Welding problems with vision
I am a fair welder, but the problem I have most, is not technique, but in being able to see what I am doing. I use a MIG welder and a #10 base shade self-darkening lens. I also usually shine two 500 watt halogen lights on the area I am working. The problem seems to be that the exact area of the weld is too bright to see anything clearly and the area outside of that is too dark to see clearly. Any suggestions for things to try to diagnose and correct the problem? thanks, dion -- Dion Hollenbeck Email: Home Page: http://www.woodsprite.com Brewing Page: http://hbd.org/hollen |

My wife was raised in Cortez and I've visited there several times. I've even driven down McElmo Canyon for a short distance. The pictures and places were fun to hear of again. I'll be spending a week or so in Creede this August. Looking forward to escaping the heat. Good luck with your welding and your homestead. Gary Brady Austin, TX |

Could the lights be making the situation worse? Your eyes would adjust to
the bright lights when not welding and make it more difficult to see with the hood down. "Dion Hollenbeck" wrote in message ...

Sometimes I can see more if I weld in direct sunlight, which is much
brighter than a halogen bulb, I believe. I guess one would need an incident light meter (pro photographer instrument) to be sure. The problem with bright light, in my experience, is that I tend to get glare on my lens. If you could have a setup where the work was in direct sunlight, but your head and helmet were in the shade, that might be a slight improvement. But really, I never figure to see anything more than one inch from the arc, and don't really need to. One problem for those of us old enough to use bifocals is that the bifocals are set low, so if you use a standard helmet with a small window you cannot use the reading side of the bifocals for welding, you look at the weld (close) with the distance lens, which works poorly. I have a helmet with an oversized vision area, and always take it with me, since I usually cannot see anything out of borrowed helmets.

Any suggestions for things to try to diagnose and correct the problem? thanks, dion I'm using a mig wire welder and having much the same problem as Dion. I find that if I position the handle just right I can make most of the arc disappear under the gas nozzle, and that helps, but it's hard to maintain the position. With regard to the bifocals problem mentioned by Richard: I was recently given some magnifying lenses which fit inside the helmet. The ones I have are in standard bifocal values of 1.25, 1.5, 1.75 and 2.0 magnification levels. These help quite a bit as it allows me to dispense with my glasses entirely when I have the helmet on(my distance vision is still fairly good). The ones I have are not a perfect fit in the helmet but a couple small pieces of duct tape hold them in well enough. If anyone's interested I'll see if I can get the manufacturer info off the packaging to help in locating a sales point. |

I can't speak for the auto-lenses but a modern gold lens in any shade will block virtually 100% of the offensive light, you just chose a shade to suit what pleases you. This may be an option.. Mig welding produces considerable smoke which will condense on your cover lens, it doesn't take much accumulation of this to produce exactly what you're describing. Don't hesitate to change cover lenses regularly. Don't bother watching the arc, it won't tell you much. Watch the puddle and just ahead of it, ignoce the arc. John |

Make sure that the cover glasses, filter and any diopter correction are
CLEAN. This will sneak up on you. Every air-glass interface reflects light and, if dirty, scatters light. I wear tri-focals, and they are a REAL problem, because you have to look at the weld at a certain angle to be able to focus. I now keep a pair of dime-store reading glasses in my pocket, and switch to they before putting the helmet on (when I remember.) Also, treat your helmet with respect. Put it in a box, out of the way when you're going to grind, so you don't scratch the cover glasses, or accumulate dust on all the look-through surfaces. Position your work in relation to the light, or your light in relation to the work so you can clearly see the path you are about to weld. It helps if the side of a freshly ground V-groove is reflecting bright light toward you |

Any suggestions for things to try to diagnose and correct the problem? thanks, dion I found when I started that too light a lens caused my eyes to wash out a bit, making it harder to see anything around my weld. So, somewhat counterintuitively, a darker lens made the "not weld" parts easier to see. I began with a #10 and went to a #11. Might be worth it to borrow someone's #11 lens and try that. Or, if you helmet is settable, turn it up and try using it for a while. I've developed a pretty strong dislike of the auto-darkening hoods as I tend to get a headache after using them for 20 minutes. Perhaps yours is also causing you a bit of eyestrain, which can make it difficult to see. -- B.B. --I am not a goat! thegoat4 at airmail dot net http://web2.airmail.net/thegoat4/ |

I too wear bifocals. I bought a magnifying lense at the welding supply
that goes in behind the filter. With it I can look thru the top part of my glasses while I am welding.. Dan |

I have not done this, but keep planning on doing it. And that is to
paint or put tape on my welding hood so it reflects light from the arc back to the area around the weld puddle. I think this is one of the reasons a gold filter works better than the dark green filters. It reflects light back . Kind of like those mirrors with the hole in them that doctors use when looking in your mouth or ear. Dan |

Been following this thread as it applies to me. I mostly do 4130 airframe
welding with TIG. I have been experiencing a decline in both near and far vision as a function of aging. It really stinks. But to compensate I had my opthalmologist make me a pair of "welding glasses" They are bifocals with the line. The lower lens is for in close low amperage TIG work and the upper is set up for close to arms length. I use an autodarkening hood with the larger window and get by very well with this set up. The idea of a drape over the back of the hood is a good one as now that I am aware of it I can see the reflections. I held my hand back of my head an it made a real improvement in the contrast. The glasses cost me a little over a $100 because I used a frame from an old pair of glasses that was still in good shape. I do have to change glasses once I come out from under the hood. -- John "Ebby" Ebensperger Hatz Classic s/n37 Camden, NY |

"Ebby" ( clip) The glasses cost me a little over a $100 because I used a frame from an old pair of glasses that was still in good shape. ^^^^^^^^^^^^^^ That's about what I paid. And then I misplaced them. Now I use cheap reading glasses, and they work almost as well (despite my astigmatism.) |

For most work, I can use my prescription distance glasses, sometimes with a magnifier hood, and it works out OK. The optical outfit I bought my bifocals from had a fitter that asked where I wanted the closeup portion of the lens located, they didn't just stick it where they thought it would be best. The location I picked turned out to be pretty good for really closeup work and also working on computers where I have to look up frequently. I also picked the largest lens opening and heaviest frames they had, I've had too many disintegrate with bumps and knocks. Not fashionable, but with a hood or googles on, who cares? So I have to haul one additional pair of glasses around for the close work, but I'd have to have readers anyway with contacts(which I also use, sometimes, just not in the shop). Stan |
