3 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.

Duty cycle percentage. The duty cycle expresses the percentage of 10 minutes during which
the welding machine can run at welding current I2.
Up
High-frequency ignition voltage for TIG process.
U2
Secondary voltage with I2 current.
U1
Rated supply 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.
IP23S
Degree of housing protection.
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
