Over Temperature Indicator
This welding power source is protected by a self resetting thermostat. The Over Temp indicator will
illuminate if the duty cycle of the power source has been exceeded. Should the Over Temp indicator
illuminate the output of the power source will be disabled. Once the power source cools down this
Over Temp indicator will go OFF and the over temperature condition will automatically reset. Note that
the mains power switch should remain in the On position such that the fan continues to operate thus
allowing the unit to cool sufficiently.
16.
Gas Inlet (MIG mode only)
The Gas Inlet connection is used to supply the appropriate MIG welding gas to the unit. Refer to section
5.09 set up details.
WARNING
Only Inert Shielding Gases specifically designed for welding applications should be used.
