I wasn’t just trying to make pretty welds. I was making some gaps, off height welds, cleaning with brush and acetone all the way to no cleaning at all. I had hertz high 170, down to 100. Amps stayed around 85-90 ish with some pedaling(1/16 coupons)Trying to get some tips for when they butt up to each other off height. Do you focus the arc toward the lower piece? Any advice appreciated
