For most jobs, eye protection that conforms to ANSI Z87. 1 is sufficient. However, shields or goggles with shade ratings of 3-8 should be worn for gas welding. For arc welding, safety glasses should be worn under shields.
Do you need eye protection for arc welding?
Electromagnetic energy given off by an arc or flame can injure workers’ eyes and is commonly referred to as radiant energy or light radiation. For protec- tion from radiant energy, workers must use per- sonal protective equipment, such as safety glasses, goggles, welding helmets, or welding face shields.
What welding helmet lens number is the minimum recommended for carbon arc welding?
As a general guideline, torch brazing and soldering should look at a minimum shade 3, SMAW/Stick welding should be 8-12 depending on the amperage, GMAW/MIG and GTAW/TIG should be minimum 8-10, carbon arc welding should be minimum 14.
What shade is safe for welding?
Both ANSI and AWS are more cautious, recommending a shade number 11 for welding at 60-160 amps, a number 12 for 160-250 amps, and a number 14 for 250-500 amps. Verify that both the welding helmet and lens shade meet ANSI Z87.

What is the darkest welding shade?
Shade number 13 is often the darkest shade available for welding glasses that will only be used for non-industrial projects involving both light and heavy-duty welding. You can also use shade number 13 for all welding types.
What shade is best for MIG welding?
For Mild steel MIG welding: For welding with amperage between 80 to 100, you should use lens shade 10. For welding with amperage between 100 to 175, you should use lens shade 11. For welding with amperage between 175 to 300, you should use lens shade 12.
Are pit vipers safe to weld in?
Diving into the tech-specs of Pit Vipers is extensive, as they have been developed to work seamlessly in nearly every situation imaginable, including but not limited to: childbirth, farming, skiing, ski touring, mountain biking, sheep shearing, partying, welding, fly fishing, visiting relatives you don’t see very often …
Does welding affect your eyes?
Visible light from welding processes is very bright and can overwhelm the ability of the iris of the eye to close sufficiently and rapidly enough to limit the brightness of the light reaching the retina. The result is that the light is temporarily blinding and fatiguing to the eye.
Do welding glasses block UV?
While some forms of welding and cutting are being done, a degree of eye protection is provided by welding goggles. UV blocking protective eyewear with side shields or welding goggles are considered primary protection, with the face shield or welding helmet considered secondary protection.
Are welding glasses safe for Eclipse?
According to the NASA total eclipse website and the National Park Service FAQ, a shade 14 welding lens is the only lens adequate for viewing the eclipse. … A lens with lesser shading will not be adequate to protect the eyes.
