ESAB FABRICATOR 252i
INSTALLATION/SETUP 3-24 Manual 0-5423
3.19 Set-up for MIG (FCAW) Welding with Gasless MIG Wire
The Fabricator 252i is supplied with a ESAB Fusion 250 AMP air-cooled MIG Gun. The ESAB Fusion 250A MIG Gun is designed with an
ergonomic handle and fewer parts to cause performance problems. The Fusion MIG Gun uses standard readily available ESAB Velocity
consumable parts.
When using a gasless flux cored wire, you do not need to have an external gas source attached to the unit. For most Self Shielded Flux
Cored Wire, connect the Work Lead to the po terminal and connect the MIG Torch polarity lead to the negative - terminal. If in
doubt, consult the Flux Cored electrode wire manufacturer.

1. Turn the Main ON/OFF switch OFF (located on the rear panel).
2. Check that the MIG wire size, contact tip, MIG Gun liner and drive roll groove are all the same size before fitting the MIG wire
into the Power Source.
3. Connect the MIG Gun Polarity Lead to the negative welding terminal (-). If in doubt, consult the MIG electrode wire manufactur-
er. Welding current flows from the Power Source via heavy duty bayonet type terminals. It is essential, however, that the male
plug is inserted and turned securely to achieve a sound electrical connection.
4. Fit the MIG (FCAW) wire spool and MIG Gun to the Power Source. (Refer to section 3.08 to 3.12).
5. Connect the work lead to the positive welding terminal (+). If in doubt, consult the MIG electrode wire manufacturer. Weld-
ing current flows from the Power Source via heavy duty bayonet type terminals. It is essential, however, that the male plug is
inserted and turned securely to achieve a sound electrical connection.
6. If gasless MIG (FCAW) wire is fitted then shielding gas is not required for welding. Otherwise fit the welding grade shielding gas
regulator/flow gauge to the shielding gas cylinder (refer to Section 3.17) then connect the shielding gas hose from the rear of
the power source to the regulator/flow gauge outlet.
7. Turn the Main ON/OFF switch ON (located on the rear panel).
8. Select MIG mode with the process selection control. (Refer to Section 3.06.4 for further information)
9. Remove the MIG Gun nozzle and contact tip.
10. Depress MIG Gun trigger to feed the MIG wire out. Then fit the contact tip on the MIG wire and hand tighten the nozzle in place.
11. Refer to the Weld Guide located on the inside of the wire feed compartment door for further information on Voltage/Wirespeed
settings.
WARNING
Before connecting the work clamp to the work make sure the mains power supply is switched OFF.
