SHIELDING GAS CONNECTION FOR TIG TORCH KIT
A Shielding Gas Bottle is not included with your Eastwood ARC 80 but is necessary while TIG welding. A Shielding Gas Bottle can be
bought at most local Welding Supply Stores. Eastwood recommends the use of 100% Argon shielding gas when TIG welding Steel and
Stainless Steel.
After connecting your Shielding Gas Regulator, the gas fl ow rate needs to be adjusted so that the proper amount of Shielding Gas is
fl owing over your weld. If there is too little gas fl ow there will be porosity in your welds as well as excessive spatter, if there is too much
gas fl ow you will be wasting gas and may affect the weld quality.
• Place the Eastwood ARC 80 in its dedicated area or on a welding cart.
• Secure your Shielding Gas Bottle to a stationary object or mount to your welding cart if it is equipped to hold one so that the cylinder
cannot fall over.
• Remove the cap from the Shielding Gas Bottle.
• Thread the CGA-580 fi tting of the Argon Shielding Gas Infl ow Line into the female fi tting on the Shielding Gas Bottle.
NOTE: Do not use White Tefl on Tape on this connection as it is a tapered thread and does not require it, if you have a leak check for burrs
or dirt in the threads. If the leak persists, use gas type sealing tape.
• Tighten the fi tting with a wrench till snug, do not over tighten.
PREPARING TO TIG WELD WITH TIG TORCH KIT
TORCH ASSEMBLY/DISASSEMBLY
Assembly:
• Select a Collet body that matches your
Tungsten diameter size and thread it into
the front of the Torch.
• Select a Collet that matches your
Tungsten diameter size. Insert the
Tungsten into the Collet and put the Collet
and Tungsten back into the Torch (Fig D).
• The Gas Shielding Nozzle size should
be changed according to shielding gas
requirements for the material being
welded. Thicker materials require more fl ow. Select the correct Gas Shielding Nozzle and thread it onto the Collet body.
• Install the back cap to lock the Tungsten in place. Always make sure the Tungsten protrudes 1/8" to 1/4" beyond the
Gas Shielding Nozzle (Fig D).
Disassembly:
• Make sure the welder is turned OFF and unplugged.
• Remove the Back Cap from the Torch.
• If there is a Tungsten installed in the torch pull it out of the front of the Torch.
• Slide the Collet out of the Torch.
• Unscrew and remove the Gas Shielding Nozzle.
• Unscrew and remove the Collet body.
