Abstract
The invention describes a control device for a welding device (1), consisting of a digital control device (4), in particular a microprocessor control, and a welding process control unit, comprising a signal processing unit, hereinafter referred to as SP unit, and a pulse width modulator, hereinafter referred to as PWM, and at least one external component, such as a power component (3) or an input and/or output device (22), etc., for example. The welding process control is digitally operated by the welding process control unit and the configuration and parameter settings for the welding process control unit are handled by the control device (4) through software means.
Claims18
A welding device comprising a central digital control unit which comprises a central microprocessor control and a welding process control unit connected by a data/address bus to form a common assembly for controlling several types of external welding process components, and the central digital control unit having several interfaces connecting the external components thereto,
- (a) the welding process control unit comprising
- (1) internal components of a signal processing unit and a pulse width modulator, and
- (b) the central microprocessor control including a memory device storing software digitally controlling the configuration and parameter settings of the external components connected by the interfaces to the central digital control unit, whereby data exchange between the external components and the central digital control unit and between the internal components is effected by digital signals so that the welding process is digitally controlled, and data transfer from the microprocessor control to the components is effected by digital data sets by a data protocol.
