Note:

The cover on the machine interface receptacle pre-

vents dust and moisture from damaging the recepta-

cle when not in use. This cover should be replaced if 

damaged or lost.

Installation of the machine interface cable must be 

performed by a qualified service technician. To install 

a machine interface cable:

1.   Turn OFF the power and disconnect the power cord.

2.   Remove the machine interface receptacle’s cover 

from the rear of the power supply.

3.   Connect the machine interface cable to the pow-

er supply.

6.2.5.  CNC Socket Diagram
The CUT power supplies are equipped with an op-

tional, factory installed, four position voltage divider 

that is designed to be safely connected without tools. 

The built in voltage divider provides a scaled down 

arc voltage of 20:1, 30:1, 40:1, and 50:1 (maximum 

output of 18 V). An optional receptacle on the rear of 

the power supply provides access to the scaled down 

arc voltage and signals for arc transfer and plasma 

start.

Note:

The factory presets the voltage divider to 20:1. To 

change the voltage divider to a different setting, refer 

to the section on the next page.

The factory installed internal voltage divider pro-

vides a maximum of 18V under opencircuit condi-

tions. This is an impedance protected functional 

extra low voltage (ELV)output to prevent shock, 

energy, and fire under normal conditions at the 

machineinterface receptacle and under single 

fault conditions with the machine interfacewir-

ing. The voltage divider is not fault tolerant and 

ELV outputs do not comply withsafety extra low 

voltage (SELV) requirements for direct connection 

to computerproducts.
