The power line is ensured to be well contacted with the welding tongs.
The utility model has the advantages that: when the welding rod is installed, the insulating roller is only needed to be pulled by hands, so that the front end of the ejector rod is tightly propped against the welding rod, and when the welding rod is replaced, the insulating roller is pulled by fingers in the opposite direction, so that the ejector rod moves backwards. Can be replaced by small force, and is very convenient. The problem of poor contact between the upper and lower jaws and the welding electrode due to insufficient spring force caused by repeated pressing is avoided.
