I'm butt welding 3mm steel and struggling with penetration.
If I'm moving slow enough to get reasonable penetration, the bead is flat and looks over cooked.
If I'm moving fast enough to get a good looking bead, there are no signs of penetraion on the back side of the joint.
I'm running at 90A (as per this site's amps chart) and have tried +/-10 amps, but cant (yet) find a combination of amps and speed that gets a decent weld bead and decent penetration.
Any thoughts?
