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.
