TUNGSTEN PREPARATION:

END PREPARATION:
DCSP (EN)
General Purpose:
Flat:
1/4 to 1/2 x Diameter Taper:
2 to 3 x Diameter
ACHF
General Purpose:
Ball:
Maximum 1 x Diameter Ball tip by arcing on clean metal at low current DCRP (EP) then
slowly increase current to form the desired ball diameter.| GRINDING PREPARATION:
Use a 60 Grit or finer aluminum oxide wheel Shape tungsten by grinding logitudinally, never radially. Remove sharp point to leave a truncated point with a flat spot. Diameter of flat spot determines amperage. The included angle determines weld bead shape and size. Generally, as the included angle increases, penetration increases and bead width decreases.| EXTENSION INSTRUCTION:
STANDARD PARTS
General Purpose:
3 x Diameter from end of cup. GAS LENS PARTS
General Purpose:
3 x Diameter from end of cup. Maximum extension: 6 x Diameter from end of cup.
