Set-Up For Smaw (Stick) And Gtaw (Tig) - Thermal Arc pro-life 250s Operating Manual

PRO-LITE 250S

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.
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.
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.
