Technology in detail
Ergonomic slide-up design
The Helix helmet has a distinctive sliding module that carries the auto-darkening filter. This mechanism opens up your field of view quickly and smoothly, without lifting or removing the whole helmet. The operator can switch in a moment from welding to grinding, weld inspection or material preparation while keeping full face protection and uninterrupted respiratory protection. The design keeps neck strain to a minimum and noticeably speeds up work cycles. It is an investment in ergonomics that pays off directly in less fatigue and higher efficiency over the whole working day.
Auto-darkening filter with a 2.5 light state
At the heart of the helmet is an advanced auto-darkening filter with a light state of 2.5. It is one of the brightest filters on the market and gives an exceptionally clear, realistic view of the surroundings before you start welding. This brightness makes it easier to position the torch precisely, see markings on the material and find your way around the work area, and it reduces eye strain. Better visibility means fewer mistakes and higher quality work from the very start. It is a key feature for professionals who care about every detail and precise execution.
Intelligent ShadeTronic® technology
ShadeTronic® technology works like a personal assistant for the welder, adjusting the shade to the intensity of the welding arc in real time. The system analyses the arc brightness and selects the optimum protection level within a defined range on its own, so there is no need for manual adjustment. Whether you are tack welding or welding at high current, the helmet always gives you the right shade. This intelligent automation lets you concentrate fully on the weld pool and your technique, an investment in consistent weld quality and reliable eye protection.
Certified TH3 class respiratory protection
The e3000X powered air system provides the highest possible level of respiratory protection, in line with the demanding EN 12941 standard (class TH3). This means that the high-efficiency particle filter captures as much as 99.8% of the harmful dust, fumes and aerosols produced during welding. Controlled positive pressure inside the helmet effectively isolates the welder's breathing zone from the contaminated outside air. It is a fundamental investment in your own health that protects against serious occupational diseases and keeps you safe in typical workshop conditions.
Three-stage airflow with cooling effect
The e3000X system offers three adjustable airflow settings: 170, 210 and 240 litres per minute. This lets you match the airflow precisely to the ambient conditions and your personal preferences. The highest setting (240 l/min) not only supplies the maximum amount of clean air but also gives a noticeable cooling effect on the face and forehead. This is a real advantage during intensive work at high temperatures. Adjustable airflow means thermal comfort and higher productivity, even in the most demanding industrial environment.
Integrated system with an 18h battery
The e3000X is designed as a closed, optimised system that is matched to the Helix helmet. Precisely designed air channels and a face seal distribute the air evenly without irritating the eyes. The kit comes with a high-capacity lithium-ion battery that allows up to 18 hours of continuous operation on a single charge. That is enough for two full shifts without breaks for charging. It is an investment in continuity and reliability that eliminates downtime and maximises productivity.
