- 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

against the engine-driven welding machine (minimum

ADDITIONAL PRECAUTIONS

- WELDINGOPERATIONS:

 - Inenvironmentswithincreasedriskofelectricshock;

 - Inconnedspaces;

 - Inthepresenceofinammableorexplosivematerial;

 MUST ALWAYS be evaluated in advance by an “Expert

supervisor”andmustalwaysbecarriedoutinthepresence

of other people trained in emergency procedures.

 The technical protection means described in sections 7.10;

A.8;A.10.of“Part9:Installationanduse”ofthe“EN60974-9:

Apparatusforarcwelding”DirectiveMUSTALWAYSbeused.

-Welding should NEVER be allowed if the operator is above

- VOLTAGE BETWEEN THE ELECTRODE HOLDERS OR

TORCHES: when working with more than one welding

machine on a single piece, or on several pieces that are

connectedelectrically,dangerousno-loadvoltagesmaybuild

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

RESIDUAL RISKS

- TOPPLING:positiontheengine-drivenweldingmachineona

horizontalsurfacethatissuitableforsupportingtheweight;

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).

- The only permitted way to lift the machine is described in the

“INSTALLATION”sectionofthishandbook.

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

: maximum loadless voltage.

4- A / A: indicates the welding current adjustment range (minimum-

maximum).

5- Welding circuit performance:

- I

: 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.
