Has anyone tried mig welding copper? I dont have access to a tig welder but i do have a mig. i was wondering if you could use electrical copper wire in a mig welder, i have 100 meters of one mill solid core copper wire and was thinking about winding it onto a empty drum and trying to weld with it. ideas anyone?

I'm not sure if there is a specific copper roll to might copper but I know with tig that using just copper filler rods on my bubbler, it was very hard to flow. I had to pump the amps into it and it was fine line between it flowing and burning a massive hole all the way through. I ended up getting actual copper filler rods which had a minute amount of silicone in it. That helps it flow at a lower temp.

So my guess is that you'll blow holes in everything as you will have to use such high amps in order to get the filler wire to flow.

Copper as a very good conductor i think you have to heat up what you are welding cold copper is going to distort. With the stainless mig welding there is a lot of talk about different gases and penetration.

Thanks guys, it was just a thought, I wont waste my time trying it now. I don't want to blow holes in my nice bit of 4 inch.

Strongy, i have a ss/copper 3'' combo.
Have gone thru all the bull with trying to weld with my MIG, was even going to get a TIG... changed my mind...gas/filler rods..Blah Blah..$$$$
Got a bloke to TIG my 3'' ss col to the ferrule and silver braze the ss ferrule to the copper 3''...he really new what he was doing... all for 2 bottles of 40% neutral...Bargain... some stuff (big diameter builds) are better done by pros.
Good luck...Ken
