THE NEW WELDING MACHINE SAVES TIME AND EFFORTS AS IT IS CONTROLLED BY MOVING ONLY ONE FINGER, DURING WELDING, WITHOUT STOPPING WELDING, WITHOUT GOING TO THE MACHINE. THE WELDING CURRENT IS LOWERED IN THIS MACHINE BY CONTROLLING THE DEDUCTIVE RESISTANCE, WITHOUT ANY MECHANICAL MOVEMENT. THIS LENGTHENS ITS WORKING AGE AND PRODUCES NO NOISE SOUNDS DURING WELDING
