APC devices to operate instruments for argon plasma coagulation are known. They comprise a HF generator to produce a coagulation current, a control device to control an amplitude of a HF voltage and to set a higher ignition voltage in response to an actuation signal and to automatically set a lower operational voltage. An output hub for connection of a (single) instrument is usually provided. To enable simultaneous working with several instruments, it is proposed to provide not only one but several instrument hubs to connect further instruments and to connect the control device to all instrument hubs and to configure it so that, on actuation of at least one actuation element and generation of at least one actuation signal, the HF voltage is interrupted for a defined duration and then the HF voltage is set to the ignition voltage and, after ignition of the plasma on all connected APC instruments, the HF voltage is set to the operational voltage.
