Hi folks,
I have a lot of welding experience but haven't used my spot welder all that much. I have a project where (to limit distortion) I want to spot weld a 16ga (1.5mm) piece of hot rolled (can't get cold here) mild steel onto a rectangle made of rolled 1/8" (3mm) thick angle iron.
I'm using a Miller 2.5kva spot welder.
I have read that HR is hard to spot weld because of the mill scale, but we ground that off of both sides of both prices with a flap wheel, and I'm still getting no penetration on the weld, it gets orange but them pulls apart easily by hand.
Anything I can do, or just switch to mig?
