Replace the Nozzle Assembly
Assemble the Nozzle Assembly
1. Liberally lubricate the two O-rings (#044031) on the sleeve and the two O-rings
(#044135) on the body assembly with the silicon lubricant provided (see Figure
3-2).
2. Insert the sleeve wrench over the small diameter end of sleeve and turn to lock in
place.
3. Insert the sleeve into the body assembly by pushing and turning the sleeve
wrench clockwise (cw) until the sleeve is completely inserted.
Mount the Nozzle Assembly to the Torch
1. Remove one of the thumb screws on the nozzle assembly and slide the nozzle
assembly up onto the torch (see Figure 3-1).
2. Adjust the torch and nozzle assembly together until you locate the groove in the
torch body when looking through the threaded thumb-screw hole.
Note: If your torch does not have a groove in the body (older style torches) push
on nozzle assembly until it touches the insulating sleeve.
3. Replace the thumb screw and hand-tighten. Tighten the two other thumb screws
in place.
4. Liberally apply a 1/4-inch band of silicon lubricant around the inner (threads) and
a 1/4-inch band around the outer circumference of the shield cap (see Figure
