Arc voltage
For systems other than the PowermaxEdge bundle, you can use arc voltage from the power
supply to activate a torch height control. To do so, you must supply an 18 AWG (1.0 mm2),
single pair, unshielded cable rated for 300V or greater. All work must be performed following
applicable national or local codes.
1. Disconnect power from the power supply.
2. Remove screws that attach the power supply cover to the chassis. Remove the cover.
3. Feed the cable through the strain relief, shown below, at the rear of the power supply.
WARNING
ELECTRIC SHOCK CAN KILL
Disconnect electrical power before performing any maintenance.
All work requiring removal of the power supply cover must be
performed by a qualified technician.
