Can you weld with shade 5 glasses?
For light work, shade 5 is usually sufficient. However, it should not be used if your work activity involves arcs, such as MIG and TIG, because they’re not dark enough to shield your eyes from the very bright light of the arc.
Can you get welding flash through safety glasses?
The welding arc produces harmful radiation which can damage the eyes and cause the unpleasant “welders flash.” Safety glasses are a way of blocking out UV light and infrared wavelengths emitted from the welding arc.
Why are safety glasses important for welders?
How Safety Glasses Protect Your Eyes. A welding helmet protects your face from the bulk of flying materials, sparks and hot slag. A helmet alone, unfortunately, won’t always keep you safe. Helmet manufacturers recommend wearing a pair of approved safety glasses underneath your mask as an additional layer of protection.
What number shade lens is the minimum required to protect the eyes when welding?
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.
Is Shade 5 enough for welding?
What shade of welding lens should you use for MIG welding? It’s recommended that you use between a shade 10 to a shade 13 welding lens to prevent flash burn on your eyes. The higher the number the darker the shade will be.
What is the minimum shade for arc welding?
For example, shielded metal arc welding requires at least a Shade 7 and up to a Shade 14 depending on the electrode size and arc current. For gas welding and oxygen cutting operations, a Shade 3 up to a Shade 8 is required depending on plate thickness.
What shade lens should you use when cutting?
A Guide to Welding Shade Numbers
| OPERATION | ELECTRODE SIZE X/32 in. (mm) | SUGGESTED SHADE # (Comfort)1 |

| Gas tungsten arc welding | . | 14 |
| Air carbon arc cutting | ||
| (Light) | 12 | |
| (Heavy) | 14 |
Does welding ruin your eyes?
Exposure to infrared light can heat the lens of the eye and produce cataracts over the long term. 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.
Do welding glasses block UV?
Use of protective eyewear while welding helps reduce harmful effects of ultraviolet, visible, and infrared radiation.
Why do the mechanics wear glasses while they are welding?
Welders wear special goggles or face masks with glass windows to protect their eyes from electromagnetic radiations.
