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

    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.
    Never carry gasoline in your car trunk. If you do, atleast use some sort of container.

    Wink Re: Copper Tig welding.

    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...

    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.
