What should I do if there is no high frequency power supply in the wire cutting machine?
First, the logic conditions of the high-frequency power supply should be explicitly turned on: 1. The medium thread cutting machine enters effective program operation; Silicone Fluid,Waterproof Silicone Fluid,Colorless Methyl Hydrogen Silicone Fluid,Nontoxic Silicone Fluid Zhejiang Sucon Silicone Co.,Ltd. , https://www.hycsilicone.com
2. High-frequency power is on standby;
3, the wire is at normal speed;
4, not in the commutation moment;
5. Use "Self-switch" to force high frequency. These five conditions can be tested separately.
If even the “self-check†switch cannot open the high frequency, you should doubt whether the main vibration circuit has pulse output, whether the high-frequency switch relay is effective, and whether the control cabinet goes to the wire feeding machine to the bed surface and whether the transmission channel is unblocked or not. Whether the rectifier bridge is broken or not, is the insurance intact?
If the "self-checking" switch can be turned on, you should check one by one:
1. Whether the SBC operation is valid or not, it can be verified by “manual frequency conversionâ€.
2. Whether the high-frequency power is forcibly shut down by the single board machine, and the operation “standby, block, D†on the panel should be able to make the “high frequency†display light on the panel bright and dark.
3, whether there is still high-frequency switch relay action.
If the observation is not fine, often make another mistake, that is, the high frequency of the WEDM machine has been short-circuited or the pulse amplifier has not been opened all the way, but because there is no spark discharge or the frequency conversion circuit does not go, there is no high frequency. This is also to pay attention.
