Will the autodarkening helmet/shade help me or hurt me if I'm just learning.If it helps me get better welds, it's worth it but I won't pay for it just to havesomething cool that I could do just as well without.
Reply:The auto darkening welding helmet will not hurt you. It is very helpful for TIG welding.It changes from dark to light in 3/100 thousandths or quicker.The main advantage is not having to snap the manual helmet up and down all day.You can imagine if you were snapping the helmet up and down all day for many years,This is a complicated question but in general....Use a shade #10 for ocassional welds, but if you are welding all day use a shade #11.If the day after you have been welding and your eyes feel sore, you need to move up to the next darker shade.Also all eyes are different. If you have blue eyes there is different pigment. The blue is actually the rods and cones in the back of the eyeIf you have brown eyes you have darker pigment and that is a factor. Then there is the age factor etc,etc.,.Last edited by Donald Branscom; 01-14-2009 at 04:20 PM.AWS certified welding inspectorAWS certified welder
Reply:Thanks. So I assume you mean that blue eyes are extra sensitive so I should go with the #11 I guess.
Reply:I did buy a miller helmet today and the instruction booklet say to use shade 10 for less than 50 tig amp, shade 11 for 50-100 amp, shade 12 for 100-200 amp and shade 13 for 200-400 amp
Reply:Auto darkening helmets definitely hurt my eyes less than a conventional helmet hurts my neck. Also, keep in mind that auto dark helmets protect you from 100% of UV radiation that causes eye damage even when they are not dark. As a relative novice I have only used a few helmets, but from my limited experience I can say a couple things that I consider important.Multi-sensor helmets with adjustable sensitivity work better for TIG than single sensor helmets without, and cheaper multi-sensor lenses don't work very well when condensation is an issue. Recently, I have used a $40ish HF helmet, that works well for stick welding, but fails to see the arc consistently for low amperage TIG welding, and a Northern Tool TechMan lid that works extremely well until too much of the humidity from my breath condenses inside of the lens while working in a cold garage. Some of the cheap hood are likely to work in a variety of conditions, but some of the better lenses are probably more tolerant to humid environments.
Reply:the quality of the helmet is paramount as I have a cheap princess auto one that does work well but it takes just a hair longer then a miller I have to darken when using all day I can tell cause my eyes r sore with the cheap helmet but r always fine with the good one.

Reply:If you choose an AD helmet, pay enough to get up to the adjustable shades. You'll never know what you'll need in the future. Mine is in my locker, but I think it's 9-12 (maybe 13). Four sensors are probably a good thing. I was watching someone in class, and if the weldor's arm blocked my sensors, I got flashed. Mine uses AAA batteries, available anywhere.I won't buy another one that doesn't turn itself on. Mine shuts off at 30 minutes. If I'm 31 minutes between welds, I may get flashed if I forget to turn it back on. Surprise My AD made a huge difference when I was learning.9-11-2001......We Will Never ForgetRetired desk jockey.

Reply:I just ordered the Miller Elite Digital AD... seems like it will be a good hood. |
