Best way to separate pinch welds

Bodyperson said

NICE. The CP zip gun is very forgiving. It hits hard but the trigger lets you deliver them one stroke at a time. I have custom ground bits. Some of them very sleek and sharp. Ya, it goes against the grain of " chisel " principles but it works for me.

Ive only ever used the big snap on ones so i think thats where i went wrong, and that was for floor removal on VW busses, hundreds of spot welds on thin crossmembers, they are more or less a one handed jack hammer with two modes, off and destroy, the ones i used at least, a good controllable trigger is the most important thing on any bodywork tool, maybe one day ill add a good zip gun to my collection but for now ill be on the hunt for putty knives to sharpen lol
