Haha I had a project at work about a year ago welding copper and used the same wire!! Thought I was the first to figure that out. I also was surprised that it took almost 100 amps to weld copper that was thinner than 1/16!!

@floridarobot It is really easy to do. Just like aluminum.
-
@mustie1 The welder was set for DC Tig. Running straight argon at 10 psi.
Thanks for asking....

I have a small project for my brewery I'm looking to have TIG welded like that since I'm trying to avoid brass in the system if I can. It's 3" copper tubing with 1/8" wall. What kind of amperage do you think I might need for this job? My buddy has a TIG, but wasn't sure it had enough current to do the job, and we haven't dine any tests with scrap yet. The longest weld will be 18" long, so I figure that will soak up a substantial a mount of heat.

@Bonaireboy85 If his machine can run about 100 amps you should have no problem at all. Defenatly do a few test runs on some scrap first but you should be fine at about 75 to 85 amps to start. When you are welding it should be in the 55 to 65 range i think.
Hope that helps....
Thanks for posting......

could you show more of the finished product such as wire wheel it or clean it up so we can see the weld? also could you show if that was a fill and cap and root pass hot pass fill and cap and stuff like that, like a practical aplication type copper weld. i enjoyed the video, thanx.

@secondclasscitezen I will try. You just have to remember that I am in front of the camera not behind it.

@jorgencream Now that is a damn good question.
Sadly I do not have an answer for it. I would guess because the battery was dieing on the camera and we were hurrying to get the video shot.
Ok, redo time!!!
