A multispot mesh welding machine has a row of welding electrode holders (2) on one side of the working plane of the mesh (Q, L), each holder (2) being electrically connectable to a selected one of at least two busbars (11, 12, 13, 14) which extend across the machine transversely of the direction of advance of the mesh (Q, L), by a respective switching member (9) movable with respect to the electrode holder (2). Each of the elctrode holders (2) has a contact tongue (6) overlying the contact faces of the busbars (11, 12, 13, 14,) and the respective switching member (9) is positioned between the contact tongue (6) and the contact faces of the busbars (11, 12, 13, 14). |
