cess and welding amperage to make primary
welding for test ( Seeing the Shade Guide Ta -
ble ). If the shade of filter is too darkening or
too light, please adjust the Shade Knob slightly
to correct position till the eyes can see the
welding spot which is not glaring and can see
welding molten pool. Please kindly note that it
will damage the eyes if using welding helmet

the: darkening speed is slow or the filter is flash, for such abnormal work, please find
the rea-son immediately. If operator can not solve the problem, please must stop
using the helmet immediately and contact with the dealer in time!

adjusted, time of filter from dark state to light
state, avoid the damage to eyes from the re -
sidual arc of welding molten pool due to too
fast switching time to light state when welding
is end (Break arc). The delay time is 0.1s-1.0s
The switching time may vary due to different
welding types and different sensitivity setting

tion.
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.
