7. 4T-LOG
18. Selection for spot, synergic quickpulse and long pulse
19. Search arc 10 - 80% of welding current
20. Pulse current 10A - max.
21. Pulse ratio 10 - 70 % of pulse time
22. Frequency 0,2 - 300 Hz
23. Base current 10 - 70% of pulse current
24. Spot time 0 - 10 s
25. Tail arc 10 - 80% of welding current
7. Welding torch trigger 4T-LOG function (only MTX panel)
When torch switch is pressed current goes to search arc, after the switch is released current goes
to welding current within the up-slope time. When the switch is pressed again, current goes to
downslope and then to the tail arc. Current stops when the switch is released.
18. Spot
Spot function is practical when welding a definite spot. It can be used both in 2T and 4T. Enter
the spot time adjustment by pressing arrow button and when led lights you can choose the needed
spot time by turning pulse potentiometer.
18. Synergic quickpulse
Press the PULSE button twice and the synergic light turns on. Pulse parameters are automatically
calculated when mean welding current is selected. Other pulse selections are not necessary.
18. Long pulse
Long pulse method gives you a possibility to adjust all the pulse parameters (pulsing frequency,
pulse ratio, pulse current and pause current). You can also set the mean welding current which
results in a new pulse current value calculated using the set percentage values of pulse ratio and
pause current like when entering Pulse mode. When you adjust the pulse ratio percentage, pulse
current or pause current percentage a new mean welding current value is calculated and displayed
on the panel.
