With my '66 I had to learn how to MIG weld so I could redo the quarters, floors, and other misc work. I was able to pick it up relatively easy, and have been really thankful that I learned the trade.
However, now I have to do some aluminum welding on my Vette project, and let's just say the learning experience has been nowhere near as fun. I'm using a Lincoln SP-125 Plus with the aluminum feeding kit, 4043 wire, and getting all the info I can off the web. The metal I need to weld is .060", and man is it tougher to get welded than steel.. I guess I just typed this email to vent and see what other tips others might be able to provide who have gone through the same experience- my biggest misconception is that knowing how to weld steel might help me along with being able to weld aluminum.. WRONG! 8^] Regards, Jim '66 Malibu http://mywebpages.comcast.net/jbiii/my66.htm
