ii ii SAFETY ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands. 3.b. Insulate yourself from work and ground using dry insulation. Make certain the insulation is large enough to cover your full area of physical contact with work and ground.
iii iii SAFETY WELDING and CUTTING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas. Avoid welding near hydraulic lines. Have a fire extinguisher readily available. 6.b.

A-3 A-3 INSTALLATION GENERAL DESCRIPTION WARNING • Do not touch electrically live parts such as output terminals or internal wiring -----------------------------------------------------------------------The K126 Innershield Pro gun and cable assemblies have been designed specification for welding with mild steel FCAW-S (self-shielded flux cored) processes. The K126 Pro product is designed for extended life and improved wire feeding in heavy duty welding applications.
A-4 INSTALLATION Read this entire installation section before you start installation. A-4 Connection to Adapted Feeders, Lincoln DH-10, LN-10, STT-10, and Power Feed 10 wire feeders (5/64” or smaller diameter wire). SAFETY PRECAUTIONS WARNING The K126-12 gun and cable assembly will connect easily to any properly adapted feeder. ELECTRIC SHOCK can kill. • Do not touch electrically live parts such as output terminals or internal wiring. • Insulate yourself from the work and ground.
A-5 A-5 INSTALLATION K466-4 Installation (For Hobart feeders; i.e. 27...) 1. Remove brass cable connector (see Figure A.2) from the K466-4 kit and screw it on to the feeder end of the gun cable. Tighten the connector with the wrench provided. 2. Attach the phone plug connector of the gun control cable provided to the trigger connector on the front of the Hobart feeder. K466-6, K466-7, and K466-9 Installation (Wirematic, Hobart Series 2000 Feeders, SP100T Type and Power MIG) 1.
A-6 INSTALLATION 2. Attach the round connector of the gun control cable provided to the trigger connector on the front of the Lincoln Feeder.

D-1 D-1 MAINTENANCE REMOVAL, INSTALLATION AND TRIMMING INSTRUCTIONS FOR MAGNUM® LINERS NOTE: The maximum wire size for a K466-3 and K466-4 is 5/64”. Therefore the 3/32” and 1/8” liners are not included with these kits. NOTE: The variation in cable lengths prevents the interchangeability of liners. Once a liner has been cut for a particular gun, it should not be installed in another gun, unless it can meet the liner cut off length requirement.
