SECTION 4:
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.
