I'm completely new to this... I've been tig welding just mild steel for about a year. I walked into a welding shop and bought a mig welder and a tig welder, brought them home and thought to myself "what have I done?"... I've never welded anything in my life... not even shop class. Anyway, now I'm trying to get aluminum tig welding down and I'm having a little trouble. I'm trying to do some really nice corner welds on 1/8" aluminum sheeting. It's 5052 aluminum with the coating on it. I clean everything really well, but I still have a horrible time with the starts of the weld. I close out the weld real nice by backing off the pedal, but the starts look horrible. Does everyone else start on the corner where the two plates meet or do you start in the middle and work you're way out to the edge? Anything you can do to help would be great!! Oh, and I'm using 3/32 filler with the same size tungsten. Pure tungsten. I really would like to make these welds look nice... please help...
