Got my new shiny red portamig and lovely bit of kit it is. I am a bit stumped though. I have bought some 0.8mm mild steel as intend to repair some car panels. Have followed some guides on here and can get a nice-ish weld going but I have to have the voltage on 1-5 or 2-1 to get any kinda penetration. Is this odd or am i doing something wrong? Because I thought for thin metal I would be using a lot lower setting, but this doesnt penetrate and just creates a pea.
