"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 arc air gouging.
- For arc air gouging, set the arc-force dynamic to "100".
Parameter "0.1 - 20" (drooping characteristic with adjustable slope)
- Parameter "0.1 - 20" is used to set a drooping characteristic (5). The setting range ex -
tends 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 weld -
ing 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 dy -
namic to a higher value.
