Abstract:
1. Method of controlling a welding apparatus with a welding torch, wherein, when the arc has been ignited, a set welding process based on several different welding parameters is run and the welding apparatus is controlled by a control system, and in order to initiate an action, a parameter dependent on the arc, in particular an arc voltage an arc current is monitored, characterised in that a welding-end programme is called up by a defined movement of the welding torch in order to terminate the welding process without breaking the arc, and, in order to activate the welding-end programme, a welding parameter, in particular a welding or arc voltage or the welding current, is monitored and, when a threshold value is exceeded for the first time, a welding-end programme is activated and the latter is run if there is a rise above or fall below a threshold value again.
