Process and device for short circuit arc welding

PROCEDURE AND DEVICE FOR SHELF VOLTAIC ARC WELDS, IN WHICH A WELDING WIRE CONTINUOUSLY ARRIVES ALTERNATIVELY IN A VOLTAIC ARC PHASE AND IN A SHORT CIRCUIT PHASE, WHEN DURING THE VOLTAIC ARC PHASE, THE WIRE IS DISTANCED FROM THE WELDING BATH OF THE WORK PIECE AND DURING THE SHORT PHASE THE FOUNDED METAL PLAYS AT THE END OF THE FOUNDED WIRE THE BATH OF FOUNDED METAL AND FINALLY COLLECTED ABOUT THE WORK PIECE BY THE ACTION OF THE TIE THAT STARTS THE FOUNDED METAL OF THE WIRE. THE IMPROVEMENT IS THAT A CURRENT COMMAND CIRCUIT (22) IS PROVIDED WITH HIGH INDUCTIVITY THAT CONTINUOUSLY DRIVES A BASIC CURRENT OF SMALL FORCE THAT SUPPORTS THE ARC BETWEEN THE WELDING WIRE AND WORK PIECE, AND THAT IT IS A CIRCUIT OF CONTROL OF CURRENT (24) THAT GOVERN THE FLOW OF CURRENT DURING THE PHASE OF VOLTAIC ARCH OF THE PROCESS OF FOUNDRY. THIS SECOND CURRENT COMMAND CIRCUIT (24) SHOWS TIME DELAY MEANS THAT ALLOW TO TAKE A VOLTAIC ARC AREA AT THE BEGINNING OF THE VOLTAIC ARC PHASE, WHICH IS DETERMINED IN THE FIRST LINE OF THE BASIC CURRENT FOR A PRESELECTED TIME, DURING WHICH THE FOUNDED METAL IS CARRIED OUT AT THE POINT OF THE WELDING WIRE AND IN THE FOUNDRY BATH OF METAL BY SURFACE TENSION AGAINST THE WIRE AND / OR IN THE FOUNDRY BATH, THROUGH WHAT IS PRESSED BELOW AND PREVIOUS MEANS THAT ALLOW A HIGH CURRENT JUMP THROUGH THE VOLTAGE ARCH BETWEEN THE WIRE AND THE WELDING BATH WITH AN ENERGY PREVIOUSLY SELECTED TO FOUND A RELATIVELY CONSTANT VOLUME TO THE METAL DISTANCE OF THE FOUNDRY BATH. THIS HIGH ENERGY IMPULSE HAS A PLACE IN THE PROXIMITY OF THE BEGINNING OF THE VOLTAIC ARC PHASE AND FINISHES IN GENERAL IN FRONT OF THE MIDDLE POINT OF THE VOLTAGE ARC PHASE, SO THAT THE SOUL FELLOWS FIRST AND FOLLOWS ON THE BATHROOM METAL, AFTER THE BATH IS PRESSED DOWN OR STAY IN REST.
