What to do if GAS LED is OFF on my ESAB Welding System and Communication Fault shows LoP?

If the GAS LED is off and the Communication Fault shows LoP, it could be due to several reasons: * The gas supply might not be connected. Ensure the gas supply is connected to the unit. * The gas supply might not be turned on. Make sure to turn the gas supply on. * The gas supply pressure might be too low. Set the air supply inlet pressure to 120 psi and adjust the leads length to match the actual length being used. * There may be failed components in the unit.
