eters
“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.
"Minimum" and "maximum" are used for setting ranges that differ according to power
source, wire-feed unit, welding program, etc.
Anti-stick
Unit -
Setting range ON / OFF
Factory setting ON
As the arc becomes shorter, the welding voltage may drop so far that the rod electrode
will tend to stick. This may also cause the rod electrode to burn out.
Electrode burn-out is prevented by activating the anti-stick function. If the rod electrode
begins to stick, the power source immediately switches the welding current off. After the
rod electrode has been detached from the workpiece, the welding process can be contin-
ued without any problems.
