    Default Powermax 45 Hand Torch to Machine Torch



    No there is no cone switch.. One less thing to go wrong. Cut the 3 wires off Blue-cone-switch,
    purpple-torch-fire and orange-common slid a piece of heat shrink tube over wires..

    Default Handtorch to Machine torch



    You do not need pin-6-purpple wire Torch fire wire for hand torch.
    So i moved pin-6 to pin-8..

    Connecting Pin 7-orange and pin 8 is what changes the machine to machine-torch mode.

    I know this was hard to do, to take a brand new torch And tear it apart, but just could not see paying 650 for a machine torch.
    There was no modes done to the machine..
    Know the machine interface plug (on back of machine) pins 3 and 4 fires the torch.. fn perfect..

    I didn't have to cut any wires. I took the rear plug apart and pulled pin 6 out and put it in pin 8 slot. Then take the torch handle apart, remove the trigger switch (not the red trigger) and put a wire shunt across the 2 pins and tape it up. Put the handle back together and you have a torch that works like the machine torch. If you ever want to convert it back, just move pin 8 back to 6 and put the switch back in.

    As for the plasma post, if you're talking about Sheetcam, I just use the MAch3 plasma post. Seems to work pretty good.

    Default hand to machine

    Very good detail on your conversion. Do any of you know if this is the same for the PM 85 torch?

    The schematics I have don't specify either the 65 or 85. However, the interface kit , part # 223036, to install the CPC port wiring and voltage divider board is the same for both the 65 and 85. Since the CPC port is wired the same in both machines, the torch wiring would have to be the same. Also, the torch leads and receptacles are the same for the 65 and 85.

    The good thing is that you can always put it back if it is different but I don't think it is.

    Thanks willy for the quick response....so everything in this post is for the 65 or 45? I have a 85 and almost have completed the hand to machine conversion but the safety is the last hang up.

    The good thing about moving pin 6 to 8 and shunting the trigger switch is that it can no longer be used as a hand torch. It can only be fired from the CPC port. Also, the other safety switches are still in place so if the consumables (cap, nozzle, etc) are loose or missing, the torch won't fire.

    The plug pinouts are 1 & 2 is the pilot arc, 5 is the cap sense safety, 6 is the start lead, 7 is common, 8 is the mech torch pin. Looking at the plug end with the guide slot at 12 o'clock, the pins count clockwise. You should have 1,2,5,6, & 7.

    My extra torch (15 deg) is ALWAYS bolted to the table like a machine torch so I don't have to worry about someone using it as a hand torch.

    Good luck

    Pin #11 is labeled AMP0. I have it also. I believe it is for torch current but I don't know for sure. The only pin I touched was 6 and everything works great.
