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.
