<P>PROBLEM TO BE SOLVED: To provide multi-spot welding equipment capable of changing the number of welded spots for each welded part. Ž<P>SOLUTION: The multi-spot welding equipment subjects works W to series spot welding or indirect welding by a pressurization gun unit 1 constituted by providing two sets of pressurization guns mounted with welding guns 8, 9 and 10, 11. There are provided two voltage transformers 33, 34 for discretely feeding electricity to the welding guns 8, 9 and 10, 11 respectively mounted on two sets of the pressurization guns. A switch consisting of a moving contact 21 and a fixed contact 22 is disposed between the pressurization guns mounted with each one of the electrodes 5, 7 among the respective sets of the pressurization guns.
