ESAB FABRICATOR 141i
7. Negative Welding Output Terminal
The negative welding terminal is used to connect the welding output of the Power Source to the appropriate welding accessory
such as the MIG Gun (via the MIG Gun polarity lead), TIG Torch or work lead. Negative welding current flows to the Power Source
via 25mm Dinse style connector. It is essential, however, that the Dinse adapter and male plug are inserted and turned securely
to achieve a sound electrical connection.
CAUTION
!
Loose welding terminal connections can cause overheating and result in the male plug be-
ing fused in the Dinse connector..
8. Remote Control and Spool Gun Socket
The 8 pin socket is used to connect the Fusion MIG Gun, remote control device or spool gun plug to the welding Power Source.
To make connections, align keyway, insert plug, and rotate threaded collar fully clockwise.

8
Wiper arm connection to 5k ohm remote control Volts MIG mode potentiometer.
Note that the Local/ Remote Switch (Control No. 18) located in the wirefeed compartment should be set to Remote for remote
amperage/voltage controls to operate.
9. Multifunction Control - Voltage, Down Slope & Arc Force
The multifunction control knob is used to adjust Voltage (MIG Mode), Down slope (LIFT TIG Mode) and Arc Force (STICK Mode)
depending on the welding mode selected.
NOTE!
The preview functionality provided on this power source is intended to act as a guide only. Some dif-
ferences may be observed between preview values and actual welding values due to factors including
the mode of welding, differences in consumables/gas mixtures, individual welding techniques and the
transfer mode of the welding arc (ie dip versus spray transfer). Where exact settings are required (in the
case of procedural work), it is recommended that alternate measurement methods be utilized to ensure
output values are accurate.
