3. Install the electrode insulator (21373) onto
electrode holder assembly (21332) and then thread
electrode (21150) onto the electrode holder
assembly. Assemble electrode firmly by hand. Do
not use wrenches or pliers. These three parts
combined are the electrode assembly.
4. Install nozzle onto the electrode assembly by
inserting small shoulder on electrode insulator into
nozzle's rear opening. Place nozzle and electrode
assembly into the heat shield as shown in page 6.
If front end of the torch is facing down as normal in
a setup, the nozzle and electrode assembly can be
stacked in the heat shield and then assembled to
the torch. Be sure to use proper heat shield and
nozzle combination as noted in page 18.
5. Apply a thin film of lubricant (17672) to O-ring
(488157).
