Optrel Helix Pure Air 2.5 ADF Welding Helmet 2.5/5-12

Manufacturer: Optrel

• The Optrel Helix Pure Air 2.5 ADF welding helmet and hard hat features an internally mounted slide up ADF with a non-reactive shade level of just 2.5, giving welders a brighter and clearer view of the workpiece and their surroundings. The unique Optrel Helix slide up concept, allows the welder to choose the protection required for each application with a single turn. Complete welding tasks with the auto darkening filter down and proceed to grinding and sanding applications by simply sliding the ADF up inside the helmet, revealing a totally clear visor with 180° viewing area. The Optrel Helix Pure Air is equipped with a PAPR adapter so that it can be used in conjunction with the Optrel PAPR respiratory protection system e3000X. Clean fresh air is channelled directly into the helmet, where it circulates around the head, protecting you perfectly whilst at the same time keeping you pleasantly cool and thus meeting the highest levels of air filtration and respiratory protection possible during welding, cutting, and grinding applications.

  Unlike other flip up welding helmets that place the auto darkening filter on the outside, the Optrel Helix uses an internal sliding system which allows the ADF to remain inside the clear grinding visor. Not only does this protect the ADF from weld spatter and scratches, it also dramatically reduces the ongoing replacement lens costs, as only one outer protection lens is required as opposed to two on other flip up designs. When the ADF is fully retracted, it is positioned on top of the head so the welding helmet remains perfectly balanced, this is in contrast to other flip designs which cause the helmet to be front heavy which can lead to neck and head strain.         

  Shadetronic ® The patented Optrel Shadetronic technology features on the entire Helix range of welding helmets. It is of critical importance that the correct shade is selected in order to provide the adequate protection when welding. Unfortunately, this process is often neglected meaning that shade levels are never adjusted, compromising performance and safety. Shadetronic sensors permanently measure the intensity of the welding arc, regulating the level of protection automatically across the entire range of shade levels from 5-12 . Optimal protection is achieved without ever needing to adjust the welding helmet. Shadetronic technology is ideal for hot start at the beginning or during the crater fill, slope out at the end of the welding process, or simply when welding with different current strengths.

  Fadetronic is patented Optrel technology which manages the ADF’s changes from dark to light after the welding process has been completed. This eliminates the unpleasant afterglow associated with slope out or high-ampere applications. Eye fatigue is significantly reduced thanks to the fluid opening of the display, allowing the eyes to adapt back to light more gradually.

  The Helix range has a total of 5 arc sensors – one central and four corner mounted, ensuring the auto darkening glare shield is activated and deactivated perfectly, even in the most difficult lighting conditions and positions during welding.

  The unique and environmentally friendly Optrel re-charge energy concept ensures that the welding helmet remains charged and ready for use. Thanks to the latest solar technology, a rechargeable lithium-polymer battery is recharged by welding light or ambient light. In addition, the battery can also be charged directly with any USB charger via a micro-USB interface. Battery replacement is avoided and the environment is protected.

  Sensitivity Function prevents the ADF lens from being prematurely activated in certain lighting environments or if a number of welders are working in close proximity. The Super High sensitivity setting can used if the welding current is extremely low preventing the ADF from activating.

  The shells of the Helix range of welding helmets are compact and feature a smoke and particle repellent shape, making them suitable for overhead welding applications.

  The Helix range comes fitted with Optrel IsoFit® headgear, the ultimate in wearer comfort. The IsoFit cradle is the only head band available that enables the wearer to adjust width, length, and height simultaneously, with the turn of a single rotary wheel. An ingenious cable hoist system expands and contracts to give a glove like fit, applying equal pressure at every contact point. This ensures there is no pinching, slipping, or chafing, offering unrivalled comfort and practicality.

  IsoFit is the perfect companion if you have to weld for long periods of time or need to work in multiple positions and want the helmet to remain in place. Despite the headband or cradle being the interface between the helmet and the wearer, it is often overlooked by manufacturers and users alike. The Optrel IsoFit headgear system combines technology and comfort, resulting in improved productivity and safety in welding applications. Optrel IsoFit ®  can be dismantled in just a few seconds and cleaned with soap and lukewarm water to maintain hygiene.

  The hard hat fitted inside Helix welding shields is an industrial safety helmet meeting EN 397 standards. The hard hat can quickly and easily be removed should it no longer be required.

  The compact size and shape of Helix helmets allows the welder to work in constrained environments such as when working inside vessels, unless the oxygen content in the breathing air is too low (Europe: <17%, Australia:

  <19%) or if the toxin concentration is so high and a higher protection class than TH3P is required.

  For respiratory protection use in conjunction with Optrel e3000X PAPR system which has been designed to work flawlessly with Helix Pure Air welding helmet range.
