too high; shorted torch body; consumable parts worn out.

2-1

Missing Phase

Blown fuse, Broken or loose connection on power cable
Inverter(s) not configured correctly for input voltage;
Poor power quality (brownouts, dropouts);
Input power capacity / wiring too small causing voltage
drop; broken or loose power cable connections.

output; Shorted pilot regulator (chopper); CCM voltage
sense (J6) wire open or disconnected.

2-6

Primary over current or
imbalance fault

Over current or imbalance detected in inverter primary
circuit, remove power to reset; defective inverter; voltage
surge.

2-7

Unexpected current

Current >20A in work or pilot leads before pilot ignition;
Possible shorted torch; Defective current sensor.

2-8
