3.2 PRE-OPERATION SET-UP
The pre-operation set-up procedure should be followed at
the beginning of each shift:
WARNING
Disconnect primary power to the system before
disassembling the torch, leads, or power supply.
1. Check the torch for proper assembly (see page 27).
Make sure the proper torch parts are installed:
Standard Shield Cup (Ceramic) .......................... 9-5617
Standard Shield Cup (Phenolic) ......................... 9-5781
Castle (Crown) Shield Cup.................................. 9-5694
Drag Cup ................................................................ 9-5712
Gouging Cup ......................................................... 8-5128
Standoff Attachment (Use with 9-5781) ............ 9-5799
Standoff Attachment, Short (Use with 9-5781) . 9-5780
Heat Shield (For Gouging)................................... 8-5130
Cutting, Range I ................035 Orifice................ 9-5702
Cutting, Range II ...............047 Orifice................ 9-5707
Cutting, Range III..............059 Orifice................ 9-5708
Gouging, All Ranges.........082 Orifice................ 8-5129
Air Operation (Cutting or Gouging) .................. 9-5619
Multi-Gas (Cutting or Gouging) ......................... 9-5711
Air electrodes are for use with air only. Do not use air
electrodes for multi-gas (nitrogen or argon/hydrogen)
operation. Multi-gas electrodes can be identified by the
ring around the diameter.
2. Connect primary power to the system (close main
disconnect switch or plug unit in).
3. Turn gas supply on.
4. Move the ON/OFF switch to ON position (if the RUN/
SET switch is in SET position, gas will flow).
5. Set the current range (see Cutting Speeds, pages 24-25).
6. Move the RUN/SET switch to SET position. Set plasma
and secondary gas pressures.
7. Purge for approximately three minutes by letting air
run. This will remove any condensation of moisture
that may have accumulated in the torch while the
system was shut down.
8. Return the RUN/SET switch to RUN position.
The system is now ready for operation.
