How to Sharpen Tungsten for Stainless Welding

The way tungsten is sharpened can mean the difference between a sound and poor tungsten inert gas (TIG) weld. Unlike aluminum, tungsten for stainless steel requires a sharp point with a long taper to direct the arc from the TIG welder to the surface of the stainless steel. Using a tungsten sharpener places the correct taper and tip on a tungsten electrode without the off center grind associated with using a bench grinder.

Instructions

        1
        Set a tungsten grinder on a level surface. Turn on the grinder. Allow it to reach the recommended grinding speed.

        2
        Turn the size dial -- located on the front of the grinder -- to the size of the tungsten electrode you need to sharpen.

        3
        Slide one end of the tungsten electrode into the hole located on the size dial. Push the tungsten toward the grinder until the tungsten begins to spin. Release the tungsten. Allow it to spin in the grinder for one minute.

        4
        Turn off the grinder. Remove the tungsten electrode from the size dial. Inspect the point at the end of the electrode. Turn on the grinder and reinsert the tungsten if the end of the electrode does not form a sharp point.

        5
        Repeat the process to sharpen the other end of the tungsten electrode.

Tips & Warnings

    Protect your eyes by wearing safety glasses when using a tungsten grinder to sharpen a tungsten electrode.
