2. To install a new 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 assem-
bly and into the gun. If the conduit should lodge along the way, gently whip or work the cable assembly to aid
forward movement.
When the conduit stop meets the end of the connector plug and the new raw end extends through the end of
the conductor tube on the welding gun, tighten the Allen screw in the connector plug onto the conduit to
prevent its backward movement.

NOTE
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 4-13. 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.
3. Replace Gas Diffuser, Contact Tip, Insulator and Nozzle.
4. Tighten the Allen screw in the conductor tube.
CAUTION
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.
4.05 MIG Gun Maintenance
Remove dust and metallic particles from the gun conduit by forcing clean, dry compressed air into the conduit once
a week. This will minimize wire feeding problems.
