Abstract

The invention relates to a method for the contactless ignition of a welding arc, in addition to a circuit (28) for the contactless ignition of an electric arc, comprising a charging circuit (31), at least one pulse capacitor (30), a decharging circuit containing a circuit, and a high tension converter (32) which is used to inject the high frequency ignition pulses discharged by the pulse capacitor (30) via the circuit to the welding electrode (27). In order to create said type of ignition method and an ignition circuit (28) which enables the welding arc to be ignited in an exact and / or safe and rapid manner and / or to create an improved ignition quality, the charge circuit (31) is connected to a pulse compression circuit (40) comprising the pulse capacitor (30), the high tension converter (32) and the circuit, the circuit being formed by a magnetic throttle valve (41), such that a high frequency circuit of the ignition pulse can be obtained.

Description

technical field [0001] The invention relates to a non-contact welding arc ignition method and a non-contact welding arc ignition circuit, in which a high-frequency ignition pulse is applied between a welding electrode and a workpiece to be processed to ionize the gap between the welding electrode and the workpiece gap, and after the welding arc is ignited, the welding current is switched on, the circuit includes a charging circuit, at least one pulse capacitor, at least one discharge circuit including a switch, and the high-frequency ignition pulse emitted from the pulse capacitor via the switch and the welding Electrode coupled high voltage transformer. Background technique [0002] The welding arc ignition method and the ignition device according to the invention are in principle suitable for a wide variety of welding processes, such as WIG (tungsten inert gas) welding processes and plasma welding processes, and for welding with consumable or non-consumable electrodes met...
