INSTALLATION
3.07 Attaching the Gun and Cable
Assembly to the Power Source
The Fabricator 140/180 is supplied with a 180A MIG gun.
The 180A MIG gun is designed with an ergonomic handle
and fewer parts to eliminate performance problems. The
180A MIG gun uses standard readily available TWECO
consumable parts.
1. Open the door to the machine.
2. Connect the gun cable to the power source by first
routing the switch lead through the access hole in
the front panel followed by the gun cable (see
Figure 3-3).
NOTE:
Turn the cable end to align the gas hose nipple
on the connector plug with the keyway located
in the bottom of the front panel access hole.

3. Loosen the thumbscrew and insert the gun cable end as
far as it will go. Tighten thumbscrew (see Figure 3-3).
4. Insert the gun switch plug into the gun switch socket
(see Figure 3-3).
5. If shielding gas is being used, push the gas hose on
to the gas hose nipple and secure it with the hose
clamp.
6. To remove the gun, simply reverse these directions.
When disconnecting gun switch leads from
the machine, grab the connectors and pull. Do
not pull on the wires.
