power as a key parameter is in the OFF, i.e., the function is disabled, and the pulsation
frequency and duty cycle are at 10.0Hz and 50%, respectively. To enable the function, simply
set the pulsation power above zero. This parameter is set as a percentage of the used main
welding current set.
Example: Welding with a refractory tungsten electrode with a diameter of 2mm, the set main
value of the welding current is 100A, and the pulsation power is 30%, while the pulsation
frequency is 10.0Hz and the duty cycle is 50% by default.
Result: the current will pulse from 70A to 130A at a frequency of 10 Hz; the pulses will have
an equal shape in amplitude and time.
The "duty cycle" parameter is set to 50% by default. Changing this value introduces an
asymmetry between the current pulse time and the current "pause" time:
default
"duty cycle" = 50% "duty cycle" = 20% "duty cycle" = 70%
At the same time, the unit will react in such a way that while maintaining the
specified pulse difference, the average current level will be maintained during the welding
process at the level of the set main value of the welding current 100A (as it was set earlier),
respectively, and the heat input into the weld will be at the level of the same 100A, but the
stability of the welding process and the mixing of the weld pool will change. This is a very
important condition for accurate user assessment of the quality of change with equal heat
input into the weld pool.
These parameters are set in different situations in different ways, according to the
welder’s requirements.

The unit can act as a source for semi-automatic welding, and it has the necessary
current-voltage characteristic at the output of the power terminals when switching to this
mode.
