• Switching on is done by turning the on/off switch (I-10) to position I, conversely switching off is done by turning to position O. Caution! Never switch

off the power supply when the welding current source is under load.

• Fan behaviour: In MMA mode, the fan runs continuously. In TIG mode, the fan runs only during the welding phase and then stops after cooling.

CONNECTION TO A GENERATOR

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

- The voltage must be alternating, with an effective value of 400 V +/- 15%, and a peak voltage of less than 700 V,

- The frequency must be between 50 and 60 Hz.

It is imperative to check these conditions, as many generators produce high voltage spikes that can damage the equipment.

USE OF EXTENSION CORDS

All extension cords must be of a size and cross-section appropriate for the voltage of the equipment. Use an extension cord that complies with national

regulations. Power, extension and welding cables should be fully unwound to avoid overheating.

PRIMING OF THE COOLING UNIT

When using the product for the first time or after the coolant tank has been completely emptied, the following procedure must be followed to prime

the circulator with liquid:

- Fill the reservoir to its maximum level with coolant.

- Connect the coolant priming kit (I-14) to the unit's coolant connector (blue fitting). Place the other end of the kit in an empty container.

- Turn on the liquid circulator. To activate it, depending on the product, you will need to connect a torch and then pull the welding trigger, or simply

power up the unit.

- The circulator should start instantly and the liquid should flow into the container. If the circulator still does not prime, turn off the power supply,

inject compressed air into the Priming Kit to flush the liquid from the pipes and then restart the circulator.

- Once the pump has been primed (container filling with coolant), stop the chiller by pressing one of the buttons on the HMI.

- As soon as the liquid flows, the circulator is primed. Turn off the unit, disconnect the Priming Kit, top up the coolant in the reservoir and connect

your system to the unit's fluid connections. Your cooling unit is primed and ready for operation.

LIQUID COOLING

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

level unless a warning message is displayed.

It is essential to use a specific coolant for welding machines with low electrical conductivity, being anti-corrosion and anti-freeze.

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 clogging the circuit.

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

Any damage to the machine caused by the use of a coolant other than the recommended type will not be considered under the warranty.

Ensure that the cooling unit (or generator with cooling unit) is disconnected from the power supply before connecting or disconnecting the torch liquid

cooling hoses (inlet and outlet).
