It was 93 here today and only going to be 75 tomorrow.
ha,ha shredded dollar bills I can relate to that. How many times did you utter some very colorful expletives when you stuck your tungsten or the glob on the end of it looked like a kidney stone growing?
It's been so long since I've done and aluminum with a tig that I can't offer any cool tips or advice other than this whe3n you get ready to weld aluminum brush it with a stainless steel brush where you want to weld. Even if the metal looks like it is bright shinny and new hit it with the brush I like using a 4 1/2" angle grinder and a 4" brush, and don't be afraid to really lay into it. I find when welding aluminum with an oxy act torch or more recently when I used them spool gun the results were dramatically different.
