Bob---There may be an auto darkening helmet out there that lets you see the
work before striking the arc, but the ones I've seen advertised have only four
layers of light change admittance. Usually 9 to 13. It would seem that the
first level of #9 would still be too dark, at least for these old eyes. I have
found that training a bright light on the work to be done allows me to see
where I want to make initial contact on the work oiece. After that, I just
puddle on!

Subject: [6pack] Welding Helmet Question
One of my many problems with welding is I can't see anything until the
sparks start flying at which point I figure I'll set the house on fire
so......I'm considering one of the auto-darkening type helmets figuring I'll
be able to see where everything is before I light things up. A search of
Sears & Home Depot shows the auto-darkening models to be in the $100 - $200
range. Harbor Freight had one at $80 and eBay has a bunch of new ones listed
at $30 - $50. And I've also seen some for $400. From a spec standpoint, they
are all similar with regard to reaction time, darkness scale and meeting
various industry standards. So I'm guessing the difference lies in various
construction aspects of the helmet itself. This is something I'll use maybe
once or twice a year and my primary concern is eye protection. Will the less
expensive ones do the job given that they all say 1/25,000 sec switch time,
adjustable shade control & ANSI certified.
I remember driving down the highway a year or so ago and seeing something
blow out of the back of truck. It was a welding helmet. So I caught the guy,
who was a welding contractor, and motioned that his helmet fell out. He knew
immediately what I was motioning about and was able to turn around to get
it. If I wasn't so honest I bet I could have scored one expensive helmet!
Thanks
