During the welding process, the apparent clarity of the material can be very clear to observe the solder joints to ensure the quality of welding effect.2. Novel design, super lightweight, durable shell.3. Double filters to avoid the ultraviolet and infra-red harmful radiation generated by the arc, as well as the damage to the eyes caused by the welding glare.4. Reliable dimming, dimming time less than 1/10000 seconds5. Advanced filter technology, light transmission uniformity, clear imaging6. When not sensitized, the shading number is 3, providing sufficient light for preparation and precise grinding.
