LSC
Low Spatter Control
LSC process: prevent spatter - reduce rework
Extraordinary welding results require innovative solutions: the LSC process ensures high arc stability and low spattering.
For maximum stability: the LSC process really plays to its strengths, especially with short circuit transfer. This process is based on the early detection of short-circuit incidents and enables the soft reignition of the arc at a low current level, ensuring maximum stability throughout the welding process.
Our high-end TPS/i and iWave welding systems quickly detect process conditions during the short circuit, allowing them to react just as quickly. In combination with the penetration stabilizer, users are able to achieve extraordinarily stable results.

Standard short circuit transfer vs. LSC short circuit transfer: reducing weld spatter and rework
The short circuit is triggered at a low current level, resulting in a stable welding process.
Standard short circuit transfer
Excellent results can be achieved with the controlled standard arc. But why settle for the standard when virtually spatter-free welding is possible?
LSC short circuit transfer
The digital resonant intelligence ensures an absolutely stable arc.
The benefits
- Up to 75% less spatter
- Reduction of rework
- Fewer rejects
Arc characteristics: the right characteristic for every application
Root welding reimagined: downward welding made possible by LSC root
Up to now, the root pass usually had to be welded in an upward position in the conventional short circuit arc.
In the downward position, there was a risk that a lack of fusion would occur. Typically, this was caused by the low arc pressure as the weld pool advanced. In contrast, the LSC Root characteristic means that welding can now be carried out in a downward position thanks to the high arc pressure. With LSC Root Advanced, a rate of 25 cm/min in a downward position can even be achieved.

Penetration stabilizer - constant penetration with penetration stabilizer
With an activated penetration stabilizer, the welding system readjusts the wire speed instead of the welding current, thereby ensuring constant penetration.
An additional wire control keeps the current and penetration constant if the distance between the welding torch and the component changes. As a result, the arc becomes much more stable and the penetration is always constant.
