TWIN Process Parameters
TWIN process pa-
rameters
The following TWIN process parameters are available at the power sources in TWIN mode
under Process parameters / TWIN process control:
- Wirefeeder
- Arc length correction
- Pulse/dynamic correction
- Penetration stabilizer
- Arc length stabilizer
- Pulse synchronization ratio *
- Lead/trail phase shift *
- Trail ignition delay *
* The following sections contain a detailed description of special process parameters
for TWIN mode.
Pulse synchroni-
zation ratio
Adjustment range: auto, 1/1, 1/2, 1/3
Factory setting: auto
The pulse synchronization ratio enables both process lines to be operated with significantly
different wire speeds.
In the case of greater differences in output, the pulse frequency is adjusted in such a way
that it differs between lead and trail by an integral multiple. Only every second or every third
pulse is then executed for the trail arc.
The characteristic for automatic ("auto") mode contains an optimum frequency ratio based
on the wire speed values for both process lines. The wire speed can be set separately for
each process line.
When setting the frequency ratio manually, the value can be set at both power sources in-
dependently. The value set at the lead power source is applied to the process.
1/1 Both arcs work with the same pulse frequency. The number of droplets per time
unit is identical in both process lines.
1/2 The trail arc works with half the pulse frequency of the lead arc. Droplet detach-
ment only takes place at the trail arc with every other pulse.
1/3 The trail arc works with a third of the pulse frequency of the lead arc. Droplet de-
tachment only takes place at the trail arc every third pulse.
