This document provides information on common fault codes, descriptions, and solutions for a power supply. Fault codes range from 0-12 to 0-99 and cover issues like low gas pressure, unstable power input, hardware faults, over/under temperatures, torch connection errors, and internal communication failures. Most faults can be addressed by checking gas connections, power sources, consumables installation, and allowing the unit to cool. Fault 0-99 requires service by a qualified technician.

code LED LED icon 0-12 Low input gas pressure On Off • Adjust the gas inlet pressure as needed. or unstable gas pressure: Warning (the system continues to operate) 0-13 AC input unstable: Warning Blinks Off • Correct the power source. (the system continues to (3 Hz) operate) 0-19 Power board hardware On On The inverter shuts down and does not fire protection. One or more again for several seconds. If the fault is power board hardware faults caused by electrical noise, the fault clears (or noise) detected. in a few seconds and the machine operates normally. If a true fault continues to occur, the 0-99 fault code appears on the operator screen. Service personnel can access the fault log in the service screen to identify the major fault. 0-20 Low gas pressure On On • Check the input gas supply. • Adjust the gas pressure to the acceptable range using Manual mode. See Section 4, Operation. 0-21 Gas flow lost while cutting On On • Restore the gas inlet pressure and restart the power supply. • Check the torch lead for leaks or kinking. 0-22 No gas input On On • Connect the gas source and restart the power supply.
