Conical cut
1. If there is a false cut turn off the machine, release the shield cup and rotate
the cutting tip about 1/4 and again try to cut.
2. Damaged nozzle and electrode, replace b
3. The position of the torch is not perpendicular to the material.
4. Too large distance from the cutting tip to the material
Caution
If the electrode is fired deeper than 1.5 mm, it must be replaced.
Scale on the underside of the cut
1. High air pressure.
2. Damaged nozzle or electrode, replace both.
3. The cutting speed is not correct.
4. The distance between the torch and the cut sheet is not correct.
The life of consumables is short
1. High or low air pressure.
2. The set current, cutting speed and other parameters are not set
according to the recommendations of chapter 11-105 A - INDICATIVE
CUTTING PARAMETERS.
3. The piercing is performed from an inappropriate height.
4. Air quality is not good.
10. INDICATIVE PARAMETERS – CUTTING GAPS
The parameters in the table are for reference only. They were measured when
set to the highest cutting quality.
