K240 CONTACTOR KIT

Output contactor with pilot relay to make the electrode ‘cold’ when not welding. Must be ordered when using the LN-8 with SA-750, SAE, TM, R3M and R3R Idealarcs. Contactor kits are rated at 600 amps maxi- mum, and cannot be paralleled with each other.

K317 DUAL PROCESS KIT (NO POLARITY CHANGE)

The Dual Process Kit is a transfer device that con- nects two wire feeders to a single power source and enables each wire feeder to weld a different proce- dure without changing any of the dials. When used with the DC-600, the wire feeders can be set for differ- ent modes; CV Innershield or CV Submerged Arc. Both wire feeders will operate at the same polarity.

K318 DUAL PROCESS CONTACTOR KIT (WITH POLARITY CHANGES)

The Dual Process Contactor Kit permits the connec- tion of two wire feeders to a single power source and enables each wire feeder to weld at a different proce- dure and polarity without changing any dials or switch- es. When used with the DC-600, the wire feeders can be set for different modes; CV Innershield or CV Submerged Arc. The kit can also be connected to operate with the same polarity on each wire feeder.

K1504-1 60 lb Wire Reel

K438 60 lb Readi-Reel Adapter

K162 SPINDLE FOR MOUNTING READI-REELS AND 10 THRU 30 lb (4.5 THRU 13.5 kg) SPOOLS

For use with the K303 wire reel stand. To mount this spindle kit, remove the shaft from the standard 50 to 60 lb (22.5 to 27.2 kg) wire coils from the mounting framework. Install the spindle per the instructions shipped with the kit.

K377 SMALL MOUNTING STAND FOR READI-REEL COILS OR 10 THRU 30 lb (4.5 THRU 13.5 kg) SPOOLS WITH 2 in. (50 mm) I.D.

This assembly includes a wire reel spindle (similar to the K162 spindle) attached to a small frame. The unit is supplied with the K363 Readi-Reel Adapter for using the Lincoln “Readi-Reel Electrode Coils”. Without the adapter, the unit is capable of handling spools with a 2 in. I.D., a 12 in. maximum O.D., and a 4 in. width. The spindle has an adjustable breaking system.
