Hi Marea Mad, I'm a reasonable handyman, but could you please enlighten me as to what a "mig" welder is. The trouble with soldering light, delicate electronic components is that you need 3 hands or more; one to hold the iron steady, the other to smelt the solder onto the tip, and then the other and a third to hold the iron while securing the 2 pieces in place. I've never found suitable clamps for holding for what are essentially fragile gossamer butterfly wings. Maybe I should've done that City & Guilds course in my youth.
