the positive portion may also cause the electrode to overheat at high currents causing “tungsten spitting”. The negative portion of the AC wave offers no cleaning action but concentrates more heat on the work. The AC waveform of the Square Wave TIG 175 optimizes cleaning and heating of the work. The result is the capability to weld through the complete range of 12 to 175 amperes in AC TIG or DC- TIG requiring only one electrode, a 3/32” 2% thoriated tungsten.

WELDING IN STICK MODE

1.Put the electrode holder and cable quick connect plug into the electrode output receptacle. Turn clock- wise until tight. Connect the work clamp to the work piece.

2.Set the TIG/STICK switch to “STICK”.

3.Set the Polarity Switch for the type of electrode being used (most commonly DC+).

WARNING

In Stick Mode the output terminal and electrode will be electrically hot whenever the power switch is turned on.

4.Place the electrode in the electrode holder.

5.Turn the power switch to “ON”.

6.Adjust the Current Control to the desired amps.

7.Strike an arc and weld.

NOTE: When the TIG/STICK switch is set to “STICK” the output is always on when the power switch is on. A remote control has no effect on the welding current and the gas flow and high frequency TIG arc starter are dis- abled.
