WELDING IN STICK MODE
1. Put the electrode holder and cable quick connect
plug into the electrode output receptacle. Turn
clockwise until tight. Connect the work clamp to the
work piece.
2. Set the TIG/STICK switch to “STICK”.
3. Set the Polarity Switch to the weld mode desired for
the type of electrode being used (most commonly
DC+).
4. Place the electrode in the electrode holder.
• In Stick Mode the output terminal
and electrode will be electrically hot
whenever the power switch is
turned on.
-----------------------------------------------------------------------
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 disabled.

Tungsten electrodes are classified as follows by the American Welding Society (AWS):
Pure ..................................EWP ........green TRI-MIX OF ELEMENTS.............EWG.........gray
+1% Thoria .......................EWTh-1 ...yellow
+2% Thoria .......................EWTh-2 ...red
+2% Ceria.........................EWCe-2...orange
+1.5% Lanthana ...............EWLa-1 ...black
+0.15 to 0.40% Zirconia....EWZr .......brown
Ceriated Tungsten is now widely accepted as a substitute for 2% Thoriated Tungsten in AC and DC applications.
