17. Intelligent Fan Control The Fabricator 141i is designed with an intelligent fan control. It automatically switches the cooling fan off when it is not required. This has two main advantages; (1) to minimize power consumption, and (2) to minimize the amount of contaminants such as dust that are drawn into the Power Source.
ESAB FABRICATOR 141i 4.02 Attaching the Fusion 140A MIG Gun Fit the MIG Gun to the Power Source by pushing the MIG Gun connector into the MIG Gun Adapter and tightening the Locking Screw to secure the MIG Gun in the MIG Gun Adapter.
ESAB FABRICATOR 141i 4.03 Inserting Wire into the Wire Feed Mechanism Release the tension from the Pressure Roller Arm by turning the adjustable Wire Drive Tension Screw in a counterclockwise. Then to release the pressure roller arm push the tension screw toward the front of the machine which releases the pressure roller arm.
ESAB FABRICATOR 141i 4.04 Installing 4" (100mm) Diameter Spool As delivered from the factory, the Power Source is fitted with a Wire Spool Hub which accepts a 8" (200mm) diameter spools. In order to fit a 4" (100mm) diameter spool assemble parts in the sequence shown below in Figure 4-8.
ESAB FABRICATOR 141i 4.07 Changing the Feed Roll To change feed roll remove the feed roll retaining screw by turning in an counterclockwise direction. Once the feed roll is removed then to replace feed roll simply reverse these directions. A dual groove feed roller is supplied as standard. It can accommodate 023"(0.6mm) -.030" (0.8mm) diameter hard wires. Select the roller required with the chosen wire size marking facing outward.
ESAB FABRICATOR 141i Wire Reel Brake Adjustment Nut Art # A-10361 Figure 4-12: Wire Reel Brake 4.09 Flowmeter/ Regulator Operation With the flowmeter/ regulator connected to cylinder or pipeline, and the adjustment screw/knob fully disengaged, pressurize as follows: 1. Stand to one side of flowmeter/ regulator and slowly open the cylinder valve. If opened quickly, a sudden pressure surge may damage internal parts.
ESAB FABRICATOR 141i 4.10 Setup for MIG (GMAW) Welding with Gas Shielded MIG Wire A. Select MIG mode with the process selection control. (Refer to Section 4.01 for further information) B. Connect the MIG Gun Polarity Lead to the positive welding terminal (+). If in doubt, consult the electrode wire manufacturer.
ESAB FABRICATOR 141i 4.11 Setup for MIG (FCAW) Welding with Flux Core (Gasless) Wire A. Select MIG mode with the process selection control (refer to Section 4.01.12 for further information). B. Connect the MIG Gun Polarity Lead to the negative welding terminal (-). If in doubt, consult the electrode wire manufacturer.
NOTE! A ESAB 17V TIG torch with an 8 pin plug must be used to turn the weld current on/off via the TIG torch trigger switch to TIG weld OR a ESAB Foot Control with an 8 pin plug must be used to turn the weld current on/off as well as providing remote control of the weld current.
