After properly adjusting the head gear, determining the height at which the helmet will sit on the head, and positioning the helmet inward, towards the face, or outward, away from the face...I found the following:
A. Ear coverage is not good enough, especially when welding in positions that produce reflected arc light, such as in a box, tank, or around structures where you must move into reflected arc light in order to complete a weld. Slight turns of the head can lead to arc light exposure.
B. A helmet bib is necessary, as light leaks in from under the neck area, even with the work directly in front of your position. Yes, shielding the arc with the nozzle is a remedy, but this is not a natural technique.
C. Using a half-mask respirator with this helmet, barely fits and makes the design even more problematic, as you must move the helmet outward to it's max position.
D. Design is too tall and narrow, allowing arc light in from all open directions, where reflection occurs.
E. The lens works perfectly, two sensors is adequate for the work I do. The sensitivity to any light flash, is pretty remarkable even at the lowest setting.
In closing, I would not buy this hood again or recommend it, because the coverage it is designed to provide is not good enough for my demands. I have added work arounds to the design: helmet bib from ear to ear, and a bonnet from the top to the back of the head gear. The 370 head gear is nice, the lens is good, the helmet shape is too minimal. Sure, suiting up like a NASCAR driver would cover all issues of skin exposure, but not reflected arc light back into the hood from behind, sides or neck area.
ProsAdequate lens clarity, and sensitivity. The ease of swapping out protective covers. 370 head gear is comfortable without add-ons.
ConsToo tall, and narrow. Also lacks adequate coverage for neckline and ears.
