The horizontal and overhead welding allows the weld to "Build" as I move along, but the overhead areas tend to drip out even though I tried several different settings on the welder. Falling globs of melted metal scare me a little.
I see what you mean... the welding of new & uncontaminated metal to 41 year old Detroit steel could be an issue. On the workbench, welding 2 new pieces together, the welds look great and the beads are not irregular or "Popcorn" like at all. I ran a knotted wire wheel on everywhere I intended to weld, so at least the surfaces looked clean. Its done now though. To finish the trouble areas, I had to do a series of quick ZAPS, then tune it all up with the 4" grinder.
This isn't the last car that I will do, so i am still interested in any other suggestions anyone has. Thank you all!
