    Abstract: A welding device (1) for making and hermetically sealing at least one package (P) containing a product (A), comprises a first and a second sealing and cutting equipment (2, 3). Each sealing equipment is configured to receive a respective film (F) forming a tubular envelope (F2), to seal it and cut it transversally for making at least one package (P). The welding device (1) comprises a support body (4), bearing the first and the second sealing and cutting equipment (2, 3), which is connectable to a packaging machine (100), preferably to a rotary drum (105) of a packaging machine (100). In particular, each sealing and cutting equipment (2, 3) comprises an arm (5) operating as a sealing and cutting head and an abutment body (6). Furthermore, the arm (5) is rotatably constrained to the support body (4) and reversibly movable between a plurality of positions comprised between an active position, wherein it is substantially in abutment on the abutment body (6), and an inactive position, wherein it is raised with respect to the abutment body (6). Furthermore, a locking means (20) is provided, adapted to lock the arms (5) in the active position in the welding step.
