TUNGSTEN GRINDING
Shape by grinding longi-
tudinally (never radially).
Remove the sharp point
to leave a truncated point
with a fl at spot. Diameter
of fl at spot determines
amperage capacity. (See
below).
The included angle
determines weld bead
shape and size. General-
ly, as the included angle
increases, penetration in-
creases and bead width
decreases.
Use a medium (60 grit
or fi ner) aluminium oxide
wheel.
You can also sharpen the tungsten electrode using our
chemical tungsten sharpner part # ckstigsharp.

TORCH HEAD ASSEMBLY
1. The electrode to use is the red tipped "2% thorium
tungsten" 1/16" in diameter.
2. Make sure the Tefl on heat shield is in place.
3. Locate the matching size Collet and Collet body.
4. Drop the Collet, slit-end down, into the Collet body.
5. Screw assembly into the torch head, heat shield side,
and tighten fi rmly.
6. Install a Gas cap, screw into place seating the cup
against the Tefl on heat shield.
7. Insert tungsten electrode, prepped end fi rst, thru the
torch head, Collet and center hole of the Collet body.
8. Allow tungsten electrode to extend past the cup ~ 3
times the electrode diameter.
9. Screw Backcap into torch head and tighten fi rmly.
