  • Syncrowave 250- Help with remote foot pedal

    During the summer I was using my Syncrowave 250 to weld aluminum and my foot pedal worked fine, in the fact that it would run the amperage up and down as it should. I started another job and now the pedal will only work at the max amperage I set the machine. It will engage at my set max amperage but, when I start letting up on the pedal it does not decrease the amperage at the end of my weld. Anybody had any similar probs?

    It is VERY common for the pedal cable to get pinched/stretched or otherwise damaged-----shorted/open.... leading to similar symtoms...

    the first thing I would do is to connect a known good pedal and see how the machine behaves...

    also make sure that all of your front panel switches are properly configured...

      Good idea but, I don't know of anyone within my area with a foot pedal, is there any way I could ohm the pedal and determine if it is working correct.

        Your pedal is likely a RFC-14 or RFCS-14... there were a few variations/styles..

        here is where you can download the manual... will need your style/serial number

        http://www.millerwelds.com/service/o...uals.php?model

        could do a visial inspection.. looking for visible damage to the cable or broken wires at the connector or at the pedal..
        but beware..many times it can be defective but look good..

        would check continuity on the individual wires in the cable.. as well

          Checked continuity, and resistance, the pedal seems to operate fine. When you depress pedal it goes from 10 ohms to 0 on one set of pins and, when you let up it goes from 0 to 10 ohms on the other pin using the middle for common. Continuity reads good on all wires.

            where are you located??

            could always take your pedal to your LWS or another weldshop and try it on one of their machines..

            remember... a damaged cable may work fine in one position and be inop in another

            those things lead a tough life... pedals get dragged around by the cable.. get stuck and yanked..sharp steel falls on the cable ...mashes..smashed.. pulled etc etc...
            solder joints at the 14pin get fatigued and fail ..
