  • ALT vs XMT on thin plate

    Since the ALT 304 is out of production and the XMT 350 is it replacement. Do I have to buy two machines to be able
    to MIG 24ga. And what other than the XMT 350 should I buy? I'm stuck with single phase and trying to find something that produces an arc like my Trailblazer, which has really spoiled me!

    Do you need this unit for mostly thin material??? Why the heavy duty machine?
    The XMT 350 will do a nice job on the thin material but will still have a hard time running a continuous weld bead on that thin material without burning through. Now, the little Passport 180 is designed for thinner material and so is the MM 350 or MM 350P

      I already have a rc12, wc24 ,15a and tb301. I just looking for a power supply that would do it all. Not that I do a lot of thin stuff. Just trying to get feed back from those with working knowledge.

        ahhh 10-4

        It would do it but you would be better off spotting or small stitching.

          I used a TB 301G for all my mobile work except TIG. There I used a Dynasty 200DX powered by the TB's aux power. As far as the arc is concerned the ALT and XMT totally blow it away!

          I had and XMT 304 for several years and currently have an ALT 304. Yes the ALT volt/amp curve is better designed to accomodate thin material. I have run continuous beads on 22 gauge and spotted 25 gauge. It is an "Auto-Line" unit and has the lower end V/A pc board. Other than that is is the XMT 304 equal. The XMT 304 has "Auto-Link" and starts about 30 amps higher on output than does the ALT.

          The XMT and ALT are both great units and I would not hesitate to own either of them as a single multi-process DC machine. Even on 1 phase they will produce max output at about 50% of the 3 phase rated duty cycle. Take a good look at the XMT 350 which is a close replacement for the ALT 304.
