How many types of lens are there in welding?
Most welding helmets actually have two lenses — a shaded lens, and a protective front lens. The shaded lens is typically made of tinted glass. This is what protects your eyes from the light and radiation coming from the weld site. The front lens protects the lens from dust and debris and is usually made of plastic.
What lens do welders use?
#2 Stick Welding
Type of Welding | Amperage | Lens Shade |
---|---|---|
Stick Welding – Mild Steel | 40 to 80 | Shade 10 |
Stick Welding – Mild Steel | 80 to 175 | Shade 11 |
Stick Welding – Mild Steel | 175 to 300 | Shade 12 |
Stick Welding – Mild Steel | 300 to 500 | Shade 13 |
What shade welding lens do I need?
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. 1 certification.
What is a gold welding lens?
Gold lenses reflect rather than absorb light. They restrict light from passing through the lens and give you a truer color palette. This coating reflects 90% of infrared radiation and reduces the heat to which the eyes are exposed.

Are all welding helmets the same?
Style of helmet There are two common styles of welding helmets, a passive and an auto-darkening variable shade. A passive helmet has a dark tinted lens, typically a shade #10. If most of your welding involves similar material using the same welding process a fixed-shade auto-darkening helmet may be the right choice.
Why are welding glasses green?
Green lenses are used to block infrared (IR) light and protect the eyes from heat. They offer good protection from nearby flash or exposure.
Is a gold welding lens better?
Gold Coated Lens This coating reflects 90% of infrared radiation and reduces the heat to which the eyes are exposed. It also reduces eye strain to a greater degree than the green lens due to the reflective surface which reverts both IR and UV spectrum radiation at a higher rate than the standard lens.
