I-constant (constant welding current)
-
If the "I-constant" parameter is set, the welding current will be kept con-
stant, irrespective of the welding voltage. This results in a vertical character-
istic (4).
-
The "I-constant" parameter is particularly suitable for rutile electrodes and
basic electrodes.
