Learning to weld with a non-aircraft project

Corky,
At the risk of sounding completely naive (I know nothing of welding)
couldn't you replace the lens/filter in the full face shield you were using
with a TM2000 lens/filter?

Ah, sorry, I did not describe the face shield properly: It's a full
plexiglass shield, not a face shield with a little window in it.

Yes, had it been the face shield with the window in it, I could have
replaced that window with the tinted glass from Tinman. But I would
have experienced the same problematic cutting off of the lower field
of view that I need for proper focusing.

Using the plexiglass face shield, you don't have to worry about
cutting off your field of vision, the entire shield is see through
tinted plastic.

Does that explain things better?

Yes, much. So theoretically you could cut a rectangular window in the
plexiglass shield (positioned appropriately for your vision issues) and insert
the tinted glass rectangle from Tinman. That way your primary field of vision
is properly protected, yet you still have some secondary field vision, too.

I have no idea if this is workable, however.

There are actually full face shields that are designed to have the
narrow window that the goggles use. These are the shields you often
see guys wearing who are doing TIG and MIG welding, as well as stick
welding. The reason for the full face protection is because there is
often a lot of spatter from the welding process when using MIG and you
definately don't want those molten droplets hitting your face.

The lense in these shields is often so dark that you literally cannot
see your work with the shield down, so you get yourself arranged with
the shield up, and configured so that it will drop down over your face
with a nod. Then you get set to weld, hold you hands where they need
to be, nod your head and begin.

Welding with Oxygen and Acetylene is different. The face shield isn't
so dark, it's more like dark glasses. You can see with it down so you
don't have to get yourself so pre-arranged before dropping the shield:
You can pull the shield down, light the torch, adjust the flame and
begin.

The lense that I got from The Tinman is a bit lighter than what I've
used in the past so this aspect makes it easier to use. It's also
configured to protect your eyes from the flares encountered while
brazing, in addition to protecting your eyes from the damaging rays
produced when welding.

When I said I could replace the lense of a full face shield, I did not
mean that I would take my full face tinted shield and cut a hole in
it. I meant that I could have bought a full face shield that had the
little window, the same size as the lense I got from Tinman, and
exchange them.

But y'know, you've got me thinking. I'll go out to the shop tonight
and have a look at the whole lense enclosure and see if it might be
possible to graft it on to the tinted face shield. That might give me
the best of both worlds. Thanks for the suggestion.

I removed the dark lense from the shield and put in the Tinman's lense.
He offers one lense that fits into this type of shield. I can flip it up
to light the torch and position the work. I flip it down for the actual
welding. It works for me but I do not do high production type welding.

The real reason for the dark and opaque face shields for TIG/MIG welding
is that any electro-arc welding generates lots of UV, which can cause
severe "sunburn" and skin cancer. Be sure to cover up when using any
electro-arc welder!

Hear!Hear!

And the sunburn hurts, too!

I bought one of these electronic units that allow you to see your work, then
darken as soon as you strike an arc.

A super investment.

Amazing how bright that 1/20000 second can be, isn't it.

My learned brother and I were discussing those hoods one day and I axed him
if that is the technology used in the military to prevent eye damage from
laser attacks. IIRC, he told me that a laser could burn out your optic nerve
before the glass wen t dark.

That laser light must be a lot faster than reg'lar light, huh?

I hope that you didn't injure your brother too much when you axed him!
