ABSTRACT:
In a compact tool for automatic MAG spot welding, all of the elements are located close to the welding zone and a single set of props both support the articles to be welded and provide a negative electrical current contact. A welding head is slidably supported upon a base which is connected to a robot arm by quick release couplings. The base further supports a welding wire reel and brake while the head supports the torch and a welding wire drive device. Props on either side of the welding zone press the article to be welded and provide negative electrical current contact.
