The use of a CNC flame cutting machine is extremely important for cutting gas, and the daily maintenance and troubleshooting of the tracheal gas circuit of the equipment also need to be paid attention to.

1. Trouble repair of the gas system

There are two main aspects of common gas path maintenance. In addition to frequently checking the gas path system and discovering leaks and parts that cannot be used normally, they should be handled in time to ensure that the gas path is unobstructed; the dust and debris of the gas path should also be cleaned frequently. Prevent premature aging of the gas circuit.

2. Trouble repair of pressure reducing valve

For the maintenance of the pressure reducing valve, the pressure reducer should be adjusted first, and the pressure gauge should be adjusted to the required pressure. During the adjustment process, the pressure should be adjusted from small to large to ensure that the pressure reducer can be continuously adjusted. If continuous adjustment is not possible or gas leaks from the safety valve, a new pressure reducer must be replaced. Folding the parts of the gas pressure reducer by yourself will cause equipment damage and even serious personal injury.

3. Maintenance of the tempering preventer

The tempering preventer is an important part to ensure safety. According to the requirements of the security department, the tempering preventer is strictly prohibited to be disassembled without permission. Therefore, the air resistance of the tempering preventer is used for a long time, and the gas flow cannot be guaranteed or the air leakage is not guaranteed.

4. Breakdown and maintenance of torch nozzle

In the purchase of accessories, we recommend that users use the original machine provided by the manufacturer. During the long-term use, the sealing surface of the cutting torch is damaged, and the sealing with the cutting nozzle is not strict and must be repaired with special tools. In addition, the cutting torch also uses the standard rapid cutting nozzle produced by professional manufacturers. For the new cutting nozzle, it must be qualified before it can be used. The cutting nozzle is contaminated. Special tools are required to clean the preheated flame hole and cut the oxygen channel.
