4.01 Overview
Conventional operating procedures apply when using the Welding Power Source, i.e. connect work lead directly
to workpiece and electrode lead is used to hold electrode (Consult the electrode manufacturers information
for the correct polarity). 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 finally adjust the current setting to suit
the application.

1. Amperage Control (Welding Current)
The amperage control knob adjusts the amount of welding current delivered by the power source. The am-
perage is increased by turning the amperage clockwise or decreased by turning the amperage control knob
anti-clockwise. The amperage should be set according to the electrode type and the specific application. Refer
to application notes in this manual for further information.
2. Power Indicator
The power indicator is illuminated when nominal 240V AC mains power is applied to the power source and
the ON/OFF switch located on the rear panel is in the ON position.
