Example: when welding with a 2mm non-consumable tungsten electrode, the set
main welding current is 100A and the pulsing power is 30%, with a pulsing frequency of
10.0Hz and a default "duty ratio" of 50%.
Result: The current will pulse from 70A to 130A with a frequency of 10Hz. The pulses
will have the same shape in amplitude as in time.
The "duty ratio" parameter is set to 50% by default. If you change this value, it
introduces an asymmetry between the current pulse time and the current "pause" time:
By default
"duty ratio" 50%
"duty ratio" 20%
"duty ratio" 70%
The machine will calculate that while maintaining the set pulse difference, the
average welding current will be maintained at the main welding current of 100A (as set),
respectively the heat input to the weld will be the same as 100A, but the stability of the
welding process and the mixing of the weld pool will change. This is a very important
condition for the user to accurately estimate the amount of change in the weld pool's heat
input.
These parameters are set up differently in each situation, according to the
requirements of the welder. To change the value of any function in the current welding
mode, see section 6.1.
5. SEMI-AUTOMATIC WELDING (MIG/MAG)
Warning!
Carbon dioxide "CO2" is used as safety gas when welding ferrous metals
in the simplest case, and when welding aluminum, only inert gases such as argon "Ar",
sometimes expensive helium "He", as an alternative for stainless and high-alloy steels
mixtures in different proportions "80%Ar+20%CO2" are often used. The use of other gases
must be coordinated with the manufacturer of the equipment.
Warning!
Since the machine uses a standard KZ-2 EURO type connector for the
torch, you can subsequently purchase a torch of your choice.
