description The utility model belongs to an electric arc welding device, particularly a pair of electric welding tongs without burning hands using alternating current and direct current. The electric welding tongs comprise handgrips and tong mouths. The utility model is characterized in that a heat radiating hole 3 is respectively arranged on a tong mouth sheath 1, a handgrip head 2 and a handgrip sheath at the connecting position of the tong mouths, the surface of an inner sleeve 4 of the handgrip or the inner surface of an outer sheath 5 of the handgrip is provided with bearing ribs, and a ventilating hole 6 is also arranged on the handgrip sheath. The electric welding tongs of the utility model have the advantages of large working ranges, without burning hands, high work efficiency, simple structure of the self of the device and portability and serviceability, and labour conditions are improved.
