I carefully filed the electrode that had can steel stuck to its tip, and made sure it was same size and shape as the other.
Flipped a cell over in holder and tried welding the + tab with the same settings. no Flooux
No preheating, triple pulse, 2ms interval
Two very even, weak welds lifted off very easily.
Tiny holes in copper, didnt bother with photo
Tried again with gear 750, 1ms interval, triple pulse.
Notice the steel colored ejecta on the weld on left. That is not a weird reflection, it is steel colored. could there still have been steel stuck on electrode? I was pretty sure I got it all, but perhaps there was some on the side.
It too lifted off pretty easily, but left the copper behind.
