I had a hand held spot welder, i think it was an SIP from memory.
It was quite powerful but only was fit for a handful of spots per minute before the handles got soo hot you could hardly hold it lol, but it was fine for body repair.
I sold it because i needed a more production line type of...
Sure what's not made in China lol
It's a Stahlwerk welder with a decent reputation/guarantee.
No probs with heat, I'll mostly be using the pulse mode for 3.5mm, and standard mig for .9mm, it's actually quite good on the thin stuff in standard mig.
Having a blast with my first synergy mig, lots of buttons and functions that my old 25yr old welder didn't have.
Early days yet but it's an improving picture, it's such a nice way to weld, i wish I'd bought one yrs ago!
All mig pulse hints and tips to speed up my learning curve greatly received.
