HOT START ADJUSTMENT
1) Switch on the welding machine.
2) Press quickly two times the button
SET VRD
to
enter in the Hot Start regulation.
3) The yellow over temperature led is on and the

- V.R.D.
(AVAILABLE ONLY IN
MMA
MODE)
V.R.D. MANAGEMENT
The initials V.R.D. means VOLTAGE REDUCTION
DEVICE, which is a system for reducing the no-
load voltage (OCV). When the V.R.D. is installed in
a welding machine it reduces the maximum no-
load voltage to a safety voltage which is normally
less than 25 V.
- The V.R.D. is used as an additional aid for
operator safety.
- The procedures for safety at work must always be
carried out with attention.
ACTIVATE V.R.D.
1) Switch on the welding machine.
2) Hold down button
SET VRD
on the front panel
of the machine for about 2 seconds, then release
the button; the welding enable led
4
blinks (V.R.D.
FUNCTION ON) ( Vout < 25V). VRD mode
remains activated when switching the machine off
and on again.
DEACTIVATE V.R.D.
1) Switch on the welding machine.
2) Hold down button
SET VRD
on the front panel
of the machine for about 3 seconds, then release
the button; the welding enable led
4
remains lit
with a fixed light (V.R.D. FUNCTION deactivated).
VRD mode remains deactivated when switching
the machine off and on again.
DRIVE ARC
( FUNZIONE TIG LIFT )
The base current is 10% of welding current.
