TITLE/ PRODUCT NAME: PT-19XL 2-Piece Nozzle Assembly
RATING:
_
(Action is Required) (Potential Problem)
_
(Action is Optional) (Enhanced Product)
_
(Unrestricted) (Restricted Distribution)
PRODUCT SERIES/ MODEL:
PT-19XL and PT-19XLS Torch and 2-Piece Consumable Parts
SERIAL NO:
All
SUMMARY:
To attain the usable life of the 2 pc nozzles, the heat generated during plasma cutting must be
removed from the nozzle tip. The PT-19 torch is designed so the heat is conducted through the
copper tip into the liquid cooled nozzle base. To get efficient heat transfer the tip and base must
be assembled correctly.
OPERATIONAL IMPACT:
Consumable life improvement.
ACTION:
Refer to the Figures of the reverse side.
1 Nozzle tip and nozzle base must be assembled before installation in the torch
2 Firmly tighten the nozzle tip into the nozzle base (100 inch-pounds of torque)
a) Two methods are acceptable:

X_ General Distribution _ _ Business Confidential
1)
Two Wrench Method
While holding the nozzle base with one wrench (1 5/16-In.) use a second wrench
(13/16-In.) to secure the tip into the base 100 inch pounds.
Note
100 inch pounds is approximately equal to the force that can be manually
(by hand) applied with a 6 inch long [open end] wrench.
2) One Wrench Method
Securely mount the nozzle base into a stationary fixed holder (such as a vice)
with threads accessible being careful not to crush the base. Thread the tip and
tighten it to approximately 100 inch pounds.
Reminder
A thin coating of silicone lubricate (PN-17672) is applied around the
periphery of the nozzle and "0" rings before assembly.
3 Drop the assembled 2-piece nozzle into the nozzle retaining cup with the nozzle base pointing
toward PT19 body.
4 Screw this assembly onto the PT 19 body and tighten "hand tight".
a) If using a PT 19XLS, install the secondary shield parts last.
NOTE
The diffuser is installed with the notches pointed toward the PT19 body. The shield and
shield retainer are assembled "hand tight".
Additional information may be found in the maintenance section of the PT 19XL /
PT I9XLS instruction manual.
