Better?
Only changes I made from previous was to go down to setting number 2 and upped the wire speed a little. To me, it looks a lot better. I tried a couple different techniques including just moving in a straight line. Going around the tube is some what of a pain, but oh well, I'll practice. The last picture is after grinding. Initial tests show it doesn't leak through those welds. That was a pair of welds, too.
Thanks
