Connecting And Disconnecting Torch Turn off power source and disconnect input power. 1 Torch Connector 2 Quick Connect Collar 3 Nipple 4 Receptacle 5 Securing Pin To connect torch: Push torch connector onto receptacle and quick connect until collar secures nipple. Rotate securing pin to lock connector to unit. To disconnect torch: Rotate securing pin to unlock connector from unit. Push quick connect collar back towards unit to release nipple, and pull torch connector away from unit. 804 055-A 2 1 3 4 5 . A complete Parts List is available at 4-7. Electrical Service Guide . CAUTION: INCORRECT INPUT POWER can damage this welding power source. This welding power source requires a CONTINUOUS supply of 50 or 60 Hz (10%) power at +10% of 575V or .10% of 208V input voltage. Phase to ground voltage shall not exceed +10% of rated input voltage. Do not use a generator with automatic idle device (that idles engine when no load is sensed) to supply input power to this plasma power source. 60 Hz Three Phase Input Voltage 208 230 460 575 Input Amperes At Rated Output 55 49 24 19 Max Recommended Standard Fuse Rating In Amperes 1 Time-Delay 2 Normal Operating 3 60 80 60 70 30 35 20 30 Min Input Conductor Size In AWG 4 8 8 10 12 Max Recommended Input Conductor Length In Feet (Meters) 89 (27) 108 (33) 284 (87) 268 (82) Min Grounding Conductor Size In AWG 4 8 8 10 12 Reference: 2005 National Electrical Code (NEC) (including article 630) 1 Consult factory for circuit breaker applications. 2 “Time-Delay” fuses are UL class “RK5” . 3 “Normal Operating” (general purpose - no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp and above). 4 Conductor data in this section specifies conductor size (excluding flexible cord or cable) between the panelboard and the equipment per NEC Table 310.16.
