SI-WELD Bidirectional 100A Thyristor Spot Welding Machine Panel Controller with SCM Time and Current Digital Display

SI-WELD Bidirectional 100A Thyristor Spot Welding Machine Panel Controller with SCM Time and Current Digital Display.

Features:

1: STM8 industrial microcontroller to process the main control core.
2: strong and weak through the optocoupler isolation, the operation more secure.
3: power cord and foot switch line with screw-free quick connect terminal, more convenient and reliable.
4: input time, current using high-precision single-bit potentiometer, to ensure reliable and convenient input.
5: Onboard power, status, foot, trigger indicator, working status is clearly visible.
6: design a reliable zero-crossing detection circuit to ensure that the SCR phase shift accurate.
7: The controller is compatible with 40A-100A thyristor.
8: a digital control interface, you can display the current set time and current.
9: time input 1-50, unit cycle (1 cycle is 20ms), current input (30-99%)
