    Additionally, I had asked a local weld repair shop if it mattered at all where (which tap) I hooked the generated third leg to on the machine. Their response was that maybe if I took into...

    Hey John, thanks for asking. I just now finally have a clamp on meter being delivered in the next couple days so I've not tested any current draw, but it seems to be running quite well on the big...

    Thanks for the reply Mr Kamp. Indeed the 302 is now running seemingly fine on the 20hp RPC without issue. I have yet to do any real current/voltage measuring but will in time. It does seem to be...

    I've seen on a few of the RPC manufacturer sites, that welders (resistive loads) are ok, and apparently are fine. But here again, I'm looking for more info on the subject in both regards.

    Running the CP302 off 20hp RPC

    So I am now successfully welding with the Miller CP302 off of my 20hp RPC.
    I know quite a few guys are running their welders off of RPC's in some fashion or another. I have also heard from some...
  6. Hey john, thanks so much. I will have more time...

    Hey john, thanks so much. I will have more time to play with it later today. Honestly, I need to figure out how to wire in some run caps to balance the legs a little better. From what I read its just...

    FYI those settings above of 25v and almost 50 on the wfs with 035 wire and 75/25 mix were on 1/4" plate.
    Does this seem to be lagging/underpowered to you? I'm assuming ocv open current voltage...

    Ok so yes I'm at low inductance setting, middle tab. Also using .035 wire, and 75/25 gas. I ran a nice bead this evening with the machine set to 25v and just under 50 on the wfs. Wish I could post...

    Bill, yeah all that measuring is easier with a helper around, which I don't currently have. I also don't have a voltmeter with a memory. Been putting off a Fluke 376FC purchase for far too long. Soon...

    As for the inductance setting, I *think* its the factory setting (not sure if thats low or high?) But wires #25 and 26 are hooked to the middle and top tabs. The very bottom most tab is folded...

    Jjohn,
    When you say "make sure my phases are in order" I'm not quite sure what you mean.
    This welder (I thought) should run thrme same regardless of where I have T1/T2/T3 hooked up to,...

    Bill, thanks for asking. There is no contactor. Only 3 SCR's. So no clicking.
    Anyhow, I made a few adjustments and tightened up some very loose connections and got it welding.
    I am wondering...

    Also, if it means anything, dc amperage on the machine read just under 100 when running a bead. Can you gleen anything from this?

    John, about to drive somewhere but serial is LA261232. So apparently the NO WELD OUTPUT LIGHT stays on until you pull trigger and strike an arc?
    I got it running. Somewhat.
    It is slightly...

    Ok thanks jjohn
    I'm still on the fence about this. I hooked up to my RPC for first time last night and I'm getting the dreaded NO WELD OUTPUT warning light.
    FM fan motor runs, and there is...

    Hi jjohn,
    How many 60/5 capacitors are needed for the HK conversion on CP302?
    My best guess is two total caps, but I'm just not sure. Have yet to see a materials list. Thanks.

    In case anyone can help out, I should mention I have only tried the 230v tap setting.
    I have not yet tried the 200/220v tap setting and wondering if that is not only safe to try, but might...

    Welder hookup to RPC

    I have a 20hp RPC, and currently hooking up a Miller CP302. I will post measured, no load voltages below for each leg of the RPC yo GRD, and also across LEG-LEG.
    My question is this. Does it...

    Well I'm with jjohn 100%. I much prefer transformers over inverters.
    jjohn, thank you so much. I was thinking the contactor was unique to this machine based on the picture google turned up via...

    I believe they quoted
    Fan motor - Miller p/n 238626 and
    Contactor - Miller p/n 252907

    How does one come upon a CP weldsr for $23? Not $20, not even $25. $23 was the magic number of bills you had in your pocket?
    Anyhow, I just scored a CP302 and I'm going to run it on my 20hp RPC....

    jjohn, just typed a reply only to have it disappear.
    Anyhow, I replied back in other thread.
    I appreciate thr 65mfd recommendation. I was unclear on that. I already have bleed resistors and a...

    jjohn, thanks for the link. I'll definitely check it out. One of my main questions is in regards to capacitors. I think oul filled, motor run are preferred. Over 370v AC and as far as mfd rating I'm...

    Is anyone here located in or around Atlanta GA, who might be willing to help me with a CP300 conversion?
    I know this rewiring is PHYSICALLY easy to perform, but I just don't have the electrical...
