The Smarter Tools ST-1S auto-darkening welding helmet is designed to protect the eyes and face from specks, spatter and harmful radiation under normal welding conditions. The Auto-darkening filter automatically changes from a light state to a dark state in only 1/25000S when an arc is struck and it returns to the light state when welding stops. The and adjustable sensitivity and response time makes this helmet the smart choice among other welding helmets.

Rated 4.2 out of 5 by 32 reviewers.
Rated 5.0 out of 5.0 by Good Helmet For A Good Price For The Price You Can't Beat It. It Provides On It's Lowest Setting All The Protection I Need For Welding Jobs While Being Lightweight And Comfortable. It's Adjustable Enough For Any Head And You Can See What Your Doing When Your Using It. The Best Part Is It's Hands Free. February 28, 2013
Rated 5.0 out of 5.0 by It is exactly what we needed. Using the internet to locate and order the product was quick and effective. Shipping was a snap May 19, 2015
Rated 5.0 out of 5.0 by Good self-darkening helmet. I have used this product for about two hours now and find it to perform as advertised. The head clamp works well, light sensitivity adjustment works well so to all those who were not happy with their selection either exchange it or return it to your nearest store. Quit belly-aching, you have options. January 6, 2015
Rated 5.0 out of 5.0 by A good buy for the money This is my first auto darkening shield and I am very satisfied with it. It was shipped quicker than I expected. November 6, 2013
Rated 5.0 out of 5.0 by Works really well!! Looked around a lot to compare and the closest thing with these features would have cost twice as much. No batteries to change is awesome. Solar powered right out of the box! The speed it darkens and to be able to adjust how much it darkens to, is great! Perhaps the head band could be more comfortable, but for a weekend warrior like me, it is fantastic! Only get the time to weld a few hours at a shot, so I haven't tried to wear it steadily for 4 or 5 hours straight. I can see through it clear enough to get my arc going and then the adjustable darkness lets me still see enough to run my beads once it changes. I am quite happy with it! July 25, 2012
Rated 5.0 out of 5.0 by A+ Rating Why spend $400 for a fancy paint job when this helmet performs just as well. Completely satisfied!!! August 21, 2013
Rated 4.0 out of 5.0 by cant beat it for the price i dont have to weld everyday so this works for me. auto dark helps ,no more flipping up and down the helmet. January 10, 2012
Rated 4.0 out of 5.0 by Works as promised Self darkening shield makes learning to weld much easier. I think it will have to be treated carefully. Not the most robust design. Time will tell how long it lasts. February 13, 2014
