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 the electrode wire is fed via the MIG Torch (Consult the electrode wire 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 wire, welding current at any one setting would vary according to the type of electrode wire
in use. The operator should use the welding current range values as a guide, then finally adjust the current
setting to suit the application.
