GYS KRYPTON 321 DC TRI Manual De Uso página 30

User manual
The actual absorbed current (I1eff) for optimal operating conditions is indicated on the equipment. Check that the power supply and its protection
(fuse and/or circuit breaker) are compatible with the current required to run the machine. In some countries, changing the plug may be necessary to
ensure the machine's optimum performance.
This machine will enter a protection mode if the supply voltage is higher or lower than 15% of the specified voltage(s) (a fault code will appear on the
keypad display).
KRYPTON 231 DC FV :
Starting is done by pressing the START/STOP switch (On), and stopping is done by pressing the same switch (Off)
KRYPTON 321 DC TRI :
Starting is done via an on / off switch set to I, and the stop is done by switching it to O.
Warning! Never switch off the power supply while the unit is under load.
• Fan performance: this product is equipped with an intelligent ventilation management system to minimise the noise of the machine. The fans will
adjust their speed according to useage and the surrounding temperature. In MMA mode, the fan will run continuously. In TIG mode, the fan runs only
during the welding phase and stops after cooling.
• Caution: Increasing the length of the torch or earth return cables beyond the maximum length specified by the manufacturer increases the risk of
electric shock.
• The arc ignition and stabilisation device is designed for manual and mechanically guided operation.
CONNECTING TO A POWER SOURCE
This equipment can be powered by a generator, provided that the auxiliary power supply meets the following requirements:
- The voltage must be alternating, set as specified, and with a peak voltage of less than 700 V for the KRYPTON 321 DC and 400 V for the KRYPTON
231 DC FV.
- 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 an appropriate length and cross-section to suit the voltage of the equipment. Use an extension lead that complies with
national safety regulations.

GAS SUPPLY
This machine is equipped with two connectors. A connector for the gas cylinder inlet to the machine, and a connector for the gas outlet
at the end of the torch. We recommend that you use the adapters supplied with your machine to ensure the best possible fit.
ACTIVATION OF THE VRD FUNCTION (VOLTAGE REDUCTION DEVICE)
The voltage reduction device (or VRD) is used to protect the welder. The welding current is only delivered when the electrode is in contact with the
workpiece (low resistance). As soon as the electrode is removed, the VRD function lowers the voltage considerably.
By default, the voltage reduction device is deactivated. In order to activate it, the user must open the product and complete the following procedure:
1. DISCONNECT THE PRODUCT FROM THE POWER SUPPLY AND WAIT 5 MINUTES FOR SAFETY.
2. Remove the side of the power source (see page at the end of the manual).
3. Locate the control board and the VRD switch (see page at the end of the manual).
4. Toggle the switch to the ON position.
5. The VRD function is activated.
6. Reinstall the side panel of the unit.
7. The VRD icon on the interface (HMI) will be lit.
To deactivate the VRD function, simply flip the switch back to the opposite position.
