  • I'm having a problem with my Syncrowave 180, anybody ever seen this?

    I've been the proud owner of my Syncrowave 180 for 4 or 5 years now and I ran into trouble with it. I was welding some 1/4" steel @ about 120 amps, nothing too demanding. I welded off and on for about 10 minutes and then walked away from it for a while. I came back to it and that's when the trouble started.

    When I hit the foot pedal I get absolutely nothing. No arc, no gas. When I switch the machine from TIG to Stick (but with the TIG torch still hooked up), I get gas flow while I'm switching it, and when it is switched I can scratch an arc with the tungsten.

    I checked all the cable connections, everything is good. I powered down the welder and unplugged it for a minute or so, plugged it back in and that didn't help.

    I thought it might be the foot pedal. I tore it apart, it is a 5 wire pedal and there are two components in it. A limit switch and a 1K Ohm potentiometer. I checked the limit switch for continuity, it is good. I checked the resistance on the pot, it changes smoothly from 0-1K ohms across wires 1 and 2, and it changes smoothly from 1K-0 ohms across wires 2 and 3. It seems like this is right.

    Anybody ever have a similar problem or have any other ideas? My next step is to investigate inside of the welder but I don't really know what to look for.

    I knew eventually we would get to the root of the problem; you're against knitting!

    Whats your problem?
    The whole deal could have been over with post 4

    I dont let things drop, until I have the information to satisfy my curiosity. Not in my nature.

    The problem with the written word is that some people take things the wrong way, like you for instance, if this is "nauseating" to you then maybe you should join a knitting forum.

    Judging by your post I dont think that you have understood the posts at all.
    There has not been any arguments just questions and answers, then you come up with a post to inflame the situation !

    Good grief!

    Hahaha, and just when everyone thinks they have it all figured out....we'll change everything back!

    As far as my welder goes, thanks Bob, you were right. It was a short between two wires (we do call them wires here right? Not hoses or rope or something?).

    Right, he was just calling electrical components by names which they are not to "simplify" things for me.

    Wheeww, now I get it. Thanks for clearing that up. In the future it might be easier to call switches switches, and relays relays. My electronics and electrical technology courses would be pretty confusing if my prof started using terms interchangeably. It would most likely result in a lot of non working microprocessors and PLCs.

    I bought some five conductor cable and rewired the foot pedal, everything is fine now.

    I'm embarrassed that I didn't check that more thoroughly before I posted but there was no visible damage to the cable and I freaked out and thought the worst. I guess that's why they say that the wires are the most overlooked electrical component.

    I just signed up to answer your question regarding what we call relays and switches in Canada. Let me assure you we most definitely know the difference between the two.
    You can be certain that those individuals working on Canadian aircraft are very much Professional, and able to discriminate between the two on schematics, and in disscusions amongst themselves.
    You can fly with confidence
    Have been thinking about you joining up just to clarify that you guys know the difference between relays and switches.
    Were you just "passing by" and stumbled upon the posts?
    Whats the odds on that?

    I prefer to fly QANTAS !

    Cheers

    I was just interested to know why you refer to a simple switch as a relay, have never heard of that terminology before.

    Cheers

    I called it a relay as 2 pins in the pedal close to tell the machine to start up.
    For me its symantics, I was trying to make it simple for the guy to understand

    Yes this is a mico switch even made by Mico switch
    OK so you guys call a switch a relay sometimes (in simple terms)
    I figured that was the case just had to confirm it, bit strange though.
    The OP I think was a bit confused when you actually referred to the switch as a relay.

    circuit diagrams don't differentiate between a micro switch and a electromecanical relay.
    This worries me, do you have different symbols.
    Surely it would show a coil and contacts, or does it just show it as a set of switch contacts?

    Because they don't know any better??

    Nope the electrical portion of the Releco is a relay, the mechanical test push button is a switch.

    Same as a positioner table hitting an magnetic switch and reversing itself, no physical force really, just a polarity pickup, or even an electric eye picks up a discrepancy in its field of vision, or encoders that is also a switch for wave form production.
    An IGBT is a ultra fast switch, as are transistors, mosfets, scrs and such, all electrical switches.

    Its all the way you look at the problem to get the job done.
    Nope it is a relay, that is it's main function. Some relays have a mechanical actuator, "flag", led's whatever but for all intents and purposes they are still a relay with a coil and some contacts.

    IGBT's, fet's, micro's are indeed switches, they are not relays

    My main point is why do you guys refer to a micro switch or a trigger switch as relays?? This is the third time I have asked the question and all I get is a question in response to a question.

    Just curious as to why?
