OPERATION 8 Manual 0-2577
Disconnect primary power at the source before disassembling
the power supply, torch, or torch leads.
Follow this set-up procedure each time the system is operated:
1. Check the torch for proper assembly and appropriate front
end torch parts (see Section 4.5, Replacing Consumable Torch
Parts).
The power supply will not operate unless the torch shield cup is
fully seated against the PIP (Parts in Place) pins in the torch
head.
2. Check the power source for proper input voltage. Make sure
the power source meets circuit protection and wiring require-
ments (see Section 2.2).
3. Check for a solid work cable connection to the workpiece.
4. Select desired gas (air or nitrogen). Make sure gas sources
meet pressure and flow requirements (see Section 2.3, Gas
Connections). Check connections and turn gas supply on.
5. Select the desired current output level (12 to 20 amps).
7. Move the RUN/SET switch to SET position. Adjust the gas
pressure to 50 psi (3.5 BAR).
8. Set the RUN/SET switch to RUN position.
The system is now ready for operation.
