  • Need help, Dialarc 250HF, WC-II/Spoolmatic II won't work? Why?

    I recently picked up a old Dialarc for some TIG work, had a WC-II and Spoolmatic II included in as a package although it wasn't hooked up as they used it for TIG only. Anyhow, I wanted to hook it up so its available incase I would need it. Hooked everything up as per the manuals that were included in the deal and I got nothing at the spool gun. I got line voltage to the on/off switch on the WC-II but I can see where all the wires go in the bundle after that. I do not see anything out of ordinary, nothing looks burned/smells. Fuses are ok? Anything I am missing? I am betting its something simple I am not seeing. ThanksTyler

    You didn't try running it with the HF on did you? If you didn't - DON'T!

    What weld output polarity? Should be DCEP (reverse).

      Yes, DCEP............No on the HF. Ideas where to look first?

        If you measure where the gun trigger connects you should be able to measure 24VAC. This is at the terminal strip loactions #21 and #22 (wires #32 and #51 inside the WC2 control box). See if you have this and let me know and we can proceed from there.

          Not really made for a CC machine, however the contactor control is always A,B, on the dialarc, whether it's on the 5 pin, or 2 wire plug. The control WC-2 runs off 115 volts, so can use the power source or wall plug. Never the less no wire will work other than a dual shield
