I'd held off buying one up to now because I was perfectly happy using my
flip (nod) down mask. I'd tried one out, and was impressed, but didn't
fancy shelling out £150 for one.
I spotted some on ebay from a US based seller which looked pretty good,
and were going for ~£40. I bought one, it arrived today (5 working
days!!) and I'm really really happy with it. I paid £49 including
shipping. It looks very similar to the Screwfix offering.
I thought I'd share that.
For us thickos
what's a auto darkening welding mask, and how does it work.
I am presuming that it somehow switches from a see through state to a black
state when flashed by the welding torch. Right ?????
That's exactly what it does. It's an LCD (like a digital watch display).
The big advantage is that it means you don't have to [a] hold a mask to
your face or [b] flip a mask down. So you can use your hand to hold
stuff, and keep your head still.
What ever happened to the time old tradition of holding everything in
place, shutting eyes and turning head while making a squirmy face
while welding? Don't you lose out on the sun-tan using a mask?
You know what? I used to know a garage welder who protected his eyes by
squinting while MIG welding. I'm totally serious - he'd just squint and
weld away. I watched him do a whole patch on a fiesta this way. Couldn't
I bought one off Ebay from a guy in this country for around £100.00
all in. The helmet itself is original from a down under company.
Never tried welding with anything else but it works a treat.
Did try looking through the hand held face shield they supply with
welders before it went back on Ebay...
You can see what you are doing, it darkens immediately you start
welding and clears when you stop, all adjustable so you can have a
little delay after the weld etc. too.
The Screwfix one looks a bit "cheaper" construction wise but when all
said and done what price your health? :-)
Depends whether you're gas welding or electric (arc/MIG/TIG) welding.
The former is just a hot flame, which heats the metal to white heat. You
need dark goggles, otherwise the very bright metal [a] blinds you and
[b] makes it impossible to see hwta you're doing.
The latter make use of an electric arc, so make a *really* bright spark.
As well as chucking out lots of visible light, they also chuck out lots
and lots of UV. You need an even darker lens in this case, otherwise you
can't see what you're doing, and your eyes will be damaged in a very
short time. Much brighter than the sun.
I can personally vouch for that.... :-(
Only a couple of weeks ago I was stripping the ceiling of old plaster...
Meanwhile my mate is outside welding his car up. Accepting any excuse to
rest my arms from stripping I kept wandering out to see how he was doing. I
knew full well not to stare at the spark, and did my best to avoid looking
anywhere near it.
Anyway, to cut a long story short that evening I was adamant I had something
in my eyes - though to be bits of plaster from the ceiling - as they were
very painful. Closer examination revealed nothing and following a sleepless
night the pain still hadn't gone away.
The following morning my eyes looked well tired, and still felt like someone
had kicked sand in 'em. Still hadn't twigged this might be something to do
with the welding so went to the doc - I was concerned I was unable to see
whatever it was that was in there. She was quick to ask if I'd be welding...
...and subsequently diagnosed me as having welders' flash.
A regular dosing of wet tea-bags and several days of painful squinting later
I was right as rain having learnt a very painful lesson.
Might just pop over to uk.legal now to see if I can sue my mate... ;-)

According to the mig guide I got the bright light drys your eyes out
and causes at the very least intense discomfort plus your skin should
be covered to protect against the molten blobs of metal flying about
along with the UV it also creates.
Better safe than sorry.
He's probably blind (or as good as) now....
AIUI, people who use contact lenses should NOT use these 'auto darkening'
masks, there is a slight (ms) delay to the protection as the arc is made -
and thus a slight possibility of welding your contact lenses to your eye
