Please kindly note that it will damage the eyes if using welding helmet under incorrect
shade no.(too darkening or too light) for a long time.
3) Sensitivity Knob: Before welding, please adjust the sensitivity to high position, if
encountering the interference of Lighting lamp(the filter is darkening while not
welding), please adjust the sensitivity towards low position slightly until the filter
returns to light state (please don’t make the helmet towards to light lamp source
during this process, should towards to welding workpiece). During welding, the
sensitivity knob should be adjusted as high as possible, or it will affect the darkening
speed of filter. Attention: Operator must stop using the helmet immediately and
contact with the dealer in time if the filter can not be darkening or the darkening speed
is slow or the filter is flash.
Attention: If the filter can not be darkening or the darkening shade is not enough or
the darkening speed is slow or the filter is flash, for such abnormal work, please find
the reason immediately. If operator can not solve the problem, please must stop using
the helmet immediately and contact with the dealer in time.
4) Delay time Knob -- It can adjust the switching time of filter from dark state to light
state, avoid the damage to eyes from the residual arc of welding molten pool due to
too fast switching time to light state when welding is end (Break arc). The delay time
vary from 0.3s to 0.9s. The switching time may vary due to different welding types
and different sensitivity setting even delay time handle is at the same position. If the
filter is flash under low current welding, please adjust the delay time handle to long
position, this can help to solve this problem.
