A computerized welding control system which is capable of controlling a large number of welding heads from a single processor, the processor being the timing instrumentality for the various portions of the welding cycle. The system also includes standard welding circuitry to control the percent heat and the control of the first electrical cycle of the welding cycle. The system includes a data entry terminal for a set of welders within the group controlled by a single processor, the terminal being capable of addressing the computer to determine the time stored therein for various functions within the welding cycle for a particular machine within the group controlled by the terminal unit. The terminal unit also includes capability of changing the times associated with each portion of the welding cycle. The system also includes an automation portion which is capable of sensing various functions within an automated line and feeding data relative to the machines on the automated line to the computer and the computer will utilize this data to generate control functions for both the automation and welding portions of the system.
In a welding control system including a general purpose computer having computer cycles and programmed, to provide timing signals for the various portions of a welding sequence, and a hardware control system for the welder, the improvement comprising circuit means for enabling the hardware controller in response to a signal generated by the computer, said computer having an output data buss, said enabling signal being generated at least once for each computer cycle during the operation of said computer and said control system.
