Operation
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 tting the MIG wire into the Power Source.
3. Connect the MIG Gun Polarity Lead to mig torch connector. If in doubt, consult the MIG
electrode wire manufacturer. Welding current ows 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 machine.
5. Connect the work lead to the positive welding terminal (+). If in doubt, consult the MIG
electrode wire manu- facturer. Welding current ows 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 / ow gauge to the shielding gas
regulator/ow gauge outlet.
7. Turn the Main ON/OFF switch ON (located on the rear panel).
8. Select MIG mode with the process selection control.
9. Remove the MIG Gun nozzle and contact tip.
10. Depress MIG Gun trigger to feed the MIG wire out through the MIG Gun gas diffuser then
fit the contact tip on the MIG wire and securely fasten it to the MIG Gun then fit 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 isswitched 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.
Depending on the type of wire you will be using the MIG Gun polarity may need to be switched.
Follow the wire manufacturers recommendation.

2.13 Set-up For LIFT TIG (GTAW) Welding (only for R231)
WARNING
Before any welding is to begin, be sure to wear all appropriate and recommended safety equipment
The following steps will assume that you have already set up the proper shielding gas.
The following set up is known as Straight Polarity or DC Electrode Positive. This is commonly
used for DC LIFT TIG welding on most materials such as steel and stainless steel.
7. Install the tungsten with approximately 1.0mm to 3.2mm sticking out from the gas cup,
ensuring you have correct sized collet.
8. Tighten the back cap.
9. Turn the switch to the “ON” position. The power L.E.D. light should illuminate.
10. Set the welding process to LIFT TIG.
11. Set the Weld Current Control Knob to the desired amperage.
12. You are now ready to begin LIFT TIG Welding.

1.Switch the ON/OFF Switch (located on the rear panel) to OFF.
2.Connect the work earth clamp to the positive output terminal, and the LIFT TIG Torch
cable to the negative output terminal. Refer to Figure 5-02.
3.Connect the gas line/hose to the proper shielding gas source. and connect the aviation
plug for trigger switch to 5 pin control socket Refer to Figure 5-02.
4.Slowly open the Argon Cylinder Valve to the fully open position.
5.Connect the work earth clamp to your work piece.
6.The tungsten must be ground to a blunt point (similar to a pencil) in order to achieve
optimum welding results. (Refer to Figure: 5-01). It is critical to grind the tungsten
electrode in the direction the grinding wheel is turning. Grind at a 30 degree angle and
never to a sharp point.
