Very low power plasma arc cutting equipment |
摘要 |
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.
