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.
