GRAPHIC - Auto Darken WELDING HELMET:The automatic welding helmet is a new generation product for labor protection. Some new and high science and technology such as LCD, optoelectronic detection, solar power, microelectronics, etc are integrated into it. The automatic welding helmet not only can efficiently protect operator's eyes from injuries caused by arc, but also can make both hands free and strike arc accurately. Therefore, the quality of products and work efficiency may be raised considerably. It may be widely used for various welding, cutting, spraying and arc gouging, etc.

UMGWH automatic welding helmet is equipped with a filter set that can become dark. The filter is transparent before welding, so the operators may observe the work surface clearly. When striking arc, the filter darkens automatically immediately. When arc goes out, the filter will become transparent again. The switching time from light to dark is about 0.0001 second. The switching time from dark to light may be set up within 0.1-0.9 second. The mask is equipped with continuous darkness-adjusting unit, so the operator may select an arbitrary dark shade number ranging from No.9 to No.13.

UMGWH automatic welding gives the operators permanent complete protection against UV/IR even in transparent condition. The UV/IR protection level is up to DIN13 in all time. The power is provided by solar cells, so user is exempted from changing battery, turning on or off power and any other operation.
The mask is equipped with 2 sets of photo sensors to sense arc light. In addition, the helmet is also provided with an outer protection plate made of high polymer materials. The plate is wear-resistant, thermo-stable, and has no dregs-sticking, thus a very long service life.
