Indicates the percentage ratio of the welding current
strength direct current (DC) to the main current I1.
If the value set is 50, the DC current strength is 50% of the
main current I1.
Downslope
A synchronisation takes place in the DC pulse operating
mode with feed or control The current reduction always
begins with I2 independent of the current status I1 or I2.

Indicates the percentage ratio between main current I1 and
auxiliary current I2. If the value set is 30, the ratio is 30 %
I1 to 70 % I2.
Tab. 3: Main parameters
The factory setting values are optimised thanks to auto-
matic parameters.
You can use these factory settings unchanged for most
LED/
welding jobs.
