The utility model puts forward a projection welder, comprising: a projection welder body; an upper electrode arm, which is arranged on the projection welder body; a fixedly-arranged lower electrode holder, which is arranged on the projection welder body and is arranged below the upper electrode arm; a manual control switch, which is arranged on the projection welder body; and a controller, which is respectively connected with the upper electrode arm and the manual control switch. When the manual control switch is pressed down, the controller controls the upper electrode arm to carry out projection welding. According to the novel projection welder provided by the utility model, projection welding can be ensured to be carried out after the finger leaves the projection welding position, so that an occurrence of a finger injury accident can be avoided and thus the security of the projection welder is improved.
