The welding power source is protected by a self re-setting thermostat. The indicator will illuminate if the duty cycle
of the power source has been exceeded. If the FAULT light illuminates wait for the FAULT light to extinguish before
resuming welding.
A. POWER Indicator
The POWER Indicator illuminates when the ON/OFF switch is in the ON position and the correct mains voltage is present.
B. FAULT Indicator
The welding power source is protected by a self resetting thermostat and over primary current protection devices.
Welding can not take place if the FAULT Indicator lights up continuously or is flashing.
Thermostat Protection
If the Fault Indicator lights up continuously then the duty cycle of the power source has been exceeded. Leave the
power on and wait for the Fault Indicator to extinguish before resuming welding.
Over Primary Current Protection
If the Fault Indicator flashes on and off then the primary current into the main transformer has been exceeded. Have
an Accredited Thermal Arc Service Provider inspect then repair the welder.
