An integrated programmed automatic welding machine is presented. First, second, third, fourth and fifth independent pulse-actuated position control means respectively move the welding torch 1 up and down vertically, 2 right and left horizontally, and 3 horizontally forward and back and for tilting the torch 4 right and left and 5 forward and backward. There may be pulse-actuated wire feed control means for varying the rate of feed of welding wire to the torch, and pulse-actuated electrical control means for varying the weld energy factors at the torch. Programming means direct the time cycle of all of the control means, and digital pulse delivery means are connected to and controlled by the programming means and are connected to and control each control means, by sending thereto an appropriate quantity of pulses at an appropriate rate.
