Thanks for the info. Yes I am mig welding. i am welding on stainless pipe to mild steel flange ring. What gas pressure is recommended, I am using a 1/2" nozzle and am currently running around 35 psi on flowmeter. I experimented today with a higher voltage and wire feed today and had better results, but still not even welds all around. I am using a robot for this procedure. I am welding the o.d. of the part first, you could almost say in horizontal position, then flipping it over on a rotator a 90 degrees and running the inside bead about 10 - 15 degrees from center, dragging the puddle downhill. I have to make a small weld on the inside and it does good part of the way around then will mess up. I am not having any problems with the outside bead, but can't run the inside the same. I will try turning gas pressure down to see if this helps. the weld is wetting in good except for where it is moving around. thanks again, any more would be appreciated. Johnny
