Attention must be paid to the maintenance and use of oxygen hoses and acetylene hoses to keep the hoses clean and free from damage. Avoid exposure to the sun, rain and snow, and prevent contact with substances that may damage the hose, such as acids, alkali, oils, etc. The storage temperature is -15℃~40℃, and the distance should not be less than 1 meter.
When using the new hose, the talcum powder on the inner wall of the hose must be blown out to prevent the passage of the welding torch from being blocked. During use, avoid external pressure and mechanical damage, and do not fold the hose.
Oxygen and acetylene hoses must not be mixed and replaced with each other. Do not use the oxygen hose to blow out blockages in the acetylene hose. At the same time, check and eliminate defects such as air leakage and blockage of the torch at any time to prevent the formation of a mixture of oxygen and acetylene in the hose. If a flashback occurs and fuel enters the oxygen hose, the hose is no longer usable and must be replaced with a new tube. Because tempering often burns out the conditioned tube, compressed pure oxygen is a strong oxidizing agent. If you continue to use it, you will lose the normal security.
Gas cutting operations require a large amount of oxygen output, so the valve of the ear tube (or oxygen pipeline) connected to the high-pressure side of oxygen should be fully opened to ensure sufficient flow and stable pressure. Although the low-pressure gauge has shown the working pressure, the pressure suddenly drops when oxygen is used. At this time, backfire is likely to occur, and the oxygen hose may be transferred to cause an explosion.
