Spot Weld Nozzle
Product Review (submitted on November 5, 2012):
I found this very usefull. The main key this using this is having absolute metal to metal contact at the point of the weld, otherwise your pissin in the wind. I ordered it without the pliers, but wonder if it would have been better with them. it produces a very flat , hardly raised weld that does penetrate. It doesnt work in all locations but then neither will a spot welder.
