For protection purposes, the Migatronic optical welding helmet Focus ADF and Focus MigADCplus can be equipped with a hard hat with brakes with built-in springs to keep it in place in irrespective of welding position. The heavy-duty construction ensures long life of hard hat and adapter. If the welder stops welding, he can easily dismount the welding helmet, even with welding gloves on, and still be protected by the hard hat.
