Functions
- First-class 3-in-1 automatic welding helmet with integrated respiratory protection system and a P3 particle filter in accordance with filter protection class TH3 P R SL.
- Intelligent air filtration with integrated control module for stable and consistent air supply in three stages: 170L/min, 200L/min, 230L/min.
- The fresh air unit's 14.8 volt Li-ion battery can be conveniently charged using the mains adapter supplied. There is no need to change the battery. The operating time is up to ten hours, depending on the air flow rate.
- Equipped with a true color filter cassette of the latest generation, the professional welding helmet guarantees optimum visibility and excellent true color reproduction.
- Four independent sensors ensure that the welding shield is automatically darkened as soon as the arc ignites. An ambient light sensor is used to adjust the darkness levels to the arc brightness.
- Thanks to the convenient remote control with Bluetooth connectivity, numerous parameters (WELD / CUT / GRIND / DARK MODE) can be easily selected without having to take off the welding helmet.
- The various darkening levels can be set from DIN 4 to DIN 14 depending on the mode by turning the push button. Precise fine-tuning can be carried out using the SHADE function of the filter cassette.
Features & benefits
- An integrated job memory saves welding parameters for later applications and is another system highlight.
- For welding in constrained positions, the welding helmet has an innovative locking protection to prevent accidental adjustment of the dimming levels.
- For short welding cycles such as tack welding or spot welding, the automatic welding helmet has an additional TACK mode specially adapted to the process.
- The large field of vision of the filter cassette provides an optimum overview of the work area and workpiece.
- Thanks to numerous adjustment options, the welding helmet's premium headband adapts perfectly to the shape of the head and ensures an optimum fit.
- Thanks to the visor seal, neck protection, face cuff and flame-resistant chin guard, the helmet remains tight, safe and comfortable to wear.
- The combination of automatic darkening of the field of vision, color fastness and intelligent air filtration enables safe, controlled work and makes this welding helmet system the ideal choice for professional welders and demanding craftsmen.
