K418 GMA TIMER KIT

This kit is available to provide the following functions:

1.Preflow Control – Provides flow of shielding gas to the work before the arc is established. The solenoid valve is energized immediately when the gun trigger is closed, but the time delay before the wire feeder is energized is adjustable to between 0 and 1.5 seconds.

2.Postflow Control – Provides flow of shielding gas to the work after welding is stopped. Solenoid valve shutoff delay after the trigger is released is adjustable from 0.5 to 4.5 seconds.

3.Burnback Control – 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 the wire size, process, procedure, etc.

4.Purge - Cold Inch Switch – Momentary Up position energizes the gas solenoid but not the wire feeder or welding power source. Momentary down position energizes the wire feeder but not the welding power source or the gas solenoid valve.

Installation and operation instructions (M15059) are included with the kit.

that freezes the display for approximately six seconds at the reading just prior to stopping welding. This feature allows the operator to easily check his procedure at the end of the weld and make adjustments if required. Installation instructions (M15080) are included with the kit.

K775 OR K857 REMOTE VOLTAGE CONTROL KIT

Either control installs on the side of the LN-7 GMA control box cover and gives voltage control at the wire feeder.

K775 can be installed on the LN-7 GMA when it is used with R3S, DC-250, DC-400, CV-400, OR DC-600 power sources. A control cable from the K775 attaches to the power source terminal strip. See the instructions (S14267) included with the kit.

K857 can be installed on the LN-7 GMA when it is used with newer Lincoln power sources such as the CV-300 with K856 remote kit installed. These power sources are equipped with a 6-socket ms-type receptacle for connection of the plug on the 28 ft (8.5 m) control cable of the K857. See the instructions (S19103) included with the kit.

A remote output is also available for use with SAM power sources. See the SAM Operating Manual.
