Smoke hazard:
Welding fume is a kind of fume produced in the process of welding and when the electrode contacts with the weldment under the condition of high temperature combustion. This kind of fume contains manganese dioxide, nitrogen oxide, fluoride, ozone, etc. floating in the air will cause harm to human body. People work in this kind of high smoke environment for a long time. After inhaling a lot of smoke, it will cause dizziness, headache, cough, chest tightness, shortness of breath and other symptoms. Serious can lead to smoke poisoning or pneumoconiosis.
Equipment features: 
The equipment is equipped with universal casters, which can be flexibly moved in any position of the plant. The dust removal rate is high without the restriction of the dust source. The clean air discharged after treatment can be directly circulated and played in the workshop. The flexible single suction arm can hover at any position in the three-dimensional space. The 360 degree can easily and flexibly reach any position. The operation is simple, and easy to clean and maintain. It can be researched according to the special requirements of customers Make the order.
Features of single arm welding range hood:
1. Single arm welding range hood is a single dust removal equipment with only one suction arm.
2. It is equipped with special imported ABB turbine fan and motor, and adopts anti overload circuit to prevent motor from burning out, with high safety and stable working performance.
3. Pulse back blowing type automatic dust cleaning: the filter element adopts all-round automatic rotation back blowing to make the dust cleaning on the surface of the filter element more thorough and clean, which can always ensure that the dust collector has a constant air suction volume and that the purifier is always in good working condition.
4. The filter cartridge is made of imported materials from the United States. It has a long service life and can absorb dust particles below 0.3 μ M. it has a good filtering effect on wet and sticky dust.
5. The universal suction arm with 360 degree free movement can absorb and remove the flue gas from the place where the flue gas occurs, greatly improving the collection rate of the flue gas and ensuring the health of the operators.
6. In the 1500 air volume single arm welding range hood, three protection measures are adopted for the hidden fire hazard and large particles of slag, so that the service life of the purifier is longer, safer and more reliable.
7. The clean air is evenly guided and dispersed from the grid like air outlet, thus reducing the noise to.
Working principle of the single arm welding fume machine: the welding fume purifier has four filtering levels, which can remove the welding fume thoroughly. Firstly, the welding fume enters the first layer of the equipment - air flow equalization plate through the suction arm. The uniform air flow distribution prevents the pollutants from concentrating in one main filter element direction. At the same time, it intercepts the sparks and prevents the occurrence of fire. Then the gas enters the second layer - prefilter, which initially filters the polluted gas and the service life of the soot filter element. The gas after prefiltering enters the third layer --The core filter cartridge filter has a filtration efficiency of%, which can purify most of the welding fume; the post filter is used after the gas, so that the purified gas can enter the breathing area, and can be recycled for energy conservation and environmental protection
