K126-[ ] INNERSHIELD® PRO
A-3
The K126 Innershield Pro has stainless steel jacketed
goosenecks for extended life. The goosenecks are
similar in structure to a MIG gun gooseneck. A
copper 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
continuously 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.

GENERAL DESCRIPTION
• 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.
