The new VIKING™ 3350 Series  auto-darkening welding helmets from Lincoln Electric   feature top-quality LCD optics for a clear, natural view in varied ambient light settings. The solar-powered helmets, augmented with a user-replaceable lithium battery, have a substantial 3.34-in. height viewing area in a U.S. standard 5.25- x 4.50-in. sized cartridge shell. VIKING helmets  are ideal for stick, TIG, pulsed TIG, MIG, pulsed MIG and flux-cored welding, as well as gouging and grinding. An internal switch allows users to toggle shade control between 6-9 or 10-13 for handling plasma cutting up through heavy plate welding. Internally mounted controls also can be used to pre-test helmet/battery condition before welding.
 
Continuously variable delay allows users to vary how quickly the helmet returns from a darkened view back to a light state, while continuously variable sensitivity makes the helmet adaptable to different welding environments and lighting conditions. The helmets have four independent arc sensors that help users avoid blind spots, which otherwise could prevent auto-darkening.
 
Weighing in at 21 oz. (602 g), the VIKING 3350 helmets are lighter in weight than many auto-darkening helmets. Additionally, the helmet’s “grind mode” control allows it to be used as a grinding shield for weld prep or post-weld clean-up activities.
