Got a new HF spot welder for Father's day today. No more plug welding rails which I have become good at, but no more. Its a bit tricky with a small gas wirefeed.

I tried using tubing, 1/2 inch soft copper from the hardware store was too springy. I bought a same length of 3/8 inch and slipped it inside. It works well. I reused the tip of the HF spot welder, but if I were to do it again I think I'd use MIG tips.

Better would be a length of Type M hard copper tubing, if you have a plumbing supply in your town they should be able to fix you up.

I found a guy that sells that same tong on another forum for less than I could I could make it for.
I bought one and it works, which was a surprise to me.
But this tong really works; AK Hunter1 says it is hard copper tubing with heavy copper cable inside. And it has a
MIG welder tip that is replaceable.
He sells extra tips too. Here is the link.

One thing about aluminum. As it gets hot it expands and then shrinks when it cools.Make sure you check your connections for tightness once and a while.

I know this is a very old thread, but Type K copper is thicker...used for water supplies and such. If making a tong using cable and tubing, use the Type K.
