I have the sweet Tassajara made by Gary Fisher.. (I think it's sweet) .. anyway it is an aluminum bike and the chain derailleur cracked off and I was wondering if I can use this welder I just bought for 100 that looks like new **applause**
Amazon.com: Schumacher - Turbo 145 MIG/Flux Welder - 120 Volt (90441): Automotive
and want to weld the piece that holds the derailleur back on. I have some experience with steel welding but never attempted aluminum before. I can practice on some other parts and seat posts to get a feel before going at the main course. Can this be done? I have dozens if not a hundreds of hours behind a sloppy stick (please refrain) and flux wire feed welders.
Anyway that said.. I will someday make a near aluminum frame frankenbike now that I have this welder.
