I'm getting into TIG welding bits of 3mm thick ali extrusion. I'm getting some solid joints, but the welds end up being quite wide if I use enough current/time to get decent penetration, maybe 8...10mm wide. I've seen rather narrower welds on professional fabrications in the same thickness material, wonder what I'm doing wrong. I'm using a 2.4mm Zr tungsten and about 85A AC, more or less 50:50 balance as otherwise the tungsten seems to get rather too large a ball on the end.
