The working principle of the welding machine power start thermistor SY/PTC 16P is to connect the PTC thermistor in series in the load circuit. When the circuit is in a normal working state, the current through the PTC thermistor is less than the rated current. The PTC thermistor is in a normal state with a small resistance value, which will not affect the normal operation of the protected circuit. When the circuit fails, the current greatly exceeds the rated current (twice the normal operating current), and the PTC thermistor suddenly heats up and is in a high resistance state, making the circuit in a relatively "off" state for protection purposes. After troubleshooting, the PTC thermistor automatically returns to a low impedance state, and the circuit resumes normal operation.
Features: high reliability, high-pressure resistance, fast response, small size, and long life.
