Why is it necessary to use a welding fume extractor?

During the welding process, a large amount of smoke and dust is produced. Under the high temperature of the electric arc, nitrogen molecules in the air can be directly oxidized into nitrogen oxides, which are 4 to 5 times more toxic than NO. When they come into contact with water, they can turn into nitric acid or nitrous acid, causing strong irritation. Workers inhaling high concentrations of nitrogen oxides can suffer from acute asthma or develop emphysema. Long-term chronic exposure can lead to symptoms of neurasthenia and chronic respiratory tract inflammation.

The carbon monoxide in welding mainly comes from the decomposition of carbon dioxide, so a large amount of carbon monoxide gas is produced in CO2 shielded welding. In other arc welding processes, only a small amount of carbon monoxide gas is produced. When fluorine-containing welding materials are involved in the welding process, a small amount of HF gas can be generated. HF has a strong irritant effect.

These harmful substances are produced and float in the air, invading the human liver, lungs, cardiovascular system and blood through the respiratory tract, seriously eroding human health and leading to the occurrence of many occupational diseases, such as lung cancer, asthma, eczema, bronchitis, skin allergies, respiratory tract infections, etc. In severe cases, it can disrupt the central nervous system, damage the digestive system, and cause complications leading to death.

The correct selection of industrial air purification equipment is an important decision for every enterprise. The health and safety of employees are matters of great concern, and production profits also depend on this choice.
