The lightweight SWARM A20 welding helmet is a heavyweight when it comes to performance and flexibility. Using an advanced auto-darkening filter (ADF), SWARM A20’s externally selectable shade range from 9–13 tackles the most demanding welding applications. A handy grind setting, also found on the external knob, allows quick attention to finishing work. Further adjustments to delay and sensitivity settings can be made easily with dials inside the helmet.

With a streamlined shell design, 1/1/1/2 CE optical clarity, and replaceable, long-lasting battery – SWARM A20 is the perfect solution for welders looking to improve weld quality.
