TACKLIFE Welding Helmet, Large Viewing Area(3.94"x2.87"), Top Optical Clarity (1

Description

Product Description
Offer best protection for your eyes!
1. Top Optical Clarity 1/1/1/1:
Actual test grade 1/0.6/1/0.6 An integer required by Certification Standard, actual optical performance is better.
2. Full Shade Range:
Passive Filter with Permanent shade 13 to UV/IR, combined with three-layered auto dimming LCD shutter for best eye protection, providing sufficient and full shade range within
3/3-8/9-13
(not just 4/5-9/9-13).
3. Super Large View Area:
3.94"x2.87" inch / (100 x 73 mm), provides more clear and bright field of view and good ventilation.
4. Four Premium Arc Sensors:
offering
super-fast switching time (switch from light to dark in 1/25000 seconds) and accurate auto shading can minimize radiant bypass, avoiding eye stress.
5. Comfortable Design:
There are multiple adjustment joints ensuring the helmet can fit your head perfectly, offering better comfort.
6. PA Material:
PA material is lighter, more durable and with better fire resistance than common PP material.
7. Full Face Neck Coverage:
protecting welders from spatters and harmful radiant.
8. Standard Meets:
EN 379 CE, ANSI /ISEA Z87.1,AS/NZS 1338.1,CSA Z94.3 safety standards.
About the strobe effect:
If the helmet has the stroboscopic effect, please adjust the sensitivity knob and the delay knob.
Decrease the sensitivity and delay the reaction time.
Better Light State: DIN 3
Different from many other brands, we have a DIN 3 light state (14% light transmittance) that enable users to see workpieces and environment clearer compared with normal light state DIN 4 (5% light transmittance).
Reduce Eye Strain
At light state, the filter shows yellow-green color, cut off harmful blue light to an extreme and reduce eye strain, as well as discomfort.
UV/IR Protection
The UV/IR protection up to 16 at all time. Higher number is on behalf of less penetrable UV/IR and higher optical grade. Higher the number, greater the protection.
Wide Application
A great personal protection equipment designed for industrial use that can handle multiple processes of Plasma cutting, abrasive wheel cutting/grinding, DC TIG, AC TIG, MIG/MAG, MMA/Stick welding, which are popular in metal fabrication industry, welding schools, welding shops, auto manufacturing and repair industry, ship factories as well as DIY hobbyists projects.v
Q&A
Q: What does "optical clarity 1/1//1/1" mean?
A:
The most important feature of an auto darkening welding helmet, next to comfort, is how well one can see through the lens. The term used to describe this feature is Optical Clarity. It's judged on four different metrics: Accuracy of Vision (Optical Class), Diffusion of Light (Light Scatter), Consistent Shade (Homogeneity) and Angular Dependence. The best rating for each of these metrics is a 1, the worst rating is a 3. Most helmets made by a well-respected manufacturer will typically score at least 1/1/1/3, and a high-end helmet will score a 1/1/1/2 and sometimes a 1/1/1/1. The last metric, angular dependence, is typically the most difficult to reach a perfect score. This has too much to say. If you want to know more about it, google it, you can learn a lot.
Q: Why does it flash accidentally?
A: Pls check, did you decrease the sensitivity and delay the reaction time when you don't use it? And remember to put back the welding helmet into the bag comes with. If you skip these steps, the battery may be dead soon.
Q: Where could I buy outer replacement lens?
A: The lens are standard size. You could buy replacement lens very easily.
