【発明の名称】アークガス溶接または切断用トーチの動作制御装置

Document Type and Number:

Japanese Patent JPH0722829

Kind Code:

B2

Abstract:

The arc is struck by the initial short circuit between the electrode (2), the nozzle (3) and the work piece (7) by the excitation by a very low voltage source (31) of a relay (48) causing (between 43 and 42) the closure of the main contact (15), after which the relay (48) is maintained in its state by the welding or cutting current generating a voltage at the terminals of the inductance (23). Application in the control of a torch which is ignited by a short circuit between the electrode, nozzle and the torch.
