I originally had two pairs of welding gloves, both Lincoln. One pair were lightweight WIG gloves that were nothing but leather, the other were tough black gloves meant for anything else. Lightweight gloves were great for TIG, but they didn't handle the heat well and ripped easily. The heavy duty gloves seemed fine, but you lose a lot of dexterity and the leather turned out to be cheap leather that shrinks with heat. Materials. They work great! I'm a person who usually wears size S gloves and the mediums are actually too tight but they break down quickly after only a few hours of flexing. subtle movements. It has unmatched thermal protection and allows you to get really close to metal without worrying about burns. I've used them for TIG, MIG and TIG welding with all sorts of fillers and materials of various sizes and amperages and they are great for all processes. The cut resistant Kevlar is the icing on the cake of an already great glove and has already saved my skin when I slipped on a sharp piece of steel. Cut through the skin and could have easily gotten a nasty scrape on the palm, but the Kevlar lining saved the day. Unless I'm working with REALLY hot and thick material, these are the only pair of gloves I will use. Highly recommended!
