Did you have any problems with your serial port and THC? I'm frustrated as hell with mine.

Not sure, doesn't really matter.....just make that bushing on the lathe and use something smaller than the tap drill...

xalky: Are you using an everlast plasma also?
Actually got it all working pretty well....just have the "torch ok" signal jumpered, but other than that i got it working good.

No, I have a longevity machine. You can read my build log in this forum to get some details. I had a hell of a time getting serial ports working.

This may help, this is from Ray at Everlast.
I will try to answer what I can. Not knowing what controller you have I can’t tell you exactly how to hook it up.
Pins 1 and 2 are the torch switch, this activates the plasma cutter.
Pins 9 and 10 “OK to Move” are a N.O. contacts, sometimes referred to as “Dry contacts” this is a non electronic switch that closes when the pilot arc transfers to cutting arc. Sometimes referred to as “Arc OK”. Sometimes the controller uses this sometimes not.
Pins 5 and 7 are the undivided arc voltage, used by some controllersto adjust the height of the torch. This is the actual cutting voltage it is run through 2 -100K resistors to prevent arcing at the connector plug. Some controllers can use this as is, Depending on the impedance of the input. CandCNC controller and Torchmate cannot use this as is,most others can.
Pins 4 and 6 are the divided arc voltage this is adjustable by a jumper on the board to either 1/16 or 1/50 the arc voltage, and also used by some controllers for torch height control. CandCNC can use this in 1/16 mode. The 1/50 voltage is hard to detect due to the low voltage and interference from the Hfstart. IE: 200 volts arc voltage would be 4 volts, if the torch voltage dropped 5 volts to 195 the divided voltage would be 3.9. so usually the 1/16 setting is preferred, the default setting is /50.
Pin 3 is what some controller manufactures refer to as “Ground” this is connected directly to the work piece lead, which is actually a positive voltage. If the controller has a pin for ground this is probably the pin to use.
Tips, don’t connect anything directly to the output terminals or leads. Don’t connect anything from the controller to the chassis of the cutter, especially a ground lead. Don’t install any kind of converter or divider inside the machine. This usualy causes a fire.
Hope this helps, and feel free to call me if you have any questions. If I’m on the phone please leave a message and I’ll call you back. I don’t ordinarily return calls from caller ID with no message, as I don’t want to interrupt someone at work.
Yup. Thats the exact same pinout as my longevity machine. Tom at CandCNC didn't know what to do with the divided arc pins. I tried wiring them right to the Bladerunner THC control module and I fried it. Wish I'd seen your post 2 days ago. Tom at candc is helping me out. Good guy.
I am getting ready to order a THC from CandCNC. I'm probably going to order the Everlast 60C plasma cutter, but I'm making sure I can get it to work properly before I order it. I have several Everlast Welders and they have been very good to me.Originally Posted by xalky
My question is how should the THC be wired to work properly?
you're gonna have to order the rav01 , which is an external voltage divider with the non standard connector, I believe its called the nsc01 connector. It's about $45 additional for the whole package to make it work with the everlast.
You should start a new thread for your build...I don't wanna hijack johns thread.

Incorrect xalky....all everlasts with the CNC port have an internal voltage divider. The DTC works ok using it....(and i say "ok" as in "ok"...not perfect) but i cant get the arc-ok signal to work properly....
--John
Are you using your internal voltage divider?
John I have a purchased a CandCNC LCTHC and I am trying wire it up to my Everlast PP50 plasma cutter. I have read your description and some of the other comments. Would you be kind enough to send me a photo of where exactly you connected the torch control in the plasma machine? Also did you ever figure out the issue with the ark ok? Is it something with your machine or inherent to these machines? Any other wiring help would be mcuh appreciated since I don't want to fry anything and electronics is not my forte.
rayzsurfer: I gave up and bought a hypertherm.
However, i had the everlast working good, just wire the arc-ok wires to a switch. This way you can just leave the switch closed and it will run good, if you want it to stop just open the switch.
