Piercing

Normal piercing

Normal piercing is optimized for fast, reliable processing. The beam remains ignited until the end of the piercing time.

Advantages: Normal piercing depending on the gas type:

Oxygen: Start hole is produced with minimal time delay.
Nitrogen: Producing the start hole with nitrogen prevents formation of oxides when starting to cut

Gentle piercing

Gentle piercing usually takes a little longer than normal piercing; however, it delivers better quality piercing results.

Defined settings possible in combination with a ramp.
Minimal amount of slag or molten metal being thrown up.
When cutting small contours in stainless steel, a start hole is produced with a small amount of material. This reduces nozzle wear and the increase process reliability.

Multistage piercing

Piercing with up to three independent piercing parameter sets. This makes possible pre-treatment and refinishing of the piercing possible, which means, for example that the amount of thrown-up material around the piercing can be greatly reduced.

Area of application: material thicknesses from 10 mm in mild steel, stainless steel and aluminum.

PierceLine piercing sensor

Safety margins have been added to the piercing time in the cutting tables to ensure process reliability. This is necessary above all because the shortest possible piercing time varies depending on the technology, with variation as follows:

From piercing to piercing.
Depending on the quality of the material.

The piercing-end is detected by the piercing sensor, PierceLine, and the piercing process is ended as soon as the material is completely cut through. Thus considerably reducing the piercing time.
