K350 / K350-1ADAPTER KITS

The K350 Adapter kits are used to interface one or two LN-23P feeders to a Lincoln CV power source. Figure E.4 shows a typical two feeder connection using a K350-1. If only one feeder is used it must be connected to the “Feeder A” terminal strip.

NOTE: Many of the newer power sources allow a single feeder to be connected without using an adapter kit. See the connection diagrams in Section G.

WARNING

In a two feeder system, both guns will be ʻHOTʼ when either gun is triggered

In a two feeder system, triggering the second gun while one is welding may cause the feeder in use to shut down.
