Leather welding gloves protect workers from intense heat, sparks, molten metal, and electrical shocks during welding processes. Selecting the right leather material depends entirely on the specific welding method you use. Heavy-duty applications like Stick and MIG welding require thick, insulated split cowhide or elkskin to block high radiant heat. Precision work like TIG welding requires thin, supple leathers like goatskin or sheepskin to preserve finger dexterity for feeding filler rods.
