22. Function descriptions
All functions are described below.
1. Display Volt / Ampere
By tapping on the button A / V, the display (item 6) can be switched between current (A) and voltage (V).
2. Welding process
DC Machine:
By tapping on the button welding process, it is possible to switch
between:
LED 21 – DC current with high frequency ignition
LED 22 – DC current without high frequency ignition
LED 23 – Electrode welding
The corresponding LED lights.
AC Machine:
By tapping on the button welding process, it is possible to switch between:
LED 20 – AC current with high frequency ignition
LED 21 – DC current with high frequency ignition
LED 22 – DC current without high frequency ignition
LED 23 – Electrode welding
The corresponding LED lights.
3. Welding mode:
By tapping on the button welding mode, it is possible to switch between:
The corresponding LED lights.
2-cycle (LED 30):
1.
By pressing the torch trigger, the welding process starts after the Gas
pre flow time with the starting current (Is). If a Slope-up time is set, the
current rises up with it to the main current I1.
As long as the torch trigger is pressed, the machine continues with welding.
2.
By releasing the torch trigger, the current goes down to the final current IE with the slope down time
SD (if set), and then the machine turned off. The gas post flow time is active.
4-cycle (LED 31):
1.
By pressing the torch trigger, the welding process starts after the Gas pre flow time with the starting
current
(Is).
As long as the torch button is pressed, the machine is welding with the starting current Is.
2.
By releasing the torch trigger, the current rises up with the Slope-up time (if set), to the main current I1.
3.

Current I2 (LED 32):

current
(Is).
As long as the torch button is pressed, the machine is welding with the starting current Is.
By releasing the torch trigger, the current rises up with the Slope-up time (if set), to the main current I1.
2.
Now, when the torch trigger is tapped shorter than 1 second, the machine switches to the secondary
current I2. Again tapping to the torch trigger shorter than 1 second, the machine switched back to the
main current I1. This process can be repeated as often as desired.
3.
Again pressing the torch trigger for more than 2

4.
Spot welding –only in 2-cycle mode (LED 33):
1.
By pressing the torch trigger, the welding process starts after the Gas pre flow time with the starting
current (Is). If a Slope-up time is set, the current rises up with it to the main current I1.
2. After the spot welding time is completed,
down time SD (if set), and then the machine turned off. The gas post flow time is active.
If the spot welding function is active (LED 33 is light), the spot time can be changed by tapping on the
function key (item 4). By rotating the knob (item 9) the time can be adjusted between 0,01 and
10 seconds. Finish the settings by long pressing the function key (item 4).
