1.POWER SWITCH - Input line switch turns input power ON or OFF, as indicated by the on or off sta- tus of the front panel displays.

2.POLARITY SWITCH – The 3-position rotary power switch has detente positions for DC-, AC and DC+ selections for the Electrode output welding polarity.

3.MODE SWITCH – The mode switch allows vertical- ly positioned selection of the two machine welding modes. The selected mode is indicated by a lit col- ored panel light which permits viewing the machine setting from a distance:

3.a STICK mode (Top position) –Red panel light

WARNING

ELECTRIC SHOCK can kill.

•When the Power Source is ON in STICK mode the Electrode circuits of both the Stick and TIG torch cables are electrically HOT to Work.

------------------------------------------------------------------------

•The CC Stick mode may be used for general pur- pose stick welding (SMAW ) within the capacity of the machine. The capacity is too limited for arc air carbon (AAC) gouging.

•In this mode; the output terminals are activated electrically HOT, gas flow is not activated and HOT START and ARC FORCE levels are fixed, or Advanced Panel selectable (See Internal Set Up controls), with no front panel adjustment.

3.b TIG mode (Bottom position) – No panel light.

•When the Polarity Switch is set to AC, the TIG mode provides continuous high frequency to stabi- lize the arc for AC TIG welding.

Hi-Freq. turns on after preflow time with the arc start switch closure, and turns off when the arc goes out* after the arc start switch opens.

* Arc voltage and current are sensed to determine if the arc is established or out.
