INNERSHIELD (FCAW)

CONVERSION

Several changes are needed to convert the unit for operation with the Innershield (FCAW) process. The K549-1 Innershield Kit includes all the necessary accessories for this conversion and are provided for this purpose. The following conversions should be made using the contents of this kit:

1.Change the output polarity to DC(-). See “Work Cable Installation” section for details.

2.Install proper drive roll for the wire size selected. See “Changing Drive Roll” in Maintenance section for details.

3.Install the proper gun liner* and tip for the wire size selected. See “Component Replacement” in Maintenance section for details.

4.Remove gas nozzle (if installed) and install gasless nozzle. To remove, simply unscrew.

* The Factory installed Gun Liner will feed (.025-.035 (0.6mm - 0.9mm) wire.
