OPTIONAL ACCESSORIES

1.K549-1 .035" (0.9 mm) Innershield® Welding Kit

— Includes a contact tip, a gasless nozzle and a

.035/.045" (.9/1.2 mm) cable liner to permit the Magnum™ 100L gun and cable to use .035" (0.9 mm) diameter flux-cored electrode. The fitting on the end of the liner is stenciled with the maximum rated wire size (.045"/1.2 mm). Also included is a 10 lb. (4.5 kg.) spool of .035" (0.9 mm) Innershield NR-211-MP.

See “Innershield (FCAW) Conversion” in this sec- tion for installation instructions and MAINTE- NANCE section for proper feeding component con- figuration and installation.

2.K664-2 Aluminum Feeding Kit — This kit required for welding with .035 Aluminum wire. This kit may also be used for feeding .035 stainless wire. Included with this kit are a drive roll, liner and contact tip. It is important when changing between welding with steel wire and aluminum to exchange these components due to the lubricant applied to steel wire. Failure to do so may result in contaminated welds when weld- ing aluminum.

3.KP665-045C Drive Roll – Optional — Knurled drive roll for feeding .035 (0.9 mm) diameter flux- cored electrode.

4.K695-1 Spot / Stitch Timer Kit — Includes spot timer to control the spot welding arc time, and a stitch timer to control the on/off cycle time of the arc to prevent burnthrough on thin gauge metals. Also includes spot welding nozzle.

The Spot/Stitch Timer Kit installs inside the wire feed compartment, replacing the blank panel locat- ed below the gun trigger lead connectors, per the installation instructions (M17920) included with the kit.

5.K520 Utility Cart — Designed to transport the Lincoln family of small welders. Has provisions for mounting a single gas cylinder. Has front casters and large rear wheels.
