- Fix the two welding cables as close to each other as possible.
- Operators must keep their heads and trunks as far away as
possible from the welding circuit.
- Operators must neverwind the weldingcables around their
body.
- Operators must never keep their body in the centre of the
welding circuit while they weld. Operators must keep both
cables on the same side of their body.
- Connect the welding current return cable to the piece to be
welded, as close as possible to the join being made/welding
spot.
- Never weld while remaining close to, sitting on or leaning

ADDITIONAL PRECAUTIONS
- WELDINGOPERATIONS:
- Inenvironmentswithincreasedriskofelectricshock;

of other people trained in emergency procedures.
The technical protection means described in sections 7.10;

up between two different electrode holders or torches and
may reach double the allowed limit.
It is essential for an expert coordinator to use measuring
instruments to determine whether there is a risk, and to
be able to adopt adequate safety measures as indicated
in section 7.9 of theEN 60974-9:Apparatusfor arc welding

ifthesurfaceisnothorizontal(e.g.slopedorbrokenooring,
etc...) the welding machine can topple.
- IMPROPER USE: it is dangerous to use the engine-driven
welding machine for any purpose other than that for which it
is intended (e.g. defrosting piping from the water system).

2. INTRODUCTION AND GENERAL DESCRIPTION
Diesel engine-driven welding machine for MMA electrode welding in
DC direct current. Can be used with many different electrodes: rutile,
basic, cellulose, stainless, aluminium, cast iron, etc. It can be used as
a single-phase and three-phase AC generator for powering all types
of electric tool (e.g. sanders, drills, dowel drills, demolishers, etc.),
compressors, neon and incandescent lighting systems, etc.
ACCESSORIESSUPPLIEDONREQUEST:
- MMA welding kit
- Wheel kit.
3. TECHNICAL DATA
Data plate
The main data regarding engine-driven welding machine performance
and use are given briey in the characteristics plate with the following
meaning:
Fig. A
1- Serial number for engine-driven welding machine identication
(essential for servicing, requesting spare parts, searching for
product origin).
2- Symbol representing the internal structure of the engine-driven
welding machine, alternator.
3- U
0
: maximum loadless voltage.
4- A / A: indicates the welding current adjustment range (minimum-
maximum).
5- Welding circuit performance:
- I
2
: Currents that can be supplied by the welding machine
during welding.
- X : Intermittence ratio: indicates the time during which the
engine-driven welding machine can supply the corresponding
current (same column). Expressed in %, on the basis of a
10-minute cycle (e.g. 60% = 6 minutes work, 4 minutes rest;
and so on).
If the use factors (referred to a room temperature of 40°C)
are exceeded, the thermostatic safeguard cuts in (the
engine-driven welding machine remains in stand-by until its
temperature returns within the permitted limits).
6- Casing protection grade.
7- Sound power (or pressure) level guaranteed by the engine-
driven welding machine.
8- EUROPEAN Standard of reference for safety and for the
construction of arc welding machines.
9- Symbols that refer to safety regulations, the meanings of which
are given in chapter 1 “General safety regulations”.
10- Auxiliary power output:
- Nominal output voltage (V).
- Nominal output power 1ph (single-phase) and/or 3ph (three-
phase).
- Cosφ.
11- Nominal frequency.
12- Internal combustion engine characteristic data:
Note: The meaning of the symbols and gures given in the example
plate shown are indicative; the exact values of the technical data
of the engine-driven welding machine in your possession must be
looked for directly on the plate of the machine itself.
