2.INTRODUCTIONANDGENERALDESCRIPTION

200AACVERSION

Petrol engine-driven welding machine for MMA electrode welding in

(AC) alternate current. Electrodes: rutile. It can be used as a single-

phase AC current generator for powering all types of electric tool

(e.g. sanders, drills, dowel hole drills, demolishers, etc.) and electric

devices (e.g. lights, saws, compressors, etc.).

300ADCVERSION

Petrol or diesel engine-driven welding machine for MMA electrode

welding in (DC) direct current. It 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 current

generator for powering all types of electric tool (e.g. sanders,

drills, dowel hole 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.

3- 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).

4- EUROPEAN Standard of reference for safety and for the

construction of arc welding machines.

5- Symbols that refer to safety regulations, the meanings of which

are given in chapter 1 “General safety regulations”.

6- Nominal frequency.

7- Internal combustion engine characteristic data:

- n : Rated load speed.

8- Casing protection grade.

9- Sound power (or pressure) level guaranteed by the engine-

driven welding machine.

10- Auxiliary power output:

- Nominal output voltage (V).

- Nominal output power 1ph (single-phase) and/or 3ph (three-

phase).

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.
