Yesterday. Newbie welder. I'm welding on a stainless tank with 3/32 309L rods. The tank is outside and the sun is at my back. I do a dry run to check my position and everything is fine. I'm using a crackerbox set at 85 amps. As soon as I strike an arc, everything changes. Now, there is more light coming in from the back of my helmet than I realized and my project just turns black. I can see the arc, but nothing else. If I pull up on the rod to illuminate, the arc goes out. I can't see where I'm going and even get disoriented and lose my balance. I'm getting slag inclusion and mud dobbers nests. Every now and then I get a couple of inches of good weld. I try shifting my body to reduce the glare inside my helmet, and even hold a piece of cardboard behind my head with one hand while welding with the other. Not much help.If the tank weren't so large, I would reorient it. I have the darkess control on my shield set to about 10. I think the max on it is about 12. How low can I turn the dial down and not cause harm to my eyes? Will this help my visibility problems?The rods felt like they were running a little cold, but they are rated to run between 60-80 amps. I had the box set to max while at 110 volts. I could change over to 220v, but would have to move everything to get closer to an outlet.
Reply:Shade 9 is what I use. And the glare can be fixed from 1$ to 75$ depending on how youbwant to approach this. Option 1. Get you a cheap bandanna from walmart tie it around the back of you hood. BAM! All sun glare and.reflection gone. Option 2. Take use in using patio umbrellas the cool your entire body and remove any sun on your back while welding. Option 3 get you a pancake. No sun glare is allowed into the hood from behind it is custom shaped to your face. Any other questions on specifics about the hood I can send pics or help. Good luck.
Reply:What he said.
Reply:I got the helmet at TSC. It's a name brand like Hobart. I think the lowest setting is an 8. Do you suppose they would make a shield that would get light enough to stop protecting the eyes? Seems like they would design safety as the overriding factor. I really like the idea of the patio umbrella. I got real hot yesterday. Sun at my back, sun reflecting off the side of the metal barn, sun reflecting off the stainless tank, welding heat, full leathers, and frustration to boot.I'll look into pancakes and getting some kind of cloth hood for my back.Thank you.
Reply:Once again. The lighter shade still filters out the damaging UV that will damage your eyes. You may see spots for a while with it turned down to 9 or some hoods even less, I have one that you can go down to 5, but you wont get arc burn.Trailblazer 302Hobart Stickmate AC/DCLincoln SP 135 TSmith torchSpoolmatic 30A

Reply:Two more suggestions -Use a soapstone to mark where you want to place the bead, or adjacent to where you want to place the bead. In either case, follow it. The soap stone will burn off and not affect the weld, but the white line will help you see where you are going. I made up a thin black leather extension with snaps to attach to the top and upper sides of my hood. It covers my head and hangs down behind my head to block the light getting in from the back. It's very hot working in there in the Summer, so I don't use it unless I have to. I made a similar front extension (bib) that snaps onto the bottom edge of my hood to protect my neck. They both stay in my helmet bag unless they are needed. They work very well, but in warm weather they can make it too hot to use all the time. Being able to quickly snap them on when needed and off when not needed makes a big difference.CharleyMiller MM252Miller Bobcat 225NTMiller DialArc HF / DIY Cooler2 Victor O/A TorchsetsMilwaukee 8" Metal SawMilwaukee Dry Cut "Chop" Saw 5 Ton Wallace Gantry Various Grinders, Benders, etc.
Reply:This time of yr I'd weld on it at night if this can be your choice. Cooler and no sunglare. Just get a bright lite so you can see when not welding.

Reply:All excellent suggestions. I was just going to use duck tape, but I like the idea of snaps. Wonder how they attach?Every time I weld something, I learn something else not to do. Didn't think about the sunshine when I positioned the tank.

Reply:Just wearing a hoodie and pulling it up over the back of the hood will block the backlighting. But just don't wear it home from the 7/11 store with Skittles and Arizona Iced Tea in your hands in South Florida. :-)Thomas

Reply:I have no data to back it up but welding with too light a shade sounds like a bad idea especially if back lighting is leading you to do it.I find great comfort in the dark.
Reply:I thought I would elaborate a bit more. I know this varies from person to person and how good/bad their eyes are but just a general standard for selecting shades Attached Images
Reply:Interesting chart. I did a little more investigation on my helmet and saw that it goes from 9-13, not 8-12 as I thought it did. It also seems that I have it turned down to 9 already. So, that seems to be a moot point. However, the backlighting has generated a lot more response than I thought it would. Evidently this is somewhat a problem for some people. Before I found the piece of cardboard that I used, I walked around the barn looking for a heavy apron or something that I could just drape over my head like the old time photographers. I didn't really relish trapping fumes though, especially since the last piece I would be putting in was a galvanized bushing (even though I took a grinder to it).Got some better ideas here. Thank you.
Reply:I have heard talk of a low battery causing the helmet to defer to darker shades even if you have it on 9 but it sounds like you are looking into the image of your own face.I find it weird that someone old enough to weld is wondering how to cope with glare. I mean when youre 5 and go to look at something and the sun is in your eyes you put your hand up to block it.
Reply:Glare has always been a problem for me especially after I started wearing glasses - around age 16. Welding on the other hand is new to me, as I said I am a newbie to this and still learning things that most welders just take for granted. It gives me more appreciation for how easy they make it look.

Reply:I took a microbiology course 2 yrs back. We did a project with bacteria in two Petri dishes. We exposed both Petri dishes to UV rays from a UV lamp. One Petri dish had a clear cover and the other was not covered. The one that was covered had normal bacteria growth, the other had very little or no bacteria growth at all.Those results were expected, because most glass and plastic products block 99% of UV rays. So... You could go as low as you want, without damage from UV rays. That doesn't mean that it is still healthy though. A lot of headaches are caused from your eyes straining like from, starring at a screen all day, squinting to focus on an object. Heck, the eye doctor said my daughter needed glasses because her bangs are in her eyes to often causing her eyes to permently adjust to focus to its environment.Last edited by toolbox; 08-25-2013 at 12:36 AM.
Reply:How old are you?You may need a cheater lens. When your natural lens (in your eye) won't adjust to seeing something close, your iris contracts. Then your pupil doesn't dialate as it should, let's less light in, and you have a hard time seeing. This is compounded by light coming in behind your helmet. If you're over 40 or you tend to be naturally farsighted, but a 1.00-1.25 diopter cheater lens for your helmet. You will be amazed at the difference. I had the same problem you are having. No problems with aluminum because the puddle is brighter. Low amps on steel or SS and I saw nothing. Adding a cheater allowed my pupils to dialate and let more light in.TA Arcmaster 300CM3XMT 304S22P12 suitcase feederX-Treme 12VSOptima pulserTA161SMaxstar 150STLHypertherm PM45OP setupStihl 020AVP, 039, 066 Magnum
Reply:I'm 54. Someone on this panel recommended a cheater lens a while back and I took their advice. I don't remember the power (1.5 - 2). It did help a lot. I think at the time I was having problems welding and looking through the bottom of my lenses (which are progressive). Then I got the cheaters and now I can look straight forward - much better.I just started to learn welding about a year ago, and as I said earlier, there is more to take into account than is apparent.
Reply:Originally Posted by Broccoli1A clear safety shield will protect you so go as low as what is comfortable for you on your hood.Seeing spots? Probably too low but only causes eye fatigue, your eyes won't fall out of your head. Interestingly enough you really can't do serious damage to your eyes wearing Nothing because your brain forces you to blink and squint and do all kinds of things to self protect the eyes.Damage occurs most often to those receiving indirect UV rays while around welding. The eyes/ brain don't perceive indirect light as such a problem but it is, that is why safety glasses or shields are recommended around welding or any other operation that produces UV light at such intensity.Not wearing a hood WILL guarantee a full on sunburn to the face though
Reply:Retinal ExposureIn addition to actinic UVR measurements, another study was published as a USAEHA report (Ref. 7) in 1977 containing an evaluation of potential retinal exposure hazards. The eye can focus an open arc onto the retina where an injury might result that was photochemical or thermal in nature. Photochemical injury is the result of exposure to intense blue light sources, whereas thermal injury can result from all visible and some near-infrared radiation, which is largely invisible. Measurements of blue light and other retinal-thermal emissions suggest momentary viewing of electric welding and cutting arcs does not exceed retinal exposure limits; however, staring at an open arc can readily exceed these standards. While staring at the arc should never be permitted, actual retinal injuries are rare (Ref. 8) and would likely result only from chronic staring.http://www.aws.org/wj/dec02/feature.htmlIf you force yourself to stare at the Arc- chronic staring- and well if you are one of those people looking to win the Darwin Award- then yes, you could do damage.But normal people don't do this so the one or two times that you flash yer self is not going to cause damage. You'll see spots but you'll soon learn to NOT flash yer self.You are in more danger of eye damage from the other activities surrounding welding: grinding and mechanical cuttingEd Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridgeOriginally Posted by Broccoli1Retinal ExposureIn addition to actinic UVR measurements, another study was published as a USAEHA report (Ref. 7) in 1977 containing an evaluation of potential retinal exposure hazards.

Reply:I'm not expert. I use 9 for most steel work. I suppose if I set my machine to a a higher power for thick stuff setting I'd probably want to use a higher shade number.Aluminum might be different, there's real welders her who might speak to that.Hey~!! It's a hobby. It's not supposed to make sense~!!
