At present, the welding masks in China are almost the same, but the big names like 3M, Miller, Lincoln and ESAB are very expensive, which I can't afford for an ordinary welder. Later, I found one on 1688, which was made in Wenzhou. It seems to be Essen mask, but I can't remember the specific company name. The quality is good. After two years of use, there was no hole, but the battery was changed once.
