Thread: ac/dc alum weld

  1. #1

    Default ac/dc alum weld

    I have a lincoln tombstone ac/dc welder. What would be the best way for me to weld aluminum. I have an old airco 300 amp water cooled tig torch and a homemade water cooler I made from a bucket and pond pump. I been running on dc- under 180 amps with no overheating problems. Could I tig on dc+ without killing my pump or would the power backfired into the water causing problem? Or just aluminum stick it?

    Dr. welding,

    You could try scratch starting tig on AC but it would be easier to use DC and alum stick electrodes.

    Theres no RELIABLE way to weld Aluminum with what you have.

    Once you add on a high frequency box, you can try. You still won't have amp control though.

    Learn from my mistakes. I tried the same thing with the same unit. In the end, it's cheaper to buy a dedicated ACDC tig welder. You will not gett good results.

    As for stick welding Aluminum, try it on a test piece first. It's a hot, fast milky mess that burns through really fast and is hard to control.
