A machine for the successive welding of two header boxes in two end plates of different sized radiators, comprising:
- a frame;
- a rotating gripper supported by said frame and comprising two arms, namely a fixed arm and a mobile arm, said two arms being provided with removable plates of a length corresponding to the distance between the end plates of each radiator to be machined to constitute, by end portions thereof, bearing surfaces for said end plates;
- a pressing element, controlled in time relation with the rotation of the gripper, to exert a pressure successively on each of the header boxes by maintaining them against the corresponding end plate held by the removable plates of the gripper;
- and
- two heating units respectively placed on parallel rotating shafts and comprising burner heads connected to said shafts through sliding supports, whereby said burner heads are adjustable in position as a function of the radiator to be machined.
