3�2 Lock protection
If the welding machine malfunctions, a WARNING message may appear on display screen A. This identifies the type
of defect. If the message is still present after turning the machine off and on, contact the assistance service.
3�3 Thermal protection
This device is protected by a thermostat which prevents the machine from operating if the allowable temperatures are
exceeded. In these conditions, the fan continues to operate and the display screen A shows the message WARNING
tH in flashing mode.

Serial number, to be indicated on any request regarding the welding
machine.
Single-phase static frequency converter transformer-rectifier.
Three-phase static frequency converter
Suitable for MIG/MAG welding.
Suitable for TIG welding.
Suitable for MMA welding.
Secondary open-circuit voltage.
Duty cycle percentage. The duty cycle expresses the percentage of 10
minutes during which the welding machine can run at welding current I2.
Secondary voltage with I2 current.
Rated supply voltage
50 or 60-Hz single-phase power supply.
50 or 60-Hz three-phase power supply
Max. absorbed current at the corresponding I2 current and U2 voltage.
This is the maximum value of the actual current consumed, considering
the duty cycle. This value usually corresponds to the capacity of the fuse
(delayed type) to be used as a protection for the equipment.
Degree of housing protection.
Grade 3 as the second digit means that this device may be stored, but it is
not suitable for use outdoors in the rain, unless it is protected
Device suitable for use in locations with increased electrical risk
