Power Switch; Connecting To A Power Source - GYS KRONOS 400T G Manual De Uso

User manual

POWER SWITCH

This machine is fitted with a 32A socket type EN 60309-1 which must only be used on a three-phase 400 V (50-60 Hz) four-wire earthed electrical
installation.
The absorbed effective current (I1eff) is indicated on the device for optimum operating conditions. Check that the power supply and its safeguards
(fuse and/or circuit breaker) are compatible with the electric current being used. In some countries, it may be necessary to change the plug to allow
the use at maximum settings.
• The power source is designed to operate on 400V +/-15%. The unit enters protection mode if the supply voltage
is less than 330Vrms or greater than 490Vrms (a fault code will appear on the display).
• Starting is done by pressing the START/STOP switch (On), and stopping is done by pressing the same switch (Off).. Warning! Never switch off the
power supply while the unit is under load.

CONNECTING TO A POWER SOURCE

This equipment can be operated with electric generators provided that the auxiliary power supply meets the following requirements:
- The voltage must be alternating with an RMS value of 400V +/- 15% and a peak voltage of less than 700V.
- The frequency must be between 50 and 60 Hz.
It is vital to check these conditions as many generators produce high voltage peaks that can damage equipment.
USING EXTENSION LEADS
All extension leads must be of a suitable length and width that is appropriate to the equipment's voltage. Use an extension lead that complies with
national safety regulations.

COOLANT PUMP PRIMING (400T-GW)
When using the product for the first time, or after completely emptying the coolant tank, the following procedure must be followed to start the circula-
tion:
- Fill the coolant reservoir to its maximum level. The tank has a 5.5 litre capacity.
- Connect the priming hose (II-17) to the coolant outlet connector (I-13) and place the other end in an empty container (ideally a bottle).
- Turn on the power source.
- In the «System/Cooler» menu of the wire feed unit, press push button no. 2 () to start the priming procedure.
- Once the pump is primed (the tank having been filled with coolant), stop the cooling system by pressing one of the buttons on the HMI.
- Disconnect the priming hose and return the liquid to the cooling system: the pump is now primed.
LIQUID COOLING (400T-GW)
FILLING
MAX
The cooling unit tank must be filled to the MAX level indicated by the gauge on the front, and must never be allowed to fall below the
MIN level. A warning message will be triggered if this occurs.
It is essential to use a specific coolant for welding machines that has low electrical conductivity as well as being anti-corrosion and
anti-freeze (ref. 052246).
The use of other coolants, in particular the standard automotive coolants, can lead to the accumulation of solid deposits in the cooling
system through electrolysis, thus degrading the cooling system and even clogging it entirely.
This recommended MAX level is essential for optimum performance of the liquid-cooled torch.
MIN Any damage to the machine caused by the use of a coolant other than the recommended variety will not be covered under the warranty..
USAGE
NEVER USE the machine's power source WITHOUT COOLING LIQUID while the pump is running.
1.
Meet the minimum coolant level. Failure to do so may result in permanent damage to the cooling system pump.
Ensure that the cooling unit is switched off before disconnecting the torch's fluid inlet and/or outlet pipes. Coolant is harmful and irritates the
2.
eyes, mucous membranes and skin. Hot liquid can cause burns.
Danger of burns from hot liquid. Never drain the cooling unit after use. The liquid inside the machine is boiling hot, wait for it to cool before
3.
draining.
In «AUTO» mode, the cooler pump starts running when welding is started. When welding stops, the pump continues to run for a further 10
4. minutes. During this time, the liquid cools the welding torch bringing it back to room temperature. Leave the power source plugged in for a
few minutes after welding to allow it to cool.
In the MIG-MAG process, the cooling system is activated by default (AUTO). To use an air-cooled MIG-MAG torch, it is necessary to switch the cooling
system off. To do this, please refer to the wire feeder interface manual.
