ( yes, yes, i know !! ) and want to weld thin sheet metal ( a repair to my bike exhaust ). The book says the welding amp range is 35 to 90. is the low range ok for 0.6mm wire and where can i get a spare wire feed wheel from, one with a 0.6 slot that is ?? The wheel that's on at the moment is for 0.8 and 1.0mm wire. Brilliant site by the way, only wish like others i had found it first.....
