Lesson learned? You can't have any gaps in the fit up; none at all. If you do, you'll burn holes all over the place.
I got the bright idea to cut some strips to use as practice coupons. I cut them to 1.5 inches wide by 6 inches long. The problem lies with the method I was cutting them. I decided to use tin snips because I thought it would be faster than a cut-off wheel. Not only was it not faster, it was bending the strips all to hell. I thought no problem, I'll just smack them with a hammer afterwards. The hammer didn't get them perfectly flat. I kept burning holes all night. Finally, I found two pieces that were not cut with tin snips. I welded them together as a T joint and it was a breeze. Weld turned out perfect. Never again will I use tin snips to cut out coupons.
