All parameter set values that have been set by means of the adjusting dial (1) will remain
stored until the next time they are changed. This applies even if the power source was
switched off and on again in the interim.

HotStart function

To obtain optimum welding results, it will sometimes be necessary to adjust the HotStart
function.

Function
During the specified hot-current time (Hti), the welding current is increased to a certain
value. This value is 0-100% (HCU) higher than the selected welding current (I
Example: A welding current (I
a value of 50% has been selected. During the hot current time (Hti, e.g. 0.5 s), the actual
welding current is 200 A + (50% of 200 A) = 300 A.

"con" parameter (constant welding voltage)
If the "con" parameter is set, the welding current will be kept constant, irrespective of the
welding voltage. This results in a vertical characteristic (4).
The "con" parameter is especially suitable for rutile electrodes and basic electrodes, as
well as for arc air gouging. The "con" parameter is therefore also the factory setting when
the "MMA welding" process is selected.
For arc air gouging, set the arc-force dynamic to "100".
"0.1 - 20" parameter (drooping characteristic with adjustable slope)
Parameter "0.1 - 20" is used to set a drooping characteristic (5). The setting range
extends from 0.1 A / V (very steep) to 20 A / V (very flat). Setting a flat characteristic (5)
is only advisable for cellulose electrodes.
