I can weld Ok in the centre of 1mm sheet by pulsing, and overlap joints, no blow throughs and pretty decent penetration. However, today I had a go at joining 2 pieces of 1mm, with a 1mm gap and i just cant get the puddle to flow across the gap consistently. I have a few questions. 1) When butt welding 1mm car panels is it advisable to leave no gap?
