  • Mig Welding without a spool gun

    Hello everyone, I am new here. I have a question about mig welding aluminum. I have a Hobart 140 mig welder. Can you weld aluminum without a spool gun with this welder? Is there a spool gun that can fit this welder? I asked Hobart and they just said they don't offer a spool gun for aluminum welding for the Hobart 140.

    Thank you

    Technically, it is possible. It will be very difficult, and is not recommended, especially since it will be extremely limited in the range of aluminum it could have the power for, even with a spoolgun. What aluminum are you hoping to weld?

      Some is 1/8" thick and I also have 1/4" thick aluminum.

        It will only be used as cover. They will not be holding any pressure or force but it own weight.

          Aluminum wire does not feed well through a 10 foot whip, and by everything I have read the 140 is a bit on the weak side for power to do aluminum....
