Set-Up For Mma (Stick) And Gtaw (Tig) - Boss ARC 140 Operating Manual

4.0

SET-UP FOR MMA (STICK) AND GTAW (TIG)

Conventional operating procedures apply when using the welding power source, i.e. connect work lead
directly to work piece and welding cable is used to electrode holder. 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, and then finally adjust the current setting to suit the application.
WARNING:
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 2:
Remove any packaging material prior to use. Do not block the air vents at the front or rear of the
Welding Power Source.
