To connect PT-21AMX torch to the console, connect the power cable of the
torch to the ‘‘NEG’’ terminal and pilot arc cable to the ‘‘POS’’ terminal of the unit
using pilot arc adaptor (p/n 19497 (4485843) - supplied with spare parts kit). A
separate remote control switch cable is required for connecting to the switch
receptacle on the console.
The front end of the torch contains a gas flow check valve that acts in
conjunction with the circuitry provided in the power supply. This patented
system provides a safety interlock preventing the torch from being accidentally
energized with high voltage when the heat shield is removed and the torch
switch is accidentally closed.
6. Tighten heat shield fully to hold the parts in firm contact with each other and
to the torch head. “Fully” means at least 3/16" (4.8mm) rotation after electrode
seat contacts electrode holder.
5. Apply a thin film of lubricant p/n 17672 (0558000443) to O-ring p/n 488157
(4485841).
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. 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.
