Regulator Setting c25 - Stich Welding Auto Sheet Metal - New
Posted: Sun Mar 04, 2018 7:53 pm
Hi all,
Finally setup my Lincoln 175 (220)(been sitting new in its box for years) because I need to patch in some new sheet metal onto my truck. I had a few questions and hoping to get some advice. Will be using c25 indoors in the garage. From my reading I should have my regulator set between 15-20 and/or 10? My Harris 601 has 2 sets of numbers L/min and scfh, which one should I be using and are my number correct?
I have a donor car that I sliced some of the side panel off from and then cleaned. The metal feels pretty thick and strong, much thicker that I thought it would have. It's from a 2001 saab. Using my caliper gauge the measurement looks like 0.75 mm so its about 21 ga looking at my Lincoln chart. I set up the welder at A 2 and bumped it up to A 2.5 for the test welds. Used some butt welding clamps which keeps a gap in between the metal. I was only able to get one tack to span the two pieces nicely. The rest was pretty terrible, making the two pieces connect was challenging . I will be stitch welding the final repair when I am able to dial in the welder and technique.
Should I first trying running straight bead before attempting to tackle stitching up the gap between the butt weld clamps? Assume that I have to start the puddle on one side of the gap and then flick my wrist to wick it across or am I just hitting the center and trying to make double contact?
Thoughts and comments?
