Sharpen Tungsten Electrode
To avoid Electrode contamination, dedicate a fine grit grinding wheel exclusively to Electrode grinding.
WARNINg! TO pREVENT SERIOUS INJURy: Some
Electrodes may have materials added to them that are
hazardous to breathe. Wear a respirator and ANSI-
approved Safety goggles when grinding an Electrode.
1. Shut off the welder and wait until Electrode
and Torch have cooled enough to handle.
2. Remove Back Cap. Pull Electrode from front
of Torch. (Pulling it from rear will damage
Collet and create burrs on Electrode).
3. If Electrode has dulled or been otherwise
contaminated, use pliers or a suitable tool to
grip the Electrode above the contaminated
section and snap off the end of the Electrode.
4. Lightly press Electrode tip
against the surface of
the grinding wheel at an angle.
Rotate Electrode tip until a
blunt point is formed.
Note: Grinding direction must be
parallel to length of Electrode.
5. The conical portion of the ideal
tip will be 2-1/2 times as long
as the Electrode diameter.
6. Re-insert Electrode into Collet with tip
