1. Turn the Power Switch/Circuit Breaker to the on position.
2. Slowly open the gas cylinder valve.
NOTE: Always open valve fully to avoid shielding gas leakage.
3. Depress gun trigger switch or foot pedal and adjust the flow regulator.
(Refer to Data Chart for actual settings).
4. Grounding is very important, place the Ground Cable Clamp on a clean, bare area of your work
piece as close to the welding area as possible to minimize the chance of shock. Scrape, wire
brush, file or grind a bare area to achieve a good ground to assure safety.
5. Use a dedicated stainless steel brush or flap-disc to clean the areas to be welded. This is
particularly critical on aluminum as a microscopic layer of oxidation can prevent an arc and
actually produce a poor-quality, contaminated weld. Do not use the brush or flap-disc for any
other purpose and keep one for steel and one for aluminum.
6. Make sure all your safety gear is in place (Welding Mask, Welding Gloves, Non-Flammable
Long Sleeve Apparel) and the area is completely free of flammable material.
7. Although it is a matter of developing a personal style, a good starting point for best results
is achieved by holding the tip at a 75° angle. Hold the Filler Metal Rod at a 90° angle to the
Tungsten Tip (FIG. J). Never allow the Tungsten Tip to touch the welding surface or material
rod. Doing so will quickly destroy the tip and contaminate the weld. If this happens, remove
the Tungsten and regrind the tip. It is best to hold the Tungsten 1/8" from the surface.
8. With your Welding Shield and all safety gear in place, depress the foot pedal or trigger and
practice "Forming A Puddle" with the Tungsten Tip. Once you become familiar with this step.
Practice the "Dip and Pull" technique with the Filler Metal Rod and Torch. "Dip and Pull" is
the practice of forming a puddle, moving the torch while maintaining the puddle and adding
filler rod metal to the puddle by "dipping and pulling" as you go; being careful not to allow the
Tungsten to contact the puddle or rod.
9. Keep in mind that you MUST let the shielding gas flow over the weld after releasing the
trigger or pedal. Failure to do so will allow the welded area to oxidize compromising the weld
integrity.
10. Constantly be aware that TIG welding quickly generates heat in the work piece and torch.
Severe burns can quickly occur by contacting hot metal pieces.
11. When done, shut off the Power Switch and close the Shielding Gas Tank valve completely.
