9.4 Installing A New Wire Conduit
a) Be sure the MIG Torch cable is arranged in a straight line, free from twists, when
installing or removing a wire conduit. Remove the old conduit by first removing the MIG
Torches nozzle, contact tip and gas diffuser. Then loosen Allen screws in the conductor
tube and connector plug and pull the old wire conduit out of the cable assembly from the
connector plug end.
b) To install a new wire conduit, first inspect the o-ring gas seal on the conduit for cuts or
damage. Start from the connector plug end of the assembly and begin pushing the conduit
through the connector plug, cable assembly and into the gun. If the conduit should lodge
along the way, gently whip or work the cable assembly to aid forward movement.
c) When the wire conduit stop meets the end of the connector plug and the new raw end
extends through the end of the conductor tube, the Allen screw in the connector plug must
be securely tightened onto the conduit to prevent its backward movement.
NOTE 5
When the conduit is fully inserted into the cable assembly and the conduit stop is firmly against the
Connector Plug, the "raw end" of the conduit will protrude out of the open end of the gun conductor tube.
Trim the conduit as shown in Figure 7. The trimmed end which seats in the Gas Diffuser must be filed and
reamed smooth on the inside and outside radii so wire feed will not be obstructed.
d) Replace Gas Diffuser, Contact Tip, and Nozzle.
e) Tighten the Allen screw in the conductor tube.
CAUTION 5
Do not over tighten the conductor tube screw as this action will result in the distortion of the conduit and
will lead to wire feedability problems.
