The LN-7 GMA has the factory installed gas solenoid valve leads attached to terminals 7 and 32A. Additional auxiliary equipment connection is not recommended. If the gas solenoid is NOT connected to terminals 7 and 32A, other auxiliary equipment may be connected but the current draw must NOT exceed 1/4 ampere.

CAUTION

Do not connect the power source contactor to these terminals.

NOTE: The auxiliary equipment contacts open when the trigger is released. When the optional K418 GMA Timer Kit is installed, the auxiliary contacts open after the postflow time delay.

Do not use coils or spools heavier than 30 lbs on the original K162 spindle.

To mount the 2 in. spindle kit for Readi-Reels and 10 through 60 lb spools, remove the shaft for the standard 50-60 pound wire coils from the mounting framework. Install the spindle per the instructions (M15241) shipped with the spindle kit.

K163 UNDERCARRIAGE

The undercarriage includes casters, wheels, a handle, and related hardware. Casters are mounted at the front and wheels at the rear of the platform. The handle is bolted to the front of the platform so the wire feeder can be tilted back and wheeled like a two-wheel truck. Installation sheet M13424 is provided with the undercarriage.

K178-1 MOUNTING

PLATFORM

This is a turntable type platform for mounting the LN-7 GMA to the top of Idealarc power sources. Bolt the platform to the lift bail per the instructions (M16260) supplied with the platform.

K162H SPINDLE

The K162H spindle is used for mounting Readi-Reels and 2 in. I.D. spools with a 60 lb capacity on a K303 or K376 Wire Reel Stand. When used with Read-Reels, a Read- Reel Adapter is required. For 8 in. O.D. spools, a K468 Spindle Adapter is available.

The K162H is a high capacity design which replaces the original K162 30 lb spindle. The K162H spindle has a white spacer and has part no. M-14587-1 molded on. The original K162 spindle has a black spacer and the part no. M14587. Parts may not be exchanged from one design to the other.

K419 BURNBACK TIMER KIT

The kit is available for those applications where the LN-7 GMA is used for higher speed, fine wire feeding (0.023 in. to 0.045 in. wire sizes) where there is a tendency for the electrode to overrun at the end of the weld causing “sticking” in the crater. The kit provides a precise time delay that allows the wire to be burned off at the end of the weld. The delay is adjustable for optimum burnback depending on wire size, process, procedure, etc. This kit also includes a cold inch switch.

The K419 Burnback Kit is also useful for those installations where the gun is clamped in a fixture and cannot be lifted from the work at the end of the weld.

Installation and operation instructions (M15060) are included with the kit.
