4.3 WELDING CURRENT BUILD-UP FUNCTION
This function, in addition to saving the life of the electrode and, to some extent, the
torch itself, is also necessary for the convenience of using the torch. This eliminates the
formation of initial splashing of the weld pool, as well as for the set time of current build-up
[t.uP], you can accurately direct the torch to the desired welding location, since the arc
striking location in particularly critical workpieces is not always located at the welding
location, or you can even use this function to preheat the welding location. By default, it is
set to OFF
– disabled. See paragraph 6.1 to change the value of any function in the current
welding mode
4.4 PULSE CURRENT WELDING FUNCTION
This function is designed to facilitate the control of the welding process in spatial
positions other than the lower one, as well as when welding non-ferrous metals. The effect
occurs directly on the mixing of the molten metal of the seam, and this, in turn, on the
stability of the seam formation. To some extent, it replaces the movement of the welder's
hand during welding, especially in hard-to-reach places. There is also partially a forced
effect on the transfer of a drop from the filler wire to the weld pool. The correct setting
determines the shape and quality of the seam formation, which reduces the likelihood of
pores and reduces the grain structure, and thus increasing the strength of the welded joint.
To implement this function in the device, you need to set three parameters: pulsation
power [Po.P], pulsation frequency [Fr.P] and pulse/pause ratio (or "duty cycle") [dut]. By
default, pulsation power [Po.P] as a key parameter is set to OFF, i.e., the function is turned
off, and pulsation frequency [Fr.P] and "duty cycle" [dut] at the most common values of 10
Hz and 50%, respectively. To enable the function, simply set the pulsation power [Po.P]
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 2 mm, the
set basic value of the welding current is 100A, and the pulsation power [Po.P] = 30%, while
the pulsation frequency [Fr.P] = 10.0 Hz and "duty cycle" [dut] = 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" [dut] = 50% "duty cycle" [dut] = 20% "duty cycle" [dut] = 70%
The unit will react in such a way that the average current level during the welding
process will be at the level of the set main value of the welding current 100A (as it was set),
respectively, and the heat input to the welding seam will be at the level of the same 100A,
