GENERAL DESCRIPTIONS

This welding machine is an inverter power source. It is suitable for TIG welding with contact ignition and high frequency,
and for MMA welding with the exception of cellulosic electrodes. The power source is built according to IEC 60974-1,
IEC 60974-3, IEC 60974-10 (CL. A), IEC 61000-3-11 and IEC 61000-3-12 standards.

Explanation of plate data

No.
Serial number, to be indicated on any request regarding the welding machine.
1
Single-phase static frequency converter transformer-rectifier.
3
Three-phase static transformer-rectifier frequency converter.
MMA Suitable for welding with coated electrodes.
TIG Suitable for TIG welding.
U0 Secondary open-circuit voltage.
Duty cycle percentage. The duty cycle expresses the percentage of 10 minutes during which
X
the welding machine can run at welding current I2.
High-frequency ignition voltage for TIG process.
Up
Secondary voltage with I2 current.
U2
Rated supply voltage.
U1
50 or 60-Hz single-phase power supply.
1~ 50/60Hz
3~ 50/60Hz 50 or 60-Hz three-phase power supply.
I Max. current absorbed at the corresponding current I
1max
This is the maximum value of the actual current consumed, considering the duty cycle. This
I value usually corresponds to the capacity of the fuse (delayed type) to be used as a protection
1eff
for the equipment.
Degree of housing protection.
IP23S
Grade 3 as the second digit means that this machine 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
