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 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 dis-
abled.

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.
