Lifting with hoist and strap
Lift the machine by using ONLY both handles as
shown on the picture.
Keep the machine as horizontal as possible
INSTRUCTION FOR
INSECURE POSITIONING
Failure to properly secure the machine can cause
personal injury. If machine is in an insecure
position do not attempt to switch on. Do not put the
machine on an unlevelled surface greater than 10°.

PREPARING FOR
ELECTRODE WELDING
1) Respect the indications given previously
concerning primary connection and installation.
2) Connect the earth cable to the socket of the
machine. Negative polarity ( - )
3) Connect the electrode holder to the socket of
the machine. Positive polarity ( + );
4) Insert the bare core of the electrode in the gun;
5) Press the Mode (ref.6) button to select the
ELECTRODE mode, indicated by the LED
(ref.1,2,3);
6) Set the welding current with the encoder
A/SET(ref.11).
7) Proceed with welding.
V.R.D. (ONLY IN MMA/TIG/GOUGING MODE)
The initials V.R.D.
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 18V.
- 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.
ACTIVATION OF V.R.D.
1) Switch on the welding machine;
2) Hold down button Mode (ref.6)
seconds, then release the button; the led indicating
mode start blinking

switching the machine off and on again.
DEACTIVATION OF V.R.D.
1) Switch on the welding machine.;
2) Hold down button Mode (ref.6)
seconds, then release the button; the led indicating
electrode mode remains lit with a fixed light (V.R.D.
FUNCTION deactivated). VRD mode remains
deactivated when switching the machine off and on
again.
PREPARING FOR TIG
WELDING
1) Respect the indications given previously
concerning primary connection and installation.
2) Connect the earth cable to the socket of the
machine. Positive polarity ( + )
3) Connect the torch coupling to the socket of the
machine. Negative polarity ( - )
4) Connect the gas coupling of the torch to the gas
connector in the front of the generator.
5) Connect the gas bottle to the connector
provided on the rear of the generator.
6) With the Mode button (ref.6) to select the TIG
LIFT mode (ref.4)
7) Set the welding current with the encoder
A/SET (ref.11).
8)Proceed with welding.
