Accessing raw arc voltage (Powermax65/85 systems)
To access raw arc voltage, you must install the strain relief (part number 008279) in kit number 228711. You must also
connect an 18 AWG, 2-wire, non-shielded cable similar to OLFLEX ® 190 (601802) in the length needed to extend
between the power supply and the CNC or other equipment plus approximately 60 cm (2 feet) of cable to connect
inside the power supply.
1. On the end of the cable to be connected inside the power supply, strip the outer jacket 7.6 cm (3 inches). Then
strip 1.3 cm (0.5 inch) of wire insulation off of each wire.
2. Crimp an M4 (#8) insulated ring terminal on the end of Wire #1 (negative lead) and an M6 (1/4 in.) insulated ring
terminal on the end of Wire #2 (positive lead).
3. Use a drill with a 19/32 drill bit to drill out the access point on the rear panel. Be careful not to damage internal
components.
