Have a Diversion 180. Using 1/16th 2% ceriated with argon set to 15cfh, 3/32 Er70s-2 filler rod at 75 amps. Doing practice lines on clean 16 gauge mild steel coupons . Im keeping a slow steady constant speed across the steel while welding and the welds are coming out smooth, no ripples in some sections. Even if i use stop and go or move forward then back a little in small increments it still stays smooth, Im holding the torch at 70 degrees as recommended and pushing the puddle, not dragging it...cant seem to get steady ripples, am I doing something wrong here?
