4 Arc Sensors
Maintain constant sensing and automatically switches the helmet from light to dark and back again.

Enhanced Viewing Area
Offers a larger viewing area for the operator. This larger viewing area enhances the operators view of the welding area

True Colour
High Definition Filter Technology is a feature that greatly improves the optics allowing the user to see a full
spectrum of colours. It also helps to alleviate eye fatigue making it safer for extended periods of welding.

Operator Comfort
Lightweight Design makes wearing the welding helmet more comfortable for the operator.

Memory Function
Allows the operator to store different shade, sensitivity and delay options into three easily accessible pre-sets.

Grind Mode
Allows the operator to switch the helmet from the welding mode into a fixed shade for grinding.
This function removes the need for the operator to change visors and to simply use the welding helmet for grinding
when required.

Shade Control
Automatic Welding Lens allows the operator to switch
between variable welding shades from 5-9 and 9-13.
The switching speed of the lens is a very fast 0.04m/s from light to dark.
