ESAB's new automatic helmet, the Sentinel A50Click image to enlarge

ESAB has developed a new automotic welding helmet that incorporates ergonomic headgeaur and adjustablity to increase productivity, functionality and useability, claims the company.

The Sentinel A50's features include an infinitely adjustable 5-point headgear, a 100 x 60 mm viewing area, an externally activated Grind Button, a color touch screen control panel and a front-loading convex cover lens that comes in different color options and changes in 10 seconds.

"Operators can now use this technology to make their lives easier and more productive in the workplace, says Guy Shelverton, global product manager, ESAB.

Operators will notice greater comfort from the Sentinel A50's Halo™ adjustable five-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 color 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.

For grinding, a grind application mode is activated externally on the shell's temple, so operators don't 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 minimize 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, minimizing 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. An anti-scratch coating reduces the reflection from high exposure to spatter and sparks.

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 28 oz. and features a high impact resistant nylon shell.
