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 manufacturer. 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 manu-
facturer. 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.
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.
CAUTION
Loose welding terminal connections can cause overheating and result in the male plug being fused in the
terminal.
Remove any packaging material prior to use. DO NOT block the air vents at the front or rear of the Welding
Power Source.
NOTE
Depending on the type of wire you will be using the MIG Gun polarity may need to be switched. Follow the
wire manufacturers recommendation.
3.20 Set-up for LIFT TIG (GTAW) Welding
!
WARNING
Before any welding is to begin, be sure to wear all appropriate and recommended safety equipment.
NOTE
The following steps will assume that you have already set up the proper shielding gas as outlined in Sub
Section 3.17.
