This welding helmet has a large viewing area of 2.18 × 4.2 inches and has one of the biggest lenses you will ever find in a welding helmet. The helmet is quite comfortable, especially for your ears, and there are times when we lose awareness that we are using a helmet. The helmet is quite durable hence making it ideal for industrial uses. Exhaust vents on the sides, channel out the exhaled air, thus preventing the build-up of moisture and fogginess. The ergonomically designed head suspension is another positive.

Arc Sensors:

The versatility of the helmet allows it to be useful in different welding processes like arc welding ok, MIG welding, TIG welding, etc. This is achieved by treating sensitivity adjustments. The auto-darkening feature is under the control of three Arc sensors which are responsible for changing the shade from light to dark in a small time span of just .1 millisecond. The sensors can detect instantaneously when the arc is struck, immediately chatting the transition from light to dark shade. Once the arc has been struck, the helmet goes back to light shade 3 within 250 ms minimizing your downtime.

Shade Settings:

By activating the filter you can change the sensitivity level. The helmet provides a total of 7 different shade modes. They range from 5 to 6 and 9 to 13. You can check the current shade setting, by clicking the “shade on” button. If needed you can choose a new shade setting by pressing the shade button while flashing and selecting the desired shade level. Now, hold the button for two seconds.

Sensitivity level one and two are for normal used Level three is used for current welding while four finds application in TIG welding. Level six is the darkest shade.
