Copper Tig welding.

If it took 150 amps for 1/8in and 300amps for 1/4, does than mean I can do 1/16 with 75amps. Yes this is a real question.

I played with some 1/16-inch wall pipe this morning. 120-amps seem to work fine to get a puddle going, but again it didn't take long before I was backing out of the pedal.

I wonder what kind of amps you'd need if you preheated. Do they have a flux cleaner for Copper?

Very nice!

What's that? Educate me!

Thats exactly what I was thinking about welding. Got to put together a moonshine still you know.

Looks good. I don't think I would have bothered ordering proper welding rods though. With how cheap I am, I would have to try it with scrap electrical wire before spending anything.

From what I have read, copper wire has a tendency to make a porous weld. Havent tried it so dont know if thats true or not. If true, I think the copper wire wouldnt be a good choice if you where going to do any structual or pressurized pipe welding. For what ever I would be doing, it would be ortamental so I suspect the copper wire would do just fine. Now just where did I put those moonshine still plans.

I've been following this. Though I have never tried it (on my welding "bucket list") regular copper wire is pretty much pure copper, so it should not cause any problems in a copper weld.... Protected from oxidation by the insulation too, at least to some degree...

It works perfect bud, trust me

They may not. I've never needed to weld copper. But in brazing and soldering they have it. I would figure that would be something that might help.
