Characteristics that can be selected using the Eln
function
(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 (4) is selected
(8) Example of pre-set arc-force dynamic where
characteristic (5) or (6) is selected
“con” parameter (constant welding current)
- 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 gouging.
- For arc air 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 (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.
NOTE!
When setting a flat characteristic (5), set the arc-force dynamic to a higher value.
“P” parameter (constant welding power)
- If the “P” parameter is set, the welding power is kept constant, irrespective of the
welding voltage and welding current. This results in a hyperbolic characteristic (6).
- The “P” parameter is particularly suitable for cellulose electrodes.
NOTE!
If there are problems with a rod electrode tending to "stick", set the arc-force
dynamic to a higher value.
