Operation

DTX-2200-3000 AC/DC
When the control panel switches on the VRD LED will come on and will be GREEN, which means that the VRD
function is on.
To “deactivate” the VRD device and therefore start to weld, follow this simple procedure: First touch the work piece
with the electrode, then detach it and ignite the arc within a MAX of 0,3 seconds, otherwise if this time is exceeded
the VRD device starts and prevents welding.
During welding the VRD LED turns RED, which does not indicate any malfunction on the welding machine, but
that the VRD device has been deactivated to allow welding.
14.3.16 Auxiliary functions
“Energy saving”
This function manages correct functioning of the cooling fan and cooling equipment that only run when strictly
necessary, that is:
• FAN MOTOR - The fan is activated when:
- During welding or for a certain period of time after this is finished.
- When the thermostat intervenes or for a certain period of time after it has just been reset.
• COOLING DEVICE - The cooling device is activated:
- When the machine is switched on for about 1 minute in order to allow the cooling liquid to circulate through
the equipment at the correct pressure (if the error message does not disappear from the DISPLAY (D)
when the cooling equipment switches off, contact our technical assistance department).
- During welding or for a certain period of time after this is finished.
14.3.17 Factory default
WARNING: This operation results in complete resetting of all parameters to the factory settings.
To reset the settings, you must:
• With the machine switched on, push and hold down the WELDING MODE (T7) and SELECT WELDING
PROCESS (T9) buttons simultaneously for about 3 seconds.
• Switch on the welding machine and hold down the keys until the DISPLAY (D) reads 80.
• Release the two keys.
• The reset procedure has now been completed successfully.
