Instruction:
(1) Open the package and take out the helmet. Remove the protective film on the viewing area.
(2) Adjust the tension of the comfort cushion through the manual knob so that the user feels comfortable after using it. It adopts self-locking function design. Press the button on the headband for a stretchy fit. IMAGE: 2
(3) Adjust the knobs on the sides of the helmet to change the tension when raising and lowering the helmet. The visual angle can be moved forward or backward as you need. IMAGE: 3,4
(4) Adjustable sensitivity and delay time of the display area according to different working conditions. Reduce the sensitivity to avoid interference. When a small current low arc is used, a high sensitivity can be selected. But high sensitivity should be adopted in the case of argon arc. The delay time is the moment when the filter changes from dark to light.
