Result: the source voltage will pulse from 14.4 V to 21.6 V at a frequency of 20 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 voltage pulse time and the voltage "pause" time:
default
"duty cycle" [dut] = 50% "duty cycle" [dut] = 20% "duty cycle" [dut] = 70%
The unit will react in such a way that the average voltage level during the welding
process will be at the level of the set basic value of the welding voltage of 18V (as it was
set), respectively, and the heat input to the welding seam will be at the level of the same
18V, but the stability of the welding process, the mixing of the weld pool and penetration
will change. This is a very important condition for the user to accurately estimate the
amount of change in the heat input to the weld pool, e.g., by comparing it with another
main voltage without pulse mode.
If the task is to reduce the heat input to the seam by using a pulse mode, e.g., when
welding thin metals, then it is enough to reduce the main source voltage in a standard way,
while the amplitude of pulses and pauses set earlier will automatically adjust to this
voltage. Therefore, the user will clearly understand how much the current heat input to the
seam has decreased compared to the previous mode, while simultaneously changing, in
any combination, the power and "duty cycle" of the pulses to obtain the desired process.
This task is not easy, since several parameters are regulated at once.
These parameters are set in different situations in different ways, according to the
welder ’ s requirements. See paragraph 6.1 to change the value of any function in the current
welding mode
6. CONFIGURING THE UNIT
When the buttons on the front panel are not touched, the unit always displays the
value of the main parameter of the used welding mode on the digital indicator:
1) in the MMA mode – welding current;
2) in the TIG mode – welding current;
3) in the MIG/MAG mode – welding voltage.
Buttons 2 on the front panel are responsible for changing the value of the selected
function or main parameter.
Button 3 on the front panel of the unit is multifunctional and is responsible for the
following:
1) circular selection of any function in the current welding mode (quick press);
2) reset all functions to the factory settings of the current welding mode (hold for
more than 12 seconds).
