What is wrong with the welding picture?
UV from tig is much worse than from stick, if my own experience is any
indication -- don't know about mig.
And which is proly correck -- cuz the lens for tig is considerably darker
than for stick, as well, proly for the UV. Sumpn newbies should keep in
I got burned so bad from tig -- in a tig CLASS no less -- I coulda proly
sued the school. Dat burn (hands, arms) lasted for WEEKS, very very
However, the rest of me is deteriorating "on schedule", so any ill-effects
from that burn will proly just blend in.... LOL
As far as UV radiation is concerned, amp for amp, MIG has the highest
output since there is no smoke to block any of the arc. Stick is
second, and is about the same as Dual-shield or Inner-shield wire.
TIG has the lowest UV content, with more visible white light being
generated by the excitation of the Argon gas.
TIG welding with Helium produces less white light, but more UV.
The problem with TIG is that you are often welding on shiny aluminum or
stainless steel, which means lots of reflected arc radiation on
unprotected areas, and often people are only wearing long sleeve
shirts, thinking they block the arc.
Try holding some shirts up to a light bulb and you will be amazed at
how much light comes through some fabrics.
I taught welding for 16 years, and dealt with many students sun-burn
and arc flash because they underestimated what UV can do.
Looks painful. The behavior should be self-correcting, though: next day, Bubba
to himself "Dayum! Guess Ah shoulda worn gloves!"

Probably nothing. You're jumping to conclusions. The picture is highly
likely to have been posed and therefore not representative of
anything. Nevertheless it wouldn't be an uncommon scene in a real
shop. The door is open so the space may be warm, with most
fabricating, including light tacking, done in the lightest clothing
and workers only suiting up for sustained work. Yeah I know the safety
weenies will scream like banshees but that won't have any affect on
reality. And I guarantee you, if some pictures of work being done at
your shop were taken at the right time, the same safety weenies would
have a field day jumping to their own conclusions. The reality is that
a lot of what's considered sensible safety practice can be considered
life threatening by those whose jobs depend on them condemning every
little thing. If you get a herd of them in your place, look out.
They'll start with the refill dates on your fire extingishers and end
with the missing safety warnings on your toilet flush handles. In
between... well, ask existential angst to explain that part.
Ah. Nothing like health advice from the sage crackpot who's been
consuming copious amounts of nicotine and soda daily even after
multiple infusions of life saving care paid for by others. Yes, you
probably wear sleeves to keep warm while sitting there typing out
stories about the huge amount of welding that you obviously don't
actually do. And for making excuses about welding you'll never get to
because there's some catshit in the way.
Iggy is intelligent. Adult education can be a good thing for welding,
but certainly not necessary. Learning how to weld is mostly
practice. Typiical adult class has one teacher and maybe 30
students. Which means in a three hour class the instructor has about
6 minutes per student. The rest of the three hours is practice,
practice, practice and could be done at home.
When i decided to learn to TIG weld, I took a votec class in the
evenings. The class had about 20 to 25 people doing stick and wanting
to get certified so they could get a job in the ship yard. There was
another 12 to 15 people learning to gas weld for hobby work. And
there were three of us learning TIG. I remember the first night the
instructor did not get to those learning TIG during the first two and
a half hours. By then we had figured out how to set up the machines
and had been welding . I expect during the entire class, I got
maybe an hour of instuction. But being over 60 the class cost me
about ten dollars , so the real advantage was using the schools argon,
rods and electricity. And knowing that I could TIG weld before buying
a TIG welder.
Regardless of what the operator is doing, he should not have skin
exposed to the light from the arc. If he is just tacking things in
place using a MIG welder, he will be older when he gets skin cancer.

How long did it take? Oh right, you guys don't need to know because
even a second would burn, just like a second in the sun burns I guess.
Even if he could know the exposure time, I doubt that a knowledgeable
doctor would be as certain as the two of you. Seriously anal. Anyway
karma's a bitch. If somewhere down the road I see you complaining that
OSHA and some of her tentacles showed up and gave you an undeserved
reaming worthy of one of Existential Angst's colorful narratives,
don't expect any sympathy.
Jennifer Beals said that she liked welding and got pretty good at it,
so she was upset and resisted when the director told her to make lots
of sparks. Flashdance was on TV recently and she both welds smoothly
and pecks at the work to make sparks.
Bruckheimer is the also director who made such a mess of history in
