Full details of the welding tool with oxygen hwan?
Oxygen pressure 0.1 ~ 1MPa, filling pressure < 15MPa; Pressure from acetylene pressure 0.01 ~ 0.06 MPa, the pressure inside the bottle < 1.6 MPa; The pressure on the gas meter is usually labeled as MPa, sometimes as kg/cm2, and an MPa is equal to 9.8 kg/cm2; Generally start with acetylene, then you will see a yellow flame, relatively weak combustion and smoke, then open another oxygen flame will gradually change the blue white, and from the beginning to soft of the flame gradually shrink into the blade shape, then it can be used to heating turning tool and the blade, the workpiece burn and then fill in the red stick the flux of the copper wire, liquid copper wire is automatically along the aperture infiltration to the inside.
The oxygen cylinder should wear safety cap, firm on the fixed scaffold, the measures to prevent sun exposure. The oxygen in the oxygen cylinder should not be fully used, the remaining pressure must be left, and the anti-acetylene reverse irrigation will cause the explosion. Oxygen cylinders with residual pressure should be tightened and marked with "empty bottles". When the oxygen cylinder attachment is defective, the valve screw slip should be stopped. 4, use the hand and tools of the oil to operate the cylinders in case of an explosion.
The oxygen cylinder should not collide strongly. It is prohibited to unload or carry out any other method of collision. The electromagnetic crane is strictly prohibited. When opening the bottle valve and the reducer, people should stand on the side. The speed of the open process is slow, preventing the temperature of the organic material from being too hot or the airflow too fast to produce static spark. And it causes combustion. 7, in winter, the cylinder pressure reducer and piping freeze occurs, it is forbidden to use fire baking or use of things like iron slam cylinders, more can't fierce screw adjusting screw decompression table, to prevent all of a sudden a lot out of oxygen, cause an accident. The oxygen cylinder should not be close to the heat source, and the distance from the open fire should not be less than 10 meters. 9, use an oxygen cylinder without a decompression device. The compressor should be repaired by professional personnel.
