2. Sensitivity adjustment:
choose the appropriate sensitivity, not only realize the anti-interference capability , but also
achieve better work.
(1)、when welding current is small , you need to put the "sensitivity"knob to high place, so you
can detect weak stable arc;
(2)、when welding current is big, you need to put the “sensitivity”knob to low place,
You can avoid the arc interference by others;
(3)、sensitivity is stepless control, set by hand according to actual situation
3. Delay time:
Delay time is time from dark to light , Stepless control.
(1)、When welding current is big and the light of molten pool is very strong , you need to put the
“delay”knob to high place , so you can avoid the glasses to be wounded by the light of
molten pool.
(2)、If you want to do spot welding, you need to put the “delay”knob to low place , so you can
improve the work efficiency.
(3)、Adjust “delay”knob to middle place is suitable for most of welding mode.
VII. Precautions for Use of Helmet
1. Before using the auto darkening welding helmet, please first tear off the films attached to the
inside and outside PC screening glass of the window, adjusting the tightening knob between
headband and helmet body, and then adjust the headband diameter and depth properly for
wearing;
2. Test with standard incandescent lamps of 40W or above before using , the liquid crystal will turn
black when you put lamps near it;
3. Do not put the helmet on any high-temperature weld joint after welding;
4. Do not take the helmet as safety helmet;
5. Replace unclear or damaged inside or outside screening glass timely to ensure the lines of sight;
6. In order to protect the product from damage, please do not clean it with clear water or cleaning
solvent; please use soft tissues or cloth for cleaning;
7. In order to ensure proper working of the auto darkening filter, please keep the sensors of weld arc
on it clean and out other objects;
8. When the ambient temperature is relatively low, the liquid crystal materials in the cartridge may
become a little retardant while it has no influence on various protective properties.
