5.0 SET-UP FOR SMAW (STICK) AND GTAW (TIG)
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 electrode. Wide safety margins provided by the coil
design ensure that the Welding Power Source will withstand short-term overload without adverse effects. 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 electrodes, 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.
WARNING 7
Before connecting the work clamp to the work
and inserting the electrode in the electrode
holder make sure the Primary power supply is
switched OFF.
CAUTION 3
Remove any packaging material prior to use.
Do not block the air vents at the front or rear
or sides of the Welding Power Source.
CAUTION 4
DO NOT change the Weld Mode or Weld
Process Mode until after POST-FLOW time
has finished.
