2 GENERAL DESCRIPTIONS

2.1 SPECIFICATIONS
This welding machine is a constant current generator built
using INVERTER technology, designed to weld with
covered electrodes and for TIG procedures, with contact
starting.
IT MUST NOT BE USED TO DEFROST PIPES, START
ENGINES AND CHARGE BATTERIES.
2.2 EXPLANATION OF THE TECHNICAL SPECIFI-
CATIONS LISTED ON THE MACHINE PLATE.
This machine is manufactured according to the following
international standards: IEC 60974.1 - IEC 60974.3 -IEC
60974.10 CL. A - IEC 61000-3-12 - IEC 61000-3-11
N°. Serial number, which must be indicated on any
type of request regarding the welding machine.
Single-phase static transformer-rectifier
frequency converter.
Drooping characteristic.

supply
I1 max. This is the maximum value of the absorbed
current.
I1 eff. This is the maximum value of the actual current
absorbed, considering the duty cycle.
IP23S 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.
S
Suitable for hazardous environments.
Note:
1- The machine has also been designed for use in
environments with a pollution rating of 1. (See IEC 60664).
2.3 DESCRIPTION OF PROTECTION DEVICES
2.3.1 Thermal protection
This machine is protected by a temperature probe, which
prevents the machine from operating if the allowable
temperatures are exceeded. In these conditions the fan
continues to operate and display screen A shows the
message Err. 74. .
2.3.2 Motor-driven generators
These must have a power equal to or greater than 8KVA
and must not deliver a voltage greater than 260 V.
50- or 60-Hz single-phase power
