Abstract: Various embodiments are generally directed to techniques for implementing universal commands in a welding or cutting system. Techniques described herein may include a method including receiving, by a processor of a welding system, a command over a communication interface of the welding system. The command may be parsed into a command identifier. The command may be registered with a control module. The registered command may be assigned a sequence number. The command may be executed by the processor based upon the assigned sequence number. The results of the execution of the command may be stored into an output buffer. The results of the command may be sent via the communication interface to a node of the welding system.

Abstract: Dynamic power limitation functionality described herein can be used to continuously calculate a maximum allowed power dissipation for a welding power supply. The maximum allowed power dissipation can be less than a maximum possible power dissipation. The calculated maximum allowed power dissipation can then be used as a dynamic boundary condition for a welding process functionality. The maximum allowed power dissipation can be determined based on temperature so as to enable higher output currents when the power supply operates at lower ends of a temperature scale. Information provided from an output inverter and an input power factor correction (PFC) module can provide inputs for calculating the maximum allowed power dissipation. Information provided by the inverter and the PFC module can include both static design parameters and dynamic sensor information.
