One of the no-load automatic stop circuits of DC arc welding machines
Source: InternetPublisher:toothache Keywords: Arc welding machine BSP Updated: 2021/10/14
The no-load loss of a DC arc welding machine is much greater than that of an AC arc welding machine, so it is more necessary to consider installing a no-load automatic stop device.
(1) The circuit of one of the no-load self-stop circuits of the DC arc welding machine
is as shown in the figure. The contactor KMi chooses CJ20-100A, 380V, the KMz chooses CJ20-40A,
380V, and the time relay KT chooses JS7-1A, 380V, 0.4- 60s.
