    No pics here of pure copper, but if you click the link in my sig line, you will see some copper-nickel welds.

    Pure copper may not get quite as much color to it when tig welded.

    Hey Engloid something is out of whack with your link. Some HTML glitch somewhere. I just get a bunch of gobblygook computer lingo on that link. Or is it just me? I havent seen seen those nifty welds in a while. Very inspiring.
    Cheers,

    Some browsers dont like when there's no "html" at the end of the URL.

    thanks for the compliment.

    I do some copper.

    It takes all the heat you can give it. I was doing some 1/4" copper a few weeks ago with my Dynasty 200 and the machine was seriously under-powered.

    I finally got a decent puddle up by clamping the part so the weld area was off the edge of my weld table and by using minutes of MAPP torch preheat at full output. I also had to use 100% helium. Still, I was coaxing the weld together, not welding normally.

    The puddle itself is very, very wet, and the liquid as thin and runny as water. You weld fast with Copper, and there's little surface tension to the puddle. Have your rod ready, and be prepared to use a lot of it!

    My welds usually turn completely black as they cool. So much of the copper gets so close to welding temperature near the bead I think I'd have to have an Argon box to keep the part looking clean. But it polishes wonderfully, and the black comes right off with modest brushing.

    You do get a rainbow of colors, but I usually see those during pre-heat. I have to get the piece well beyond solder temperatures to have any hope of drawing a puddle with my lowly Dyn200 on thicker material. It's pretty wild to watch a 200A Helium arc focus on a single spot for even 20-30 seconds and not draw any evidence of a puddle at all! But, that's 1/4-inch copper for you...

    Post TIG welding Copper

    Tig welding copper is very hard if you never did it before. Because some race car frames were soldered be easy and use solder.

    Seems like ANY welding is hard if you've never done it before!

    Some race car frames are soldered!! I don't think so!!!
