“con” (constant welding current) parameter
-If the “con” parameter is set, the welding current will be kept constant, irrespective
of the welding voltage. This results in a vertical characteristic .
-The “con” parameter is especially suitable for rutile electrodes and basic electrodes,
as well as for gouging.
-For gouging, set the arc- force dynamic to “100”.
Parameter “0.1 - 20” (falling characteristic with adjustable slope)
-Parameter “0.1 - 20” is used to set a falling characteristic . The setting range
extends from 0.1 A / V (very steep) to 20 A / V (very flat).
-Setting a flat characteristic is only advisable for cellulose electrodes.
Important! When setting a flat characteristic , set the arc-force dynamic to a higher
value.
“P” parameter (constant welding power)
-If the “P” parameter has been set, the welding power is kept constant, irrespective
of the welding voltage and welding current. This results in a hyperbolic characteristic
(Fig. 23).
-The “P” parameter is particularly suitable for cellulose electrodes.
Important! If there are problems with a rod electrode tending to “stick”, set the arc-force
dynamic to a higher value.
