Fault code 0-30-1 means the nozzle and electrode are stuck together and cannot create an arc. Possible causes may include:
Low gas pressure
Gas restrictions
Gas leaks caused by a damaged torch lead or regulator
Hose diameter impacting flow rate
External filters may be constricting the gas flow, verify all flow rates for components feeding the power supply
Gas restrictions
A deformed or damaged swirl ring is stopping electrode movement
