The principle of a double-arm welding fume purifier: It uses top air intake and bottom exhaust. By utilizing the downward force of airflow, the double-arm welding fume purifier directs dust backblown from the top filter element toward the internal ash storage box. The mobile double-arm welding fume purifier’s suction arm is articulated like a human arm. This practical double-arm welding fume purifier can hover anywhere in space, and the suction hood can rotate 360 ​​degrees. This allows the suction hood to face the welding position at any position, facilitating welding operations and ensuring high welding fume efficiency. The suction arm also utilizes a universal interface, allowing for convenient use with various suction hood types. An air damper is designed near the suction port to adjust the air volume of the suction arm to the appropriate size. The double-arm welding fume purifier consists of a housing, filter cartridges, ash storage box, fan, dust cleaning device, and controller.

Features of double-arm welding fume purifier:

1. It adopts anti-overload circuit to prevent the motor from burning out, with high reliability and stable working performance, and is equipped with ABB turbine fan and motor.

2. Adopt built-in centralized PLC control mode, which is easy to operate and has a simple structure.

3. It can absorb dust particles below 0.3μm, has a good filtering effect on wet and sticky dust, and the filter cartridge is made of high-quality materials with a long service life.

4. It can remove smoke from the place where smoke is generated, thus improving the smoke collection rate. The universal suction arm that can move 360 ​​degrees freely is used to protect the health of operators.

5. The double-arm welding fume purifier adopts three protection measures to prevent fire hazards and large particles of slag, which makes the purifier have a long service life.

6. To facilitate the free movement and positioning of the equipment, it is equipped with a new Korean universal foot with a brake.

7. The consumables in the purifier have stable performance and are easy to replace.

After the smoke enters the body, some is excreted through feces and sweat, while the remaining toxic gases dissolve into the bloodstream after several hours. Through the bloodstream, these substances can invade the brain’s nervous system, leading to nutrient and oxygen depletion, dizziness, fatigue, and, in severe cases, lifelong disability. Most welding fumes and their inorganic compounds are low-toxic and generally pose no significant short-term risk to the human body with proper protection. However, prolonged exposure can affect the respiratory and digestive tracts, some can damage the skin and mucous membranes, and a few can cause neurotoxicity. Typical symptoms of tin poisoning include difficulty breathing, a dry cough, and impaired work ability. In severe cases, nausea, skin ulcers, and neurotoxicity can occur.

Since welding fumes are so harmful to the human body, those working in welding environments should strengthen their protective equipment. Commercially available welding fume purifiers are specifically designed to treat the fumes generated during welding. Toxic gases pass through the filtration system within the welding fume purifier, achieving a purification efficiency exceeding 90%. Therefore, for healthy working practices, please choose the right purifier.
