OPERATION
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. 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.
4.02 Front Panel
A. Process Selection Switch
Switches between Lift TIG and Manual Arc Welding
modes. Refer to Section 3.06 Setup for Manual Arc
Welding and 3.07 Setup for TIG Welding.
B. Power ON Indicator
The Power ON Indicator illuminates when the ON/OFF
switch is in the ON position and the correct mains
voltage is present.
C. Over Heat Indicator
The welding power source is protected by a self
resetting thermostat. The indicator will illuminate if the
duty cycle of the power source has been exceeded. If
the Over Heat light illuminates wait for the Over Heat
light to extinguish before resuming welding.
D. Welding Current Control
The welding current is increased by turning the Weld
Current (A) control knob clockwise or decreased
by turning the Weld Current (A) control knob anti-
clockwise. The welding current should be set according
to the specific application. Refer to application notes
in this section for further information.
E. ON/OFF Switch (located on rear panel-not
shown)
This switch controls the Mains Supply Voltage to the
Power Source.
