Was done many years ago - sort of worked - sort of didn't. Didn't work with infra red flash but I guess they could be modified.

don't know about this
,I will not buy a cheap motorbike helmet to protect my head,why a cheap welding helmet to protect my eyes.
Just to be safe I always wear UV safety glasses under the helmet.
If the arc strikes and it doesnt darken you are in big trouble otherwise!
Do you only speed after dark? :wasntme:Quote:

i Have no problem buying anything that is made to our safety requirements at any price .
Hell when i buy a m/bike helmet i dont look at price i make sure it is to ADR and OUR safety standards then the fit comfort . The high end stuff ($$$)will have less wind noise and some bells and whistles:p
:BigThumb:
I got a message thru Ebay saying customs returned my welding helmet and did I still want it or a refund.
Told them I still want it.

Some good points made about the aussie standards.And if it has the sticker on it one would presume\hope that it is safe for use.On googling the only thing i found to be wary of is the time the helmet takes to go from clear to dark varies between helmets,Don't think it will make a difference to the very casual welder[me]but perhaps something to consider if welding constantly. :D
Miller - Selecting the Right Welding Helmet For You
Lens reaction time indicates how quickly the lens will switch from its natural light state (usually shade #3 or #4) to the darkened shade when welding begins. The quicker a welder' s eyes are shaded from the high-intensity light, the better. Entry-level lenses are often rated at 1/3,600 of a second, while industrial or professional grade helmets can be rated as high as 1/20,000 of a second. The more arcs you start in a day, the more you'll appreciate the quicker speed. If you spend all day welding with a lens rated at 1/3,600, the cumulative effect of the increased exposure to the arc light may lead to eye fatigue at the end of the day. With faster switching speeds, these effects are reduced.
