1. Determine initial settings from TIG Data Table based on material 

thickness.

2. Place 

WELD PROCESS   

      switch to the TIG  (left)  position.

3. While holding the 

PRESET

        button, adjust the 

CURRENT

knob to set desired weld current in the upper digital display window.

4. Touch  the  tungsten  electrode  to  the  workpiece  momentarily  to 

establish the arc. Adjust the welding current as needed for the 

desired puddle control.

Note: The

 WIRE SPEED          

knob has no effect in TIG  mode.

1. Determine initial settings from Stick Electrode Data Table based 

on electrode  type and diameter.

2. Place the 

WELD PROCESS

      switch to the STICK (right)  position.

3. While holding the 

PRESET

        button, adjust the 

CURRENT

knob to set the desired weld current in the upper digital display 

window.

4. Strike the electrode and start welding. Adjust the welding current as 

needed for the desired puddle control.

Note: The

 WIRE SPEED        

 knob has no effect in STICK mode.

Shielding gas flow rate

15 - 25 cfh 

When the WELD PROCESS switch is set to TIG or STICK position, the electrode will be electrically “

HOT

”.

 When the WELD PROCESS is set to the MIG position, depressing the gun trigger will cause the wire 

electrode to become electrically “

HOT

” and will start the feed motor to feed wire. 

Do not allow the electrode to touch the work until you are ready to make a weld.

POLARITY CONNECTION GUIDE

1. Determine initial settings from MIG Data Table based on wire 

type, diameter, material thickness and shielding gas.

2. Place 

WELD PROCESS

      switch to MIG (center) then press  

PRESET 

        button.

3. Turn the  

WIRE SPEED

        knob to set desired speed in the 

upper digital display window.

4. Turn the 

VOLTAGE

       knob to set desired voltage in the lower 

digital display.

5.  Pull gun trigger and start welding. Fine tune wire speed and  

volts as needed for desired arc characteristics.

MIG/FCAW SET-UP

Note 1: MIG 3/8" and above setting data indicates multi-pass weld sequence with proper joint preparation required.

Note 2: FCAW above 1/2" setting data indicates multi-pass weld sequence with proper joint preparation required.
