  • Automatically controlled arc-welding device for welding tie elements to a work place
    Patent number: 4503310
    Abstract: An arc welding device for welding tie elements to a work piece includes a welding head for positioning one tie with respect to the welding spot on the work piece and exerting pressure between the tie and the work piece. A control member determines the amount of energy to be dispensed by the energy source to the welding head. A memory stores data indicating the relation between amount of energy dispensed and various welding parameters. A measuring member supplies values for some of the parameters. A measuring member compares the amount of energy actually dispensed with the energy determined by the memory member and readjusts the setting for the energy source as a result of this comparison.
