APPENDIX 2: SEQUENCE OF OPERATION (BLOCK DIAGRAM) ACTION Close external disconnect switch. RESULT Power to system. ACTION Protect eyes and activate torch RESULT Gas flows (2 seconds). After gas pre-flow: DC indicator on. Pilot arc established ACTION Torch deactivated (by torch switch release or by remote device). RESULT Main arc stops. (Power supply enable signal removed.) Gas flows (15 seconds) NOTE - If torch is activated during post-flow, pilot arc will immediately restart. If torch is within transfer distance (3/8 in) of workpiece, main arc will transfer. After post-flow: Gas solenoid closes, gas flow stops. GAS indicator off. A-03050 ACTION ON/OFF switch to ON. RESULT AC indicator blinks for 8 seconds then steady on. Fans on. Power circuit ready. PILOT ARC ACTION RUN/SET switch to SET. RESULT Gas solenoid open, gas flows to set pressure. GAS indicator on. ACTION ON/OFF switch to OFF RESULT All indicators off. Power supply fans off. ACTION STANDARD/LATCH switch to STANDARD ACTION STANDARD/LATCH switch to LATCH ACTION Torch moved away from work (while still activated). RESULT Main arc stops. Pilot arc automatically restarts. ACTION RUN/SET switch to RUN. RESULT Gas flow stops. GAS indicator off. ACTION Torch moved within transfer distance of workpiece. RESULT Main arc transfer. Pilot arc off. ACTION Torch Switch released. RESULT Transfer will continue until torch is removed from workpiece. ACTION Open external disconnect. RESULT No power to system. APPENDIX A-2 Manual 0-2697
