Exento — MIG/MAG torches with welding fume extraction and retrofit kits
Country: Austria · Model: Exento
Exento MIG/MAG torches with built-in fume extraction cover five power classes, from 250 to 500 A. The fume is captured at the arc before it rises to the welder's face and spreads through the workshop, so both the welder and everyone working nearby are protected. The range complies with DIN EN ISO 21904-1 and complements the Exento HighVac and HighVac Duo high-vacuum units.

Description
The MTG 250i Exento at 250 A and the MTG 320i Exento at 320 A, both at 40 % duty cycle, and the MTG 400i Exento at 400 A at 30 % duty cycle have gas cooling. The MTW 300i Exento, which carries 300 A at 100 % duty cycle, and the MTW 500i Exento at 500 A at 40 % duty cycle have water cooling. The welder adjusts the extraction rate directly on the handle, and the suction nozzle has a quick draught check. LED lighting helps in dark places and when inspecting the weld, and a 1.3 m leather sleeve near the handle protects against heat and spatter. The torch is larger than a standard one, so the handle ergonomics have been worked out separately to keep the welder from losing pace. The Exento kit retrofits MIG/MAG torches, including all PushPull models, and the special nozzle geometry captures the fume without disturbing the gas shielding.
How to choose
The torch class is selected by current and duty cycle, as for a standard MIG/MAG torch. For long welds at 300 A the MTW 300i Exento with 100 % duty cycle is suitable; for shorter cycles up to 500 A there is the MTW 500i. The interface is chosen from four options: Up/Down, JobMaster, potentiometer or top button. If you already have a torch fleet, the Exento kit will retrofit the torches without replacing them, and Up/Down and JobMaster will work as before.

FAQ
Do Exento torches comply with the standards for welding fume?
Yes, Exento torches with extraction comply with DIN EN ISO 21904-1 “Occupational health and safety in welding and allied processes”.
Can fume extraction be added to a robotic torch?
Yes, a separate Exento kit is available for robotic torches, in which the extraction nozzle sits directly on the gas nozzle.
How does the lighting work after the Exento kit is installed?
The lighting in the kit depends on the position of the extraction channel, and the nozzle itself is smoothly adjustable to the weld.
For what work is extraction through the torch most needed?
For manual MIG/MAG welding in workshops where occupational health standards for fume must be met, especially when welding stainless steels and during long work.
