Forms a clean, balled endwhen heated and providesgood arc stability for ACwelding with a balanced orunbalanced squarewave orsine wave.

Performs well in DC weldingand arc starting at low-current settings, and offersexcellent performance in ACprocesses.

Provides excellent arcstarting, arc stability andre-ignition, and is lessprone to tip wear.

Substitute for 2% Thoriated.Similar characteristics to1.5% Lanthanated with bet-ter arc starting, arc stabilityand less tip erosion.

Combines the best of allalloying elements andprovides excellent arcstability in AC or DCwelding.

Triad ™ Tungsten Grinder

©2011 Weldcraft Printed in U.S.A.

Triad™ Tungsten Grinder (TTG Plus)This tool provides operators with theversatility and accuracy needed to preparetungsten for both orbital welding and hand-held applications. Its grinding, cutting and facing capabilities eliminate the needand cost for additional preparation tools.Plus, it features the most robust, reliablemotor available in the marketplace.

Includes a sturdy powder-coated steelcarrying case, medium-finish grindingwheel, electrode holder, Torx T20 screw -driver and mounting plate to convert to bench model. (Refer to Index Sheet AY 6.0 for more information.)

TIG Tip

Note: Do not use wheel for other jobs or tungsten can become contaminated and cause lower weld quality. Use pointed tungsten when welding AC or DC with most inverters.
