2 GENERAL DESCRIPTIONS

The machine is a multi-process system suitable for
pulsed synergic MIG/MAG welding, non-pulsed synergic
MIG/MAG, conventional MIG/MAG, TIG (DC) with scratch
starting of the arc and MMA, developed using inverter
technology. The welding machine is supplied complete
with WF4/P four roll wire feeder, and cooling unit.
The equipment may be used only for the purposes
described in the manual.
The equipment must not be used to defrost pipes.

This value usually corresponds to the capa-
city of the fuse (delayed type) to be used as
a protection for the equipment.
IP23 S. Protection rating for the housing.
Grade 3 as the second digit means that this
equipment may be stored, but it is not
suitable for use outdoors in the rain, unless
it is protected.

Suitable for use in high-risk environments.
NOTE:
1- The machine has also been designed for use in envi-
ronments with a pollution rating of 1. (See IEC 60664).
2- This equipment complies with IEC 61000-3-12 provided
that the maximum permissible system impedance Zmax
is less than or equal to 0,149 (Art. 387)-0,075 (Art. 389)
at the interface point between the user's supply and the
public system. It is the responsibility of the installer or
user of the equipment to ensure, by consultation with the
distribution network operator if necessary, that the equip-
ment is connected only to a supply with maximum per-
missible system impedance Zmax less than or equal to
0,149 (Art. 387)-0,075 (Art. 389).
