Solution for Brazing Electrodes of Spot Welding Gun

I agree just what I thought GA

What I suggest is that you machine the horns of the welder to clamp the electrodes by tightening a screw. Then make new electrodes out of RWMA Class 2 copper (chrome-copper). They will outlast pure copper electrodes by a significant margin. Depending on what you are welding, there may be even longer lasting materials than Class 2, but that's a good start. One thing for sure; you don't require silver brazing rod.

Dear Welderman,

Thanks for your reply, what brazing rod would you recomend for doing the same.

Reread the OP; sentence (2) specifically mentions brazing rods.

"What I suggest is that you machine the horns of the welder to clamp the electrodes by tightening a screw. "

Dear Welderman , it would be great if you could elaborate this setup.Do you mean some thing like this.

What you have illustrated is perfectly acceptable. There is no reason to solder or braze the electrodes into the horns. Alternate methods for installing electrodes include tapered electrode shanks (commonly morse taper) into tapered holes in the horns and threaded electrodes into threaded horns. The version you illustrated is fine, and has the advantage of being able to adjust electrode extension.

The attached photo illustrates a horn with a conventional electrode clamped with two screws. It also shows a threaded electrode and a tapered electrode. The clamp works well and is capable of adjusting the electrode extension. The two pipe plugs on the left can be removed for water cooling of the electrode. In all three cases, no soldering or brazing of the electrodes is required.

The first thing I noticed was that the tips are not parallel. I hope there is a reason for it?

The spot welders I've used, have a threaded copper stud with a HEX on it.

That thing looks silly. Remember no electricity UNLESS the work and the electrodes are in place.
