SHARPENING THE TUNGSTEN
To avoid contamination of the Tungsten and ultimately the weld, it is imperative to
have a dedicated grinding wheel used for Tungsten grinding only. A fi ne grit standard
6" synthetic stone grinding wheel on a bench top grinder is suffi cient or specifi cally
designed Tungsten Grinders are available.
• Shut off the welder.
• Make sure the Tungsten and Torch are suffi ciently cooled for handling then loosen
and remove the Back Cap then the Collet (Fig D) and remove the Tungsten from
the FRONT of the Torch only. (Removing from the rear will damage the Collet).
• If the Tungsten is used and the end is contaminated, use pliers or a suitable tool
to grip the Tungsten above the contaminated section and snap off the end of the
Tungsten.
• Holding the Tungsten tangent to the surface of the grinding wheel, rotate the
Tungsten while exerting light pressure until a suitable point is formed (Fig E).
• The ideal tip will have the length of the conical portion of the sharpened area at
2-1/2 times the Tungsten rod diameter (Fig F).
• Replace the Tungsten in the Collet with the tip extending 1/8"-1/4" beyond the
Gas Shielding Nozzle, then re-tighten the Back Cap (Fig G).
TIG WELDING WITH TIG TORCH KIT
IMPORTANT NOTE:
These instructions are intended only to provide the user with some familiarity of the
Eastwood ARC 80. TIG welding is a highly complex procedure with many variables. If
you have no experience with TIG welding; it is extremely important to seek the advice
of someone experienced in TIG welding for instruction, enroll in a local technical
school welding course or study a comprehensive how-to DVD and obtain a good
quality reference book on TIG welding as there is a moderate learning curve necessary
before achieving profi ciency in TIG Welding. Before attempting to use this unit on
an actual project or object of value, practice on a similar material as there are many
variables present and settings required when TIG welding different metals such as
steel and stainless steel. It is also strongly recommended that the user adhere to the
American Welding Society guidelines, codes and applications prior to producing welds
where safety is affected.
• Turn the Power Switch to the ON position (Fig H).
• Slowly open the gas cylinder valve.
NOTE: Always open valve fully to avoid shielding gas leakage.
• Adjust the gas regulator to 15-20 cfm.
• 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, fi le or grind a bare area to achieve a good ground to
assure safety.
• Use a dedicated stainless steel brush or fl ap-disc to clean the areas to be
welded. Do not use the brush or fl ap-disc for any other purpose.
