Unit - / A/V / -
Setting range I-constant / 0.1 - 20.0 / P-constant

(1) Load line for rod electrode
(2) Load line for rod electrode where
arc length is increased
(3) Load line for rod electrode where
arc length is reduced
(4) Characteristic where "I-constant"
parameter is selected (constant
welding current)
(5) Characteristic where "0.1 - 20" pa-
rameter is selected (drooping
characteristic with adjustable
slope)
(6) Characteristic where "P-constant"
parameter is selected (constant
welding power)
(7) Example of pre-set arc-force dynamic where characteristic (4) is selected
(8) Example of pre-set arc-force dynamic where characteristic (5) or (6) is selected
I-constant
(constant welding cur-
rent)
- If the "I-constant" parameter is set, the welding current will
be kept constant, irrespective of the welding voltage. This
results in a vertical characteristic (4).
- The "I-constant" parameter is particularly suitable for rutile
electrodes and basic electrodes.
