Sort by:

  1. Can this machine tig weld aluminum??

    1 answer

    1. The WELD-PAK 180i MP DV is a DC-only TIG machine, which means it cannot TIG weld aluminum. TIG welding aluminum requires AC output and the optional K5341-1 Magnum spool gun.

      Helpful?

  2. Is this machine capable of welding aluminum

    1 answer

    1. The welder is capable of welding aluminum. You would need the Magnum 100SG spool gun, item 44732 for welding aluminum.

      Helpful?

  3. How small of an generator can I use with this welder

    1 answer

    1. Use at least a 3‑kilowatt generator for 120‑volt operation or a 6‑kilowatt generator for 230‑volt operation. It must be a clean 60‑hertz inverter generator with a stable 90–250‑volt RMS output, and you should allow extra capacity. Aim for about 4 kilowatts for 120‑volt use or 6 to 8 kilowatts for 230‑volt use to handle welding surges and duty‑cycle demands.

      Helpful?

  4. Does this have a spot stitch mode?

    1 answer

    1. The welder does not have a spot stitch mode.

      Helpful?

  5. What is this welders duty cycle?
