2.5 Connection of Cooling Water and Assist Gas
2.5.1 Connection of Cutting Gas
The impurity in cutting gas such as hydrocarbon and steam will damage the lens and cause cutting power fluctuation as
well as inconsistencies between the sections of the work piece. The table below is the recommended cutting gas
specification. The higher the purity of the gas, the better the quality of the cutting section.
Impurity can be filtered out in gas supply tube, but Oxygen and water vapor can permeate light path through nonmetal
materials, which is the source of the appearance of dust and hydrocarbon. Stainless steel fittings are recommended, at
the same time must use filters which can remove a minimum of 0.01 micron particle to purify.
A pressure gauge with a stainless steel diaphragm is recommended. Industrial pressure gauges suck in air. Rubber
diaphragm produce hydrocarbon by aging or other factors.
CAUTION: Gas interface cannot be replaced arbitrarily especially do not use PTFE TAPE. Otherwise the gas
path will be blocked and cannot do normal cutting which will damage cutting head at the same time.
