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.
