9100/9100FX Optimise your welding comfort, coverage and control with 3M Speedglas 9100 or 9100 FX Air Welding Shields. They feature a head suspension system that profiles your unique head shape for a secure, stable fit and readily connects to 3M powered and supplied air respirator systems, the 9100FX also provides constant TH3-rated respiratory protection as well as excellent visual clarity in the flip-up mode. Lifted into the raised position, the shield's "high point" is lower than many other shields. The smooth up-and-down pivot action can be "locked" in the up position - a light pull lowers the shield back down again. The Speedglas 9100 Series offers a choice of auto-darkening filters with outstanding optical quality and adjustability for precise, tailored view of your work. ***Air Supply and Welding Filter supplied separately.
