SECTION 4:
OPERATION
Conventional operating procedures apply when using the Welding Power Source, i.e. connect work lead directly
to work piece and electrode lead is used to hold the electrode. The welding current range values should be used
as a guide only. Current delivered to the arc is dependent on the welding arc voltage, and as welding arc voltage
varies between different classes of electrode, welding current at any one setting would vary according to the type
of electrode in use. The operator should use the welding current range values as a guide then fine tune the welding
current to suit the specific application. Refer to the electrode manufacture's literature for further information.

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
If Fault indicator lights up continuously then that is an Overcurrent Condition and needs to be serviced by an
Authorized Thermalarc Technician.
