FAQ
Why do other companies have higher results on airborne welding fume extraction?

Kemppi’s welding fume extraction gun models and their extraction efficiency has been measured according to new standard, ISO 21904-3. Our test results are always verifiable and transparent. 

The Flexlite GF offers primary protection for not only the welder, but also for others sharing the same working environment. The efficient and adjustable vacuum flow removes 95% of airborne fumes and particles before they reach breathing zones. 

Why doesn’t Kemppi reccommend any vacuum devices?

Kemppi informs the user about the recommendable minimum and maximum flows to be used with Flexlite GF fume extraction guns. With this information, the correct vacuum unit is easy to select. In addition, the adjustment in Flexlite GF models helps in dealing with different vacuum flows. With an additional air flow meter, it is easy to determine the current vacuum flow

Why should I select a fume-extracting welding gun?

A fume-extracting welding gun, such as Flexlite GF, is the most mobile choice that removes welding fumes right from the source. Welding jobs are often carried out in inaccessible places. The excellent ergonomics of the lightweight Flexlite GF reduces injury risks and allows a welder to weld for longer periods of time, and more efficiently. With the Flexlite GF, welding performance can reach new levels in terms of safety and welding capability.

Grip on safety – an efficient fume extraction MIG gun series

The Flexlite GF product series consists of several MIG/MAG welding guns with a fume extraction function. The efficient vacuum system extracts the welding fumes directly from the gun nozzle without disturbing the shielding gas flow, thus providing a safer and cleaner working environment for the welder as well as for others sharing the working environment.

The Flexlite GF fume extraction gun is available in water- and gas-cooled versions. All Flexlite GF fume extraction gun models offer Flexlite features for user comfort, welding efficiency, and extended consumable part life.

The Flexlite GF provides a safer working environment. The product series has been tested against the new ISO 21904-3 standard. This ensures a standardized way to prove the capture efficiency of the gun. The standardized welding gun is a safe and reliable tool for a welder’s day-to-day work.

Excellent ergonomics and usability are distinguishing features of all Flexlite products. The detachable pistol grip handle and a well-balanced gun shape make the welding work smoother, meaning the gun is a delight to hold. The detachable pistol grip handle also makes the welding position more natural and ergonomic.

Fume-extraction guns are the only solution that removes welding fumes right at the source. As well as maximum protection, the Flexlite GF also results in premium welding work. With the help of a high-performance gun, the power source capacity is used efficiently, and spatters are minimized.
