WARNING: TURN THE WELDER POWER SWITCH OFF BEFORE INSTALLING GUN AND CABLE.

____________________________________

1.Lay the cable out straight.

2.Make sure all pins on the gun cable connector are aligned with the proper mating sockets on the front panel gun connector and then join the connectors and tighten the hand nut on the gun cable connec- tor.

NOTE: If a gun and cable other than the Magnum 250 SP is to be used, it must conform to standard European style connector (Magnum Fast Mate) speci- fications. See Figure A.9.

NOTE: The thumb switch functions available on the Magnum 250 SP gun will only be operable from the front panel keypad. The gun trigger switch must be capable of switching 5 milliamps at 15 volts DC resis- tive.

The gun trigger switch connected to the gun trig- ger control cable must be a normally open momen- tary switch. The terminals of the switch must be insulated from the welding circuit. Improper opera- tion of or damage to the SP-250 might result if this switch is common to an electrical circuit other than the SP-250 trigger circuit.
