Abstract: A battery-powered electronic resistance welding machine for sheet metal repair, comprising a machine unit (10), which includes a handle (12) and an activation and deactivation button (13), at least one first rod (14), which is constrained in a sliding fashion (F) to a terminal (15) of the machine unit (10), which has, at one free end, a ground electrode or tip (16) that comes into contact with at least one metal portion to create an electrical resistance circuit, at least one second rod (17), constrained in a sliding fashion (F) to the terminal (15), which has, at one free end, a welding or terminal electrode or tip (18) for the fixing of repair accessories of the metal portion. There is a rechargeable battery (11) in the machine unit (10), for example a lithium-polymer accumulator, which allows the electronic resistance welding machine to be powered without using the mains power supply.
