It looks very cool. Is there significant risk of warpage when using it?
-Rusty :toke:
Warpage isn't a big problem with a spot welder.
Getting the weld just right can be challenging. Too much and the metal squeezes out, too little and it doesn't stick together.
There are three different parameters that go into a good spot weld - Power, Time, and Clamping force. Gotta balance them all.
