Might be time to replace that helmet with something that works better.
Shrug.
Optrel makes Great helmets..but they are a bit..dear....

Mine was a gift from a pro welder whom I did some favors for. Gods but
I love it!!
Now that Harbor Freight helmet..the blue one..is a very nice helmet and
only $50..about $35 when they go on sale.

Yeah, being able to see makes all the difference in welding. You've got to
find a helmet that works for you, along with the correct glasses or
magnifying lenses if you have any vision problems. Every time I see
someone having problems welding, it's been because they couldn't see well
enough.
The higher end electronic helmets have darkness controls that normally
solve the problem of being able to see, but bright light really helps when
you can get it.
With stick welding, an important trick it took me some time to learn (I'm
slow at times) is to lift your rod to create a longer arc for a moment to
light up your path so you can make sure you know where you are going - then
lower it back into the weld and continue. When deep down in a grove, it
can be very hard to see where you are and for out of position welds, it's
all too easy to become disoriented and loose track of what direction you
are supposed to be heading in. There's nothing more embarrassing than
seeing you wandered an inch off the butt joint in the middle of the weld.

Nothing like being able to see when you're welding or diving.

I have to wear my reading glasses under my helmet, I never liked the lens
size magnifiers. When I can focus sharply, it's as good as using a lighter
shad lens.
I get my eyes checked every so often and ask the doc to write me a prescription
for what is essentially reading glasses (all I need for correction) but with a
focal length of 18" instead of 12". Then I order glasses using this prescription
from optical4less.com where they are CHEAP. I wear these for general shop work
and especially for welding. I also order some regular readers at the same time.
They cost about the same as from the drugstore but are well made. I've done this
twice now over about 3 years, still have all 4 pairs of glasses, all in good shape.

That's a good idea Grant, I do essentially the same thing. I have had good
luck buying cheap three packs of reading glasses at Sam's for $19.95. Over
the years I have gone from 1.25 to 1.5 and now 1.75. I have found using
first my old 1.25s, and now my old 1.5s work good for my computer, shop and
welding. Right now I also keep a few 2.0s around for grinding tool bits,
reading really fine print on small bearings, and other really close work.
I learned that years ago. Its awesome isn't it. I also found that if you
put three or four of those dual head 500 watt halogen flood lamps on your
work piece you can do the work at night or indoors just as easily back when
I just had a cheap dark non-automatic hood.
Not sure what the issue was with your electronic helmet. Both of mine are
Harbor Freight hoods, and there are darkness ranges recommended based on the
type of welding you do. The only difference in performance between the
cheaper one and the more expensive one is the flimsyness of the "feel."
Well, the more expensive one has easily replaceable batteries, and goes
clear slower. I noticed I can weld better if I set the hood in the range
for the technique I am using rather than just setting it to max dark like my
old standard hood.

I donno. I think I just am not that good. LOL.

You betcha. When sunlight is not available halogen flood lamps help a lot.

Its not 100%, but I have a trick that helps. I get all lined up for my
weld, envision it going perfectly, and then I make a few non-powered
practice passes while envisioning the weld going perfectly. You can't do it
exactly with stick, but you get the idea. Then when I make the actual weld
I just pull away and stop if it doesn't feel good like the practice pass.
I'm sure that would just slow down a good professional welder, but it works
pretty good for this slag monkey. Funny though, it was a commercial
construction welder that taught me that trick. I watched him make dozens of
welds with no hood by turning away and not looking in that direction while
he welded. When I asked him about it he told me that trick often saved him
time for single welds on a job site. I'm sure the safety Nazis would throw
a fit, but it worked for him. I never tried welding like that without a
hood, but the practice pass has helped me a lot, especially in the last
couple years as I have actually started learning how to weld. It has REALLY
help as I have been teaching myself to MIG weld aluminum.

Another trick I use sometimes when I'm having trouble following a hard-to-see
line is to use a straight piece of scrap material and clamp it a little ways
away from the weld but parallel to it. The arc reflects off the piece as I weld
along, plus you can see the piece so you you know where you are. When I'm
welding steel tube, a piece of aluminum works well. Spatter doesn't stick to it,
or not very well anyway, and a quick wipe will clear the aluminum again,
restoring its reflective property.
When I have a butt joint that's tightly fit and I'm MIG welding, another thing I
do sometimes is to put a tall tack right at the far end of the weld. Again, the
arc reflects off the tack, making it like a little homing beacon.
It certainly is embarrassing when your weld wanders, isn't it?
Grant
Wandering off course embarrassing? I once welded the bearing in a caster
when I was tryig to weld the caster to a frame.
I also have filters in 9, 10, and 11, depends on what I'm doing. Tack
welding and fitup is so much easier with a lighter lens.
I have trifocals, the auto dark helmets have the view port in the wrong
spot. Unless I want to get a specialty prescription, I am stuck with a
regular helmet, large lens.
Has anyone tried putting a typical 500W halogen shop worklight nexto the
work piece?
I havent fired up my Hobart 140 yet (honeydo job list is ahead of the
welder) but was wondering if it would throw enough light to make the work
more easily visible thru the helmet window/lens
Maybe it's just me, but if I can't see the weld seam, even at night or with
room light - I have either neglected to put on my reading glasses, or by
clear lens needs to be changed. I wouldn't think under normal conditions,
seeing the weld seam should be a problem.
Also on practice passes, always try to brace at least the elbow of your
opposite hand/arm on something solid, and check to make sure you can move
your hands the length of each continuous weld without moving your elbow, or
binding the weld cable, before you drop your hood and begin welding. Comfort
and bracing is very important if you are having problems and your situation
allows it. Yes, I often weld free hand with one hand today, but I have been
doing this a long time. But even today, if I'm in a difficult position or
want most attractive bead possible, I still do these things today.
Absolutely, but I usually find the technique most helpful with my plasma,
when cutting drawn shapes. I wouldn't think it should be necessary if your
lenses were in good shape.
I know that a halogen light will trip my helmet to dark if it hits the
sensor.
However a light directly over the table works great.

This is likely the right track. without glasses I can see much better in
the sunlight than in artificial light.
If you get a bigger welder big fat rods like 7024 or even fat 7018 you
really don't have to see what you are doing the flux crumbles away as the
rod gets shorter.
Fran
I use brazing goggles or hood and at the very least glasses / goggles
If I have to do a lot of horizontal cutting I might consider a hood.
I use brazing goggle when looking at my CNC table cutting - from 6' away.

I have progressive lenses and had the same problem at first. To see close
up, I have to look out the bottom of my glasses, but there was no way to
adjust the helmet enough so I could do that. And I have a bad enough
astigmatism that using simply magnifiers alone wouldn't let me see well
enough to weld.
But them I figured out how the bifocal prescription worked and how the
optics of glasses work. If you have an astigmatism, it means you need
different strength lenses in one axis vs another. But when you get
bifocals, the only difference in the reading part of the lens, is a simply
addition of magnification. A prescription might be written as +2.00 add
for the near vision or bifocal part of the prescription. What that means,
is that to turn your distance prescription, into a reading perspiration,
you simply have to add a 2.00 diopter magnifier.
When lens strength is measured in diopters, they simply add when you
combine lenses (or close enough). If you look though a 1.00 diopter lens
and a 2.00 diopter lens at the same time, the effect is basically the same
as using a single 3.00 diopter lens.
And that's how the reading prescription works as well. If your reading
prescription is written as +2 add, then that means you can turn you
distance prescription, into your reading prescription, simply by adding a
+2.00 diopter magnifying lens to your helmet. Which is exactly what I
did. Which means I can wear my normal progressive bifocals, and look
straight out with the distance part of the glasses, but because of the
combined effect of the magnifiers, I'm effectively getting my reading
prescription that way, and can see the weld just fine.
It seems to me that this trick should work for anyone that needs glasses.
Adding a magnifier to your helmet will turn you distance prescription, into
a close up "welding" prescription, and allow you to use the distant part of
your bifocals (or trifocals) to see at a welding distance - so that you
don't have to buy a very expensive large window helmet. It certainly works
well for me.
The drawback is that you can't see far away - so if you want to walk around
and do distance work with your helmet down, or do grinding with your helmet
down, that won't work. I never do that however, I flip the helmet up for
everything except for close up welding so only being able to see well close
up when the helmet is down works fine for me.

Yes, that's exactly what I use. That and a Northern Tool helmet to
replace my no-name Chinese e-bay helmet have made a huge difference.
This is normal (universal?). Closing your pupil some increases depth
of field.
I might add that regular (old fashioned) 3 lens trifocals have some
different problems than either bifocals or progressives. I had the
optical place make the reading portion oversized, I can see an entire
computer screen without moving my head. That works great until you go
hiking on rough ground, you REALLY need to see where you are putting
your feet down!
The more expensive ones also have a larger window.
The more expensive auto dark lenses are the same viewing area as the
regular large lenses.
Ive got a Pair of 300 watt halogens mounted above my welding table..and
I run them whenever Im tigging and quite often when MIG welding.
It really really helps
