7. COMMON PROBLEMS AND REMEDIES
Irregular Darkening Dimming
Headgear has been set unevenly and there is an uneven distance from the eyes to
the lter lens.(Reset the headband to reduce the di erence to the lter ).

1. Front cover lens is soiled or damaged (please change the cover lens)
2. Sensors are soiled/blocked or solar panel is blocked(Clean the sensors surface to
make sure you are not blocking the sensors or solar panel with your arm or other
obstacle while welding)
3. Sensitivity is set too low or delay time is set too short(Adjust to required level)
4. Make sure proper shade is selected (not Grind mode)
The Filter Darkening Without Arc Being Struck
Sensitivity set too high(Adjust Sensitivity to a required level)
The Filter Remains Dark After Completing A Weld
Delay time set too long(Adjust Delay time to a required level).
Slow Response
Operating temperature is too low(Do not use at temperatures below-10°C or 14°F).
