2. When welders work in welding places where electricity may be conducted, the welding gloves they use should be made of materials with insulating properties (or additional insulating layers) and can only be used after passing the 5000V voltage resistance test.
3. Material requirements for welding gloves
3.1 Appearance: The first-grade leather body is uniform in thickness, plump, soft and elastic, and the leather nap is delicate, uniform, firm, and consistent in color depth. No greasy feeling; the second-grade leather body lacks plumpness and elasticity, the leather surface nap is coarse, and the color is slightly dark.

4.1 The seams between the palm and the back of the hand of welding gloves should be inlaid with strips of leather. The strips should be made of chrome-tanned cowhide or pigskin. The edge leather and reinforced lining should be made of the same leather as the palm and the back of the hand. The width of the reinforced lining should be more than 15mm;
