Help on connecting powermax65 to a portable cnc

admin

HiI bought a portable cnc and a powermax 65 plasma cutter,  the cnc was previously connected to a Jackle plasma (German brand) , i have an interface cable with 6 spades ends but i have no idea how to connect them in the cnc side. The previous wires were connected inside the machine in labeled places as follow: Arc start 1Arc start 2Arc -Arc+DC 24 +DC 24 - In the hypertherm side  i have 3 ,4,12,14,13,5,6Could you please help me to find out the right combinations.Thank you in advance

Reply:The Powermax65, if equipped with a machine torch and a CPC interface port (circular plastic connector on rear panel of Powermax65) has input and output signals for plasma on (pins 3 and 4), arc transfer (pins 12 and 14) and divided arc voltage output (pins 5 and 6). The details for these connections are in the installation section of the Powermax operators manual.You have not provided enough information for us to help you make the connections.....we would need the input / output requirements for the particular cnc machine that you have. There are over 100 manufacturers of cnc machines for use with plasma cutters....the interface connections vary. I suggest referring to the wiring suggestions from the cnc machine manufacturer, then compare them to the information in the Powermax 65 operators manual.   Jim Colt    Hypertherm

Reply:Thank you guys for your replies, the machine is chineese one assembled in France (called suprazy)  I got it second hand without documentation, I found some docs in internet so i could find a wiring diagram but still not clear for me. - The wiring diagram

-the picture of the controller without any wiring

- pictures of the 06 wires i need to combine withe hypertherm interface cable.

Reply:Hi againFinallay the CNC plasma cutter worked, it was a missing dividing box that i had to buy. Now I am using the Hypertherm cut chart for the plasma setting but I had to add about 10 volts to the recommended voltage otherwise the torch collides with the plate ,i.e. I put 138 volts to cut a 4 mm plate with 65 Amp instead of the 127 from the chart . do you have any idea about the roots of problem . (the torch and consumables are new)thanks in advance
Reply:I think the root of the problem is that Kublai Khan was successful in overthrowing the Chinese in the 13th century.
Reply:Set the torch up with a feeler gauge to exactly  1.5 mm (.06"). Do a test cut (at least 100 mm long) at book cut specs with the THC off. Read the divided voltage out of the voltage divider. Do another identical test cut and read the digital readout on the height control. Do another identical test cut and read the raw arc voltage from the Powerboard on the Powermax65 (negative terminal J28, positive J26). Depending on the ratio of the voltage divider, divide the Raw voltage from the power board by that amount (so if the Raw voltage from the test cut was 127 volts, divide by 50 (if the divider is set to 50:1) and you will get 2.54 volts from the divider. If this is correct, then the output from the plasma and the divider are correct....so there likely is a calibration issue within the height control system. Be careful as there is very high voltage present inside the power supply.If there is no procedure (with your height control system) for calibration, then simply set all of your voltages for cutting higher by the amount of difference you see between the raw voltage and the digital readout. Remember that voltage does not matter, the physical height during steady state cutting is what is important. Set the voltage to whatever it takes to maintain the correct physical height. The voltage settings in the Hypertherm manual are correct under laboratory conditions at book cutting specs for height, speed, amperage, and with new consumables. What happens in the field often changes the voltage to height ratio. The best height control systems auto calibrate before every cut cycle by sampling the voltage at the beginning of each cut and locking on that voltage. This takes the voltage variable out of the operators hands and let's the software and electronics set it correctly every time.    Jim Colt    HyperthermLast edited by jimcolt; 05-02-2017 at 07:16 AM.
