New ESAB Sentinel A50 welding helmet offers advanced functions to increase operator comfort and productivity

novembris 24, 2017

ESAB Welding and Cutting Products has now introduced the new Sentinel™ A50 Air high-performance automatic welding helmets This expands the offering following the introduction of the Sentinel A50 welding helmet earlier this year. The Sentinel A50 Air incorporates a PAPR (Powered Air Purifying Respirator) unit.

The Sentinel's radical design incorporates ergonomic headgear and maximum adjustability to increase productivity, functionality and usability. The Sentinel A50's high-tech features include an almost infinitely adjustable 5-point headgear, a 100 x 60mm viewing area, an externally activated Grind Button, a colour touch screen control panel and a front-loading convex cover lens that comes in different colour options and changes in 10 seconds (see video).

"The technology involved mirrors the technology we use everyday, such as on our smart phones," says Guy Shelverton, Global Product Manager, ESAB. "Operators can now use this technology to make their lives easier and more productive in the workplace."

Operators will immediately notice greater comfort from the Sentinel A50's Halo™ adjustable 5-point headgear. The ergonomic, low-profile design delivers improved weight distribution with five contact points, including a central pivot point that allows maximum head clearance while the helmet is in the up position. The additional contact points introduce approximately 500,000 different combinations of headgear settings, five times more than standard helmets typically provide.

In addition to the enhanced headgear, the Sentinel A50 features an advanced high optical class ADF lens with a 100 x 60mm viewing area for wider visibility and better spatial awareness. With its 1/1/1/2 optical class rating, welders can be assured that the Sentinel A50 offers a sharp, clear and consistent view of the weld puddle. True colour technology enables operators to obtain a better view of the weld puddle and surrounding area, helping the operator keep the weld puddle centered in the joint.

High Functionality

For grinding, a grind application mode is activated externally on the shell's temple, so operators do not have to remove the helmet when shifting from welding to grinding. The grind mode is easily accessed, as well as deactivated, by holding the button for two seconds. With an external grind mode button, operators minimise downtime by quickly switching applications without having to access an internal switch on the control panel.

The Sentinel A50 features a convex front-loading cover lens that not only prevents the buildup of spatter, but also can be easily removed and replaced. The cover lens, as the chief consumable on a welding helmet, takes the most abuse during welding; consistent spatter, sparks and heat create wear and tear on the lens and prevent proper viewing. The spherical quick-release cover lens contains two switches — one fixed, one push-button — for one-click removal. Replacement can be achieved in 10 seconds, minimising any time spent changing parts. The spherical shape of the cover lens also reduces the small recesses and gaps where spatter collects and penetrates, particularly in overhead welding.

Operators will appreciate the Sentinel A50's full touchscreen with color backlit display that makes it easy to read in low-light environments. The helmet's interface is sharp, intuitive and accessed with only one button. The simple interface design permits operators to pick up the helmet, turn on the screen and activate everything without requiring a user manual.

The helmet's digital lens technology also gives the welder full control to adjust shade (5 to 13) and sensitivity. The interface contains eight memory settings with precision for any application or process. The Sentinel A50 weighs 640 g and features a high impact resistant nylon shell. The Sentinel A50 has the best combination of performance features and price.

Full Line of PPE

In addition to the Sentinel A50, ESAB will display its line of personal protective equipment and welding accessories, including heavy-duty welding gloves, flame retardant jackets and coveralls, spectacles and goggles and a variety of welding and cutting accessories.
