Good Hood, but def needs some RE-engineering though
I purchased this welding hood about a year ago, it sat for about a month before I could get it mounted to a hard hat, which when I did, had to be customized a lot so that it would stay in the upright position, and not fall into my face. I called 3M personally and they said they could send me another hard hat adapter, which is the same hard hat adapter used on OLD SCHOOL fiber metal hoods, once again that do not work on this hood. So biggest disappointment is that the hood had to be customized quite extensively to work mounted on a hard hat, problem being that the width of the hard had does not allow the front to flip up correctly, and allow for ease of use.
Prosexcellent viewing area, periphrial view is a little tricky getting used to but is very nice to have when working on scaffolding and welding with other workers in near vicinity, ease of changing outside cover lens is also a plus.
Consdoes not mount to hard hat correctly, after getting it mounted for hard hat use the front lens does not flip up correctly, cleaning the inside of the auto shade is next to impossible unless you take out the grinding shield to reach "through" the grinding shield to wipe excess dust and debris off the inside of the auto shade. changing the grinding lens and inside lens of the auto shade is bit of a pain in arse. Also last but not least the weight of this thing is not good, it is a very heavy helmet to be having hanging off the front of your head all day, be prepared for a stiff neck and shoulders. personally, if i knew how much i was going to have to modify before i could use it i dont think i would have spent 600 on a welding hood.
