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.
