Inside lense replacement for speedglas helmet

admin

Hey guys I'm new to the forum and have a quick question. I got a speedglas 9002v from my brother in-law. He is a professional welder, I would have never spent that kind of money on a helmet. I'm just a home car hobbyist guy. Anyways apparently he didn't run a protective lense on the inside of the helmet so now the glass itself is pitted. I was just wondering if I can actually open this baby up and replace that?  It's not like it's unusable but it would be nice to have it perfect again. I will be replacing the outside protective lense that will help a lot.   Any help is appreciated. Thanks,Greg
Reply:On mine the inner cover is replaceable.  I can't remember for sure but I don't think things will stack up right if you try to assemble with out it.  If the auto dark module it's self is damaged I am afraid you are stuck with what you have.DanManipulator Of Metal

Reply:I would not use this helmet. Contact 3m and let us know what they say.

Reply:Originally Posted by DanD78Yes mine has an inner plastic glass. I agree with Mike. Call your LWS or 3M. Dan
Reply:I don't think you're understanding what is being said here.You need to call the manufacturer.  It is NOT meant to be used without the inner protective cover.  Without it, the glass gets damaged (as you have seen).Damaged welding filters (i.e. the glass) can be quite dangerous.My guess is you have a nice piece of headgear with a garbage filter.
Reply:Hello E36alpine, I would respectfully disagree with some of what has been shared by others here. Is that lens "supposed" to be used with a protective inner plastic cover? Yes. Will it harm you to use it without one? No. However, the pitting that has already been done to it will always be there and to limit further damage, the inner plastic covers should be used from here on out unless you wish to experience further degradation of your viewing. The inner glass surface that has been damaged due to use without the inner shielding cover is not designed to be replaced, it is an integral part of the lens and it's replacement, although possible, would require much more time and money than a new one would cost. So if it is still usable, ie, you can still see through it without excessive viewing issues, simply install an inner shielding cover and go to work. Probably not what you wanted to hear, but that's the long and short of it. Good luck and regards, Allanaevald

Reply:Well then again this is from the manual hahaDo not use welding filters that are cracked, pitted or otherwise damaged as these conditions may compromise eye/face impact protection and may allow harmful UV and IR radiation to pass through causing permanent eye injury and vision loss.
Reply:Hello again E36alpine, I should have probably included just a bit more information for clarification of what "I" feel are the issues here. If you had actual cracking of the lens or areas of the lens that were differing in their shading ability or the switching function wasn't working properly, then I would say that the lens had been compromised and that it would not be safe to use. However, if the internal parts of the lens have not been affected by the pitting(this appears to be the case here), the most that you will experience is a slightly less than clear view of the welding picture. The human eye is an amazing device in it's ability to essentially disregard things other than what we are focusing on. The pitting may appear to be an annoyance when you look at before you put the hood on, yet when you go to weld with it you may very well not experience any viewing issues. Best regards, Allanaevald
Reply:The lens can visually function (darken) as normal to the user and still let unwanted items pass. As has been stated...... the auto darkening lens has spatter on it.
