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.
