INSTRUCTIONS FOR USE
1- Lithium/alkaline battery and solar cell power supply provides a service life of 5,000 hours, 15-20 minu-
tes with automatic closing function.
2- The internal or external control knobs can be used to manually select shades 9-13, sensitivity and
delay time control, welding/grinding functions.
3- Dual photoelectric sensor technology, high-quality dual LCD and fi lter provide the welder with a clear
fi eld of view and effective UV ray protection, up to grade DIN13.
4- Ultra-quick LCD darkening. The fi lter switch time from light to dark is no more than 1/1000s EN 379
(1/25000s, ANSI Z87.1) standard, so as to protect the eyes from arc damage.
5- In the LCD bright state, the degree of protection is DIN4; it takes 0.1-1.0s from dark state to bright state
when arcs disappear with sensors.
6- The operating temperature is -5 °C ÷ +55 °C.
7- Broad scope of applications - for example, manual arc welding, gas shielded arc welding and plasma
cutting.
8- Fully adjustable headgear, for increased comfort and reduced fatigue.
Operating instructions
1. Before welding, please make sure that:
1.1 the protective fi lm has been removed from the internal and external screen;
1.2 the power is suffi cient (fl at battery indicator in the helmet);
1.3 the protective fi lms are complete, the solar cell is not damaged or blocked by dust;
