Hi folks.... I want to do some car bodywork soon, so thought I'd try on some sheet metal. It's 0.9mm sheet and I'm using 0.6 mig wire on a Clarke 160t with hobyweld 15 (2% oxygen, 15% co2 and 83%argon). Welder is on lowest power setting with wire speed 6-7. Any advice appreciated, i know I've burned through in a few places, especially where the fit-up is poor. Apart from that is there a hand technique I should be using? I'm just doing what seems like squiggles....or small circles...but the result is a very high weld which will take an age to grind down.
