Fume Extraction For The Welding Industry 

Our ‘Purex’ machines are designed with resilience in mind, providing a robust solution against the hazards of welding. Welding fumes, a known cause of occupational lung diseases, can be effectively managed with our machines. The use of Respiratory Protective Equipment (RPE) and Personal Protective Equipment (PPE) is always recommended when welding. However, our machines can further enhance safety by alleviating additional risks.

The welding process is when two or more metals are joined together using heat or pressure. When zinc is heated, melted or burned at high temperatures during the welding process, zinc oxide particles are released. These fumes emitted can be harmful when exposed to workers and can cause the following health risks: metal fume fever, skin irritation, fever and occupational lung disease. At Purex, our fume extraction systems efficiently remove hazardous welding fumes. Learn how our fume extractors can support your specific welding applications:

Typical applications

Arc welding

Arc welding, also known as stick welding, is the process of using electricity to generate heat to melt and join metals. This process releases welding fumes that contain chromium compounds which can be highly hazardous to the respiratory system. Taking protective steps, like effectively extracting welding fumes, is vital to ensure the safety of your team. 

MIG welding

MIG welding is the process of joining thick, large materials quickly and efficiently through welding. However, the metal, filler and substances that are used are often vapourised, creating toxic fumes and chemical smoke. This can displace oxygen and generate carbon monoxide gas at hazardous levels if adequate fume extraction is not present. 

TIG welding

TIG welding refers to joining a wide range of small, thin metals such as stainless steel. During this process, the molten metal releases harmful molecules of metal and Ozone that can displace oxygen, causing respiration issues, dizziness and nausea. A well-ventilated environment and proper fume extraction can mitigate the risks of exposure to create a safer working environment.
