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.

The K126 Innershield Pro products use a cable with a core made from flat wound spring steel. The copper conductors which transmit welding current are wrapped around the spring core. Four #20 insulated leads are wrapped along with the copper conductors for use in the gun trigger circuit. The cable jacketing is made from a cross linked polymer which provides exceptional heat resistance and fatigue life.

A round wound spring steel liner is then placed inside the spring core of the cable to contain the wire while it is being transported to the welding arc. This liner is replaceable so that it can be sized correctly for the welding wire being used, and it can be removed and replaced with a new liner as it wears out. Both of these features improve the feeding of the wire through the gun.

The K126 Innershield Pro has stainless steel jacketed goosenecks for extended life. The goosenecks are similar in structure to a MIG gun gooseneck. A cop- per tube is used for the conductor and a stainless steel tube is used for the outer jacketing, while a Teflon tube acts as an insulator between the copper and steel. The replaceable spring liner extends through the gooseneck, so that the wire is continuous- ly supported throughout the gun.

The K126 Innershield Pro gun utilizes a replaceable connector assembly at the feeder end of the gun so that the gun can be easily used with any feeder. These connectors are the same K466/K613 kits used with the Magnum MIG gun product line.

RECOMMENDED PROCESSES AND EQUIPMENT

RECOMMENDED PROCESSES

PROCESS LIMITATIONS

This gun can only be used with self-shielded wires. The design will not support the use of shielding gas.

EQUIPMENT LIMITATIONS

The K126 Pro will not operate with the LN23P feed- er.

The K126 Pro does not support the 83% reduced feed speed switch for pipe welding.
