Sentinel™ A70 PRO

For welders who don’t back down.

The Sentinel A70 PRO is built for the realities of heavy industry, long shifts, harsh conditions, and nonstop sparks. A wide-open view and precise digital control put you in command, while the flip-up design and oversized grinding shield keep you working without missing a beat.

When the light’s low, the integrated work light cuts through the dark, and rugged protection shields your head and neck where it matters most. Powered for endurance and connected for control, it’s a helmet built to match your pace, tough, reliable, and ready for the grind.

Because in heavy industry, your gear must work as hard as you do.
