Hey, just bought me my first Mig welder, it's a draper 135 amp turbo mig...I'm liking it so far but.....We were having a go at welding aluminium and my mate might have gotten the wire stuck in the liner.....Don't ask how but we don't have either ends and I don't know what to do! Also whats the best plan on gas bottles....think I need a mostly Argon mix with small (7% CO2 content?) for welding thin steel (some chassis work but mostly body and bulkhead) and stainless steel - obviously i don't want to pay for two bottles! How much do BOC bottles cost as the little ones are just too pricey! Used 2 just mucking about!! Phoned air products but they were gonna be £102/year rental and £25 to fill up. Guy was nice and would be happy doing business with him but it's a lot of money - especially on rental....any suggestions???....Cheers Oli.
