7.Once the electrode is burned down move the elec- trode quickly from the weld to extinguish the arc.

8.Turn the machine off and remove the stub by open- ing the jaws of the electrode holder and insert a new electrode.

Note: The welded work piece and electrode stub are hot after welding. Allow them to cool down before touching or use pliers to move. Always make sure the welder is turned off before set- ting down the Electrode Holder.

TIG WELDING (TUNGSTEN INERT GAS WELDING)

This machine is capable of direct current (DC) TIG welding which is suitable for hard metals such as steel, stainless steel, copper and brass. The TIG process is good for welding thin materials requiring very good cosmetic appearance with low heat input and low spatter. TIG welding uses a tungsten elec- trode which delivers electrical current to the work piece by way of an electric arc. Unlike stick welding in which the electrode is consumed in the arc, the tung- sten electrode is not consumed. Instead filler metal is added to the weld by manually dipping a filler rod into the weld puddle. TIG welding requires a higher skill level than stick welding and practice is required to master the technique. For best results a TIG welding class is suggested or obtaining a book on how to TIG weld.

TIG welding also requires 100% Argon shielding gas to shield the arc, preventing porosity in the weld. This is different than stick welding which has a coating on the electrode to produce its own shielding. In addition, a gas regulator, a manual gas valve TIG torch, torch parts kit, torch adapter and filler metal are required.

Refer to the accessories section of this manual for an appropriate optional TIG torch, parts kit and torch adapter. A gas regulator, filler metal and a bottle of shielding gas are readily available from a welding gas distributor.

See Figure B.7 shows the basic TIG welding setup:
