The UNIMIG PRO SERIES DEMON is a professional-grade auto-darkening welding helmet designed for welders requiring superior eye protection and enhanced visibility during welding tasks. It is suitable for various welding applications, providing reliable safety and comfort.

This welding helmet features a 1/1/1/1 optical clarity classification, ensuring a crystal-clear view of the weld from every angle. The large 102.5 x 102.5mm viewing area offers unmatched visibility, allowing welders to monitor their work with precision. The auto shade select technology automatically detects the welding arc and adjusts the shade level to protect the eyes without manual intervention.

Additional benefits include a 3.0 light state for clear visibility before, during, and after welding, and an external grind button that enables quick switching to grind mode with an LED indicator. The helmet is equipped with five arc sensors (four arc sensors plus one arc intensity sensor) for instant arc detection, providing consistent protection even when welding out of position.

The helmet is powered by solar cells with two replaceable CR2450 backup batteries to ensure reliable auto-darkening filter performance. Comfort is enhanced by a 4-point adjustable harness that distributes weight evenly to reduce neck strain during extended use.
