The longevity of these MIG welding gloves is enhanced by the utilization of abrasion-resistant goatskin leather and the inclusion of durable keystone thumbs. Additionally, their 6" gauntlet cuffs offer increased coverage as a safeguard against potential heat hazards. The gloves are meticulously crafted using a cut-and-sewn construction technique, resulting in a snug and nimble fit. To fortify their protective properties, the gloves boast a lining composed of a blended aramid material, which endows them with comprehensive 360° ANSI Level A4 cut protection as well as ANSI Level 3 puncture resistance. Rigorous testing has bestowed upon these gloves an impressive arc flash level 3 rating and an ANSI level 3 heat rating.
