CONNECTION TO A GENERATOR

This equipment may operate with generators provided that the auxiliary power meets the following requirements:

- The voltage must be alternating, adjusted as specified and with a peak voltage of less than 400 V,

- The frequency must be between 50 and 60 Hz.

It is imperative to check these requirements as many generators generate high voltage peaks that can damage the machine.

USE OF EXTENSION LEADS

All extension cables must have an adequate size and section, relative to the machine's voltage. Use an extension lead that complies with national

safety regulations.

Voltage input

230 V

GAS CONNECTION

This equipment is equipped with two connections. A cylinder connector for the gas inlet into the station, and a torch gas connector for the gas outlet at

the end of the torch. We recommend that you use the adaptors supplied with your set to ensure an optimal connection.

LIQUID COOLING

FILLING THE DEVICE

The tank of the cooling unit must be filled to the recommended MAX level of the gauge on the back of the cooling unit, but never

below the MIN level, unless a warning message is displayed.

MAX

Use a coolant with low electrical conductivity, anti-corrosion and anti-freeze specific to welding machines (recommended coolant ref

052246).

To obtain the best cooling performance from this unit, distilled or demineralised water should be used. Please note that water can

only be used in ambient temperatures above 5°C.

The use of other coolants, and in particular standard automotive coolant, can lead to the accumulation of solid deposits in the cooling

circuit through electrolysis, thus degrading the cooling, and even blocking the circuit.

This recommended MAX level is essential to optimise the operating factors of the associated water-cooled torch.

MIN

Any damage to the machine caused by the use of a coolant other than the recommended type or distilled or demineralised water will

not be considered under the warranty.

HOW TO USE

NEVER USE the cooling unit WITHOUT COOLANT when the pump is running.

1.)

Respect the minimum coolant level. Failure to do so may result in permanent damage to the cooling system's pump.

Ensure that the cooling unit is switched off before disconnecting the liquid-cooled torch's inlet and/or outlet pipes. Coolant is hazardous and

2.)

irritates eyes, mucous membranes and skin. The hot liquid can cause burns.

3.)

Hot liquid burn hazard. Never drain the cooling unit after use. The liquid inside will be boiling, wait for it to cool down before draining.

The cooling unit must be switched off (OFF) to use an air-cooled TIG torch. For further instructions on how to do this, see page 33.

ACTIVATION OF THE VRD FUNCTION (VOLTAGE REDUCTION DEVICE)

This device protects the welder. The welding current is delivered only when the electrode is in contact with the part (low resistance). As soon as the

electrode is removed, the VRD function lowers the voltage to a very low value.

The VRD function is disabled as standard. However, this can be activated by means of an ON/OFF switch on the power source control board. To

access it, follow the steps below:

1. DISCONNECT THE PRODUCT FROM THE POWER SUPPLY BEFORE HANDLING.

2. Remove the screws to take the power source cover off.

3. Locate the switch on the main board (circled in the diagram below).

4. Turn the switch located on this control card ON.

5. The VRD function is activated.

6. Screw the power source cover back on.

7. On the interface (HMI), the VRD function LED is lit.

To deactivate the VRD function, simply turn the switch located on the control board back to OFF.

The VRD LED on the HMI is turned off.
