FILTER CARTRIDGE

Solar cell POWER AUTO ON/OFF Battery power consumption is minimized by supplying power from the solar cell of welding arc, which allows extended use of battery. Its auto power ON/OFF function through solar cell provides enhanced usability
ARC Light Detection Photo Sensor
Auto-darkening welding filter The welding filter of the hightest optical class (1/1/1/1) safely blocks harmful rays (UV,IR) of the welding arc and protects the welder's eyes comfortably and safely with a fast shading speed of 1/25,000 seconds.

Sensitivity Control

Ensures top welding performance by optimizing sensor sensitivity through four sensors installed according to various types of welidng environment and it makes welding easy by preventing light intererence from surrounding welding work or lights
Shade Control

Shade level can be adjusted in 5 level from #9 to #13 according to welding type and current (welding ARC)
Delay Control

Allows welders to maintain comfortable vision by preventiong eye fatigue from remaining head after thick plate welding and maintaining shade during fast tack welding by delaying the brighteniong speed
