(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 "CON" parameter is
selected (constant welding current)
(5) Characteristic where "0.1 -20" parameter is
selected (falling characteristic with adjustable
slope)
(6) Characteristic where "P" parameter is selected
(constant welding power)
(7) Example of pre-set arc-force dynamic where
characteristic (5) or (6) is selected
(8) Possible change in the current where charac-
teristic (5) or (6) is selected, as a function of
the welding voltage (arc length)
(a) Operating point where arc length is long
(b) Operating point when welding current IH is set
(c) Operating point where arc length is short
The characteristics (4), (5) and (6) shown here apply when using a rod electrode whose
characteristic corresponds - at a given arc length - to the load line (1).
Depending on what welding current (I) has been set, the point of intersection (operating
point) of characteristics (4), (5) and (6) will be displaced along the load line (1). The oper-
ating point provides information on the actual welding voltage and the actual welding cur-
rent.
Where the welding current (IH) is permanently set, the operating point may migrate along
the characteristics (4), (5) and (6) according to the welding voltage at a given moment.
The welding voltage U is dependent upon the length of the arc.
If the arc length changes (e.g. in accordance with the load line (2)) the resulting operat-
ing point will be the point where the corresponding characteristic (4), (5) or (6) intersects
with the load line (2).
Applies to characteristics (5) and (6): Depending upon the welding voltage (arc length),
the welding current (I) will also become either smaller or larger, even though the value
set for I
H
remains the same.
