3M Speedglas 9100 V

3M ™ Speedglas ™ Welding helmet 9100 with side windows. Includes 3M Speed Speedglas kaz 9100V welding cartridge: variable dark shade 5, 8, 9-13 for most types of arc welding. Exhaled air is led out through the side vents. Reduces the likelihood of the welding cartridge fogging. Ergonomically shaped head cross that specifically prevents pressure on vulnerable areas of the head. And it provides many different combinations of settings, so you can "tailor-make" the hood to suit you as much as possible and fit you comfortably, while increasing the stability of the helmet.
