SETUP

WARNINg!  TO pREVENT SERIOUS INJURy:  
protective gear must be worn when using the 
Welder; minimum shade number 10 full face shield 

(or welding mask), ear protection, welding gloves, 

sleeves and apron, NIOSH-approved respirator, 
and fire resistant work clothes without pockets 
should be worn when welding.  Light from the 
arc can cause permanent damage to the eyes 
and skin.  do not breathe arc fumes.

After practice welding on scrap,

 stop, 

and check your progress.  Perform 

Strike Test according to 

Strike Test on 

page 20.

  After making any necessary 

adjustments, continue to weld 

while 

carefully following the DUTY CYCLE 

guidelines as explained on page 14.

8.  Hold TIG Torch in one gloved hand and 

TIG Rod in other gloved hand.  

9.  Specific Welding Techniques:

  

TIg HF Start 

 

•  Hold Torch 

away from the workpiece

 

the same distance as 1 to 1.5 times the 
diameter of the Tungsten Electrode.

Note:

  To prevent Tungsten Electrode contamination, 

do not touch Torch to workpiece before arc initiates.  

•  Press Foot Pedal down slowly until arc 

initiates.  Then, press Foot Pedal down all 
the way to reach maximum amperage.  Let 
up on Foot Pedal to lower amperage.

  

TIg LIFT Start 

•  Touch Tungsten Electrode to workpiece.  
•  Press Foot Pedal down 1 - 2 seconds.  

Then, lift Electrode off workpiece the same 
distance as 1 to 1.5 times the diameter 
of the Electrode, to initiate the arc.

•  Press Foot Pedal down all the way to 

reach maximum amperage.  Let up on 
Foot Pedal to lower amperage.

  

TIg pULSE Welding

•  After arc is initiated, Welder will 

pulse between Peak Amperage and 
Background Current at a rate of 2 PPS.

•  Peak Amperage Time is 50%. 

Background Current is 30% of 
Peak Amperage Current.

NOTE:

 Maintain a constant distance between the 

Tungsten Electrode and the workpiece: between 
1 and 1.5 times the diameter of the Electrode.

10.  When welding puddle is hot enough, tilt torch 

backward about 10-15 degrees from vertical and 
move it back slightly. Add TIG Rod material as 
needed to the front end of the weld puddle.

11.  Alternate between pushing the torch/weld 

puddle and adding the TIG Rod material. 

NOTE:

  Back the TIG Rod off each time the Electrode 

is advanced, but do not remove it from the gas shield. 
This prevents oxidation from contaminating the weld. 

12.  When finished welding, release the Foot Pedal, but 

keep Torch on weld puddle until gas flow ends. 

13.  Set TIG Torch down on nonconductive, 

nonflammable surface away from 
any grounded objects.

14.  Turn the Amperage Knob to the lowest 

setting, then turn the Power Switch off.

15.  To prevent accidents, after use:

•  Allow Welder to cool down.
•  Unplug Welder’s power cord from outlet.  
•  Remove Ground Clamp from workpiece or table.
•  Disconnect TIG Torch, Ground 

and Food Pedal Cables.

•  Close gas cylinder’s valve securely, 

remove regulator and replace cap.

•  Disconnect Gas Hose from Welder.
•  Store and secure gas cylinder.
•  Clean, then store Welder and its accessories 

indoors out of children’s reach.
