What it welds
The Lincoln Electric K3034-4 Auto-Darkening Welding Helmet is an auto-darkening.
Check that range against OSHA's minimums for your work: shade 10 for MIG from 60 to 500 amps, shade 8 for stick from 60 to 160 amps, shade 8 for TIG up to 150 amps. Shade chart.
Per the maker: viewing area 12.5 square inch; optical class 1/1/1/1. What each spec means.
Test the lens before every use; a lens that fails to darken exposes your eyes to the arc. Wear safety glasses with side shields under the helmet where chips can fly, as OSHA's fact sheet advises.
Also on the listing: a weight of 1.4 lb.
Warranty, per the listing: 5 Year Manufacturer.
