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+).

4.Place the electrode in the electrode holder.

5.Turn the power switch to “ON”.

WARNING

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