Ok I have a Powermax 1250G3 and was going to put it on my new CNC table I just bought, the table came with a powermax 600 with a THC 300 in it, I'm going to sell the 600 and have to remove the THC board out of the 600 and put it in the 1250.
with that said can i just leave the board in the conrol box on the table and run a cable to the back of the 1250 where the connector is aready? and where can I get the male plug that mates to it??
Thx Railmen

Re: 1250 G3
Since I do not know what brand and model cnc table and the THC board that you have.....I cannot really answer your question.
On most machines there is a "voltage divider" board that has to connect to the raw DC arc voltage inside the plasma...this voltage can be as high as 300 volts DC. The divider board then reduces this voltage to a safe level (generally less than about 15 volts, and sends it to the Torch Height Control electronics for height control (arc voltage) feedback. The divider board is produced by the height control manufacturer.
If the height control on your machine can accept a 50:1 voltage divider ratio, and your Powermax1250 is of new enough vintage (if it has pins in place on holes 5 and 6 on the CPC interface plug it has an internal 50:1 divider), then all of the interface wiring can go directly through the CPC interface cable. Otherwise....you will have to re-use the voltage divider that came with the original system....and it will have to be hardwired to a couple of screw terminals on the main power board inside the 1250.....Raw DC voltage. We cannot supply he RAW DC voltage on the CPC interface plug as the voltage level exceeds safety standards from CSA.
My son has a business that produces some cables that will interface directly to the Hypertherm systems....making them easier to interface. If you can supply me some more information I can help you source the correct plug and cable...also can help you with the correct Raw arc voltage connections.
So..make and model of the cutting machine and the board (THC) you are referring to would help. Also, keep in mind that the CPC interface connections are only usable with a machine torch. If you are planning to use a hand torch on the 1250 for machine use...the start input will not function for safety reasons. Feel free to email me directly at jim.colt@hypertherm.com

Re: 1250 G3
Ok here is a new question, since selling all my plasma cutters today,now I am going to buy Powermax 65 with 50' hand and 25' machine.
What will it take to hook it up to my THC 300 controller
Sorry if I'm short on info, as I'm new to this game of CNC

Re: 1250 G3
If your Powermax65 is equipped with the CPC port (round plastic interface connector on rear panel) then the interface can be accomplished with a cable that plugs into the CPC. If it does not have the CPC it is available as a field upgrade kit from Hypertherm.
Not knowing what type of interface is accepted by a THC300 controller.....usually all of the interface signals are available on the CPC port, There are two connections for plasma start, two connections for arc transferred output (also known as "arc good", "ok to move"), and there is a divided arc voltage output with settable ratios of: 21.1/1, 20/1, 25/1, 30/1 and 50/1 depending on the input voltage needs of your THC.
If your THC300 requires raw arc voltage on the input...that will require two separate wires that connect directly on screw terminals on the main power board in the Powermax65.
