Using the correct shade protects your eyes from harmful ultraviolet and infrared radiation without compromising visibility.

Here’s a breakdown of common welding processes and their typical shade requirements:

1. Shielded Metal Arc Welding (SMAW): Shades range from 7 for amps under 60 to 11 for amps up to 550.
2. Gas Metal Arc Welding (GMAW/MIG): Use shade 7 below 60 amps, shade 10 for 60–250 amps, and shade 12 above 250 amps.
3. Tungsten Inert Gas Welding (GTAW/TIG): Shades 8 for under 150 amps and 10 for 150–500 amps.

Matching these shade levels guarantees peak eye protection tailored to your welding conditions. It is also important to consider ambient lighting when selecting the appropriate shade to ensure both safety and visibility.

How to Match Shade Numbers to Welding Amps and Processes?

To match shade numbers accurately to welding amps and processes, you need to understand the specific light intensity and radiation levels each method produces at given amperages.

For example, SMAW below 60 amps requires shade 7, while 160–250 amps calls for shade 10.

MIG welding under 60 amps fits shade 7, but between 60 and 250 amps, shade 10 is necessary.

TIG welding demands shade 8 for amperages under 150, increasing to shade 10 up to 500 amps.

Plasma cutting at low amps (below 20) uses shade 4, escalating to shade 10 for 100–400 amps.

Always consult ANSI Z87.1-compliant charts to ensure your helmet’s shade number corresponds correctly to your welding process and amperage.
