How harmful is tin smoke? Application of soldering fume hood
Have you ever seen clouds of white smoke rising from where welders are working? That is soldering smoke. Inhaling this smoke for a long time can cause many respiratory diseases, even lung cancer. Faced with this urgent problem, the soldering fume hood was born. So how does the machine operate? Let's find out in the article below!

What is soldering fume?
When welders work, they use very high temperatures to melt tin and join metal parts together. This process creates clouds of white smoke, filled with tiny particles of tin dust and other chemicals.
Imagine that when you light a candle, smoke will rise, carrying melted wax particles. The soldering process is similar, the high temperature causes the tin to evaporate and form tiny dust particles, along with other chemicals that mix together to form smoke. That is why soldering smoke is not only white but also has a characteristic smell.
Harmful effects of soldering fumes?
Tin dust is microscopic particles produced from the soldering process, which is a potential threat to human health. When inhaled, tin dust will enter the lungs, causing respiratory diseases and can spread to other organs, causing serious damage.
In particular, organic tin is highly toxic, easily entering the body through many ways and causing dangerous diseases. Long-term exposure to tin dust can lead to many serious health consequences, affecting quality of life and reducing life expectancy.
Therefore, the use of smoke filtering devices and compliance with safety measures are extremely important to protect the health of workers and the working environment.
The role of the soldering iron?
Are you curious how this machine works? Actually, it works quite simply. The machine will create a strong suction force, sucking all the toxic smoke inside. Inside the machine, super clean filter layers will retain all dirt and toxic substances, returning fresh air to the workspace.
Welding fume extractors operate on the principle of creating a low pressure area at the location where the smoke arises, thereby sucking all the welding fumes into the duct system. Smoke will pass through filter layers to remove dust and other pollutants. Depending on the type of machine, the filter layers can be HEPA filters, activated carbon or electrostatic filter layers.
Welding fume hoods are divided into two main types:
- Mobile welding fume extractor: Compact in size, easy to move, often used in small factories or mobile welding jobs. This type of machine often uses HEPA filters to filter dust.
- Fixed welding fume extractor: Has a large capacity, permanently installed in one location, often used in large production factories. This type of machine often uses electrostatic filtration technology to remove dust with high efficiency.
Benefit:
Health protection: Minimize the risk of respiratory diseases such as bronchitis, asthma, and lung cancer.
Increase labor productivity: A clean, airy working environment helps workers work more effectively.
Environmental protection: Minimize air pollution.
Regulatory compliance: Ensure compliance with regulations on labor safety and environmental protection.
