This work presents the development of a welding machine MIG/MAG (metal gas inerte/metal active gas) whose exit current is pulsed, the control was developed starting from a simplified mathematical model, what allowed the elaboration of a program of simpler digital control. The mathematical model was based on equivalent circuits of the components of the process. These equivalent circuits allowed to...
This work presents the development of a welding machine current MIG pulsed that it uses a mathematical model. Initially the control model is developed with theories and applications PID which should be adjusted in agreement with the operation points stipulated by the variation of the stick out. That process becomes disadvantageous in a real process due to you continue changes of the points of operation...
