GMA TIMER KIT (K418)
Provides the following functions:
1.Preflow Control - Provides flow of shielding gas to the work before the arc is established. The sole- noid valve is energized immediately when the gun trigger is closed but the time delay before the wire feeder is energized is adjustable from 0 to 1.5 seconds.
2.Postflow Control - Provides flow of shielding gas to the work after welding is stopped. Delay of the shut off of the solenoid valve after the gun 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 wire size, processes, pro- cedure, etc.
4.Purge - Cold Inch Switch - One momentary posi- tion energizes the gas solenoid valve but not the wire feeder or power source. The other momen- tary position energizes the wire feeder but not the power source or solenoid valve. For GMA models only.
Install the kit according to the M15059 instructions included with the kit.
DUAL PROCESS KIT (K317) - For Wire Feeders
Using Same Polarity
This kit permits the connection of two wire feeders to a single power source. Both feeders must weld with the same electrode polarity. When the trigger of the desired wire feeder is pressed, the power source out- put control leads (#75, #76 and #77) will be connected to that feeder, and the procedure as set on its controls will be provided. The other connected wire feeder will not be feeding wire, but its electrode circuit will be elec- trically hot. The kit mounts at the power source and is connected to the power source terminal strip with the supplied leads. Standard K196 input cable assemblies are used to connect each wire feeder to the dual process control circuit while the electrode lead con- nects to the power source.
Install the kit according to instructions included.
DUAL PROCESS KIT (K318) - With Electrode
Polarity Change Capability
Functions essentially the same as the K317 except that the kit includes two contactors to provide different polarities on the two wire feeders. When connected in this manner and one trigger is pressed, the other elec-
trode will be "cold" to ground but "hot" to the other elec- trode. This kit can also be connected to provide the same polarities on each feeder, but the electrode circuit of the one not being used will be cold to work and to the other electrode.
Install the kit according to instructions included.
NOTE: The K317 and K318 Dual Process Kits also include mode change capability, but only when using the
When using the Pulse Power 500 power source, the K317 or K318 Dual Process Kits can be used only if the procedures are close enough to use the same mode setting. The K317 or K318 cannot switch modes on the Pulse Power 500. An
DUAL PROCEDURE KIT (K319)
With the use of this kit, one of two different settings of wire feed speed and voltage can be selected by a tog- gle switch mounted on the gun handle. The kit consists of a control panel which mounts over the standard LN- 9 GMA control rheostats. This control panel has four rheostats, a transfer relay and a polarized connector. During installation, the standard security door is mount- ed over the new panel and functions in the same man- ner. All electrical connections are with plugs to speed and simplify the assembly. A
