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.

to the gas hose nipple and secure it with the hose
clamp.
