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
110 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.
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.
RESETTING THE WELDING STATION
It is possible to restore the factory settings of the welding machine. This advanced setting is accessed by pressing the «A or V display switch
button for more than 3 seconds. Then select «InI» by operating the main incremental encoder and press the AV button again to confirm this choice.
The station then displays «3», «2», «1», «rSt» and then resets the unit.
