  • Syncrowave 250 problems

    I am having trouble wiith a Syncrowave 250...when I ease off the pedal to slowly back out of aluminum welding the arc just stops..I thought it might be the pedal so I bought another and that did not help.

    Are you saying you have no throttle? In other words, is the pedal acting like a momentary switch, where it's either ON or OFF, but there's no difference in the amperage between half-pedal and floored?

    If so, check your panel. For aluminum welding, you should have:

    - AC Polarity
    - Process: TIG
    - Amperage: Remote
    - Output: Remote
    - Start Mode: HF Cont.

    Have you checked/gapped the HF points?

      You are correct, it is just off and on and no difference between half pedal and floored. all of the settings are correct. I have not checked the gap..what should it be?

        I'm no tech by a long shot, but it sounds like your OUTPUT control isn't functioning properly for whatever reason.

        I believe point gap should be .008" (and I think, based on the manual for my 330A/BP, that a larger spark gap will cause you to have a more aggressive/effective HF arc starting) but my gut says the points ain't your problem. Can't hurt to check, though, I guess.

        Maybe Cruizer or somebody else who knows what they're talking about (not me) will be along here soon...

            Need a little more info, and the serial# Does the pedal control the arc at all? Are you in remote for contactor control and weld control. do you have a torch water cooler.

              Sounds just like mine. Are you saying the pedal works as an on off switch for contactor control, but does not adjust current at all, ie if the panel is at 100, you can have 0 or 100. If the panel is at 111 you can have 111 or 0 ? ( nothing in between?)

                      I have the same problem with my syncrowave 250(ser#KA 910615). No amperage control, I have to set it at the panel. Tried a new reastart and no differents? Wonder if its the circuit card control? Cruiser do you have any ideas what I should look for? Thanks.

                        I had the old factory pedal and a off breed pedal that I was trying..I borrowed my friends pedal off his Syncrowave 200 and it solved my problems. I bought this welder a couple years ago and didn't try both pedals...I am sorry for not explaining that earlier..those two pedals have been thrown away.

                          When the foot control on SW 250 went wonky I found it had some shorted wire in the cable runing from the panel to the control case.....might be worth a look.

                            Another case of poisoning the well?
