Portable Digital Display Spots Welding Machine Control Panel Spots Welding Machine Time and Current 40A

About this item

• The control panel of the spots welding machine is a controller which is independently developed for the DIY or the simple resistance welding. The principle of silicon controlled phase shifting triggering is adopted to adjust the time and the current to achieve the purpose of welding. Features: The use of STM8 industrial microcontroller control center. Strong and weak electricity through optocoupler isolation, safer operation. The power line and the foot switch line adopts the screw free quick connection terminal, more convenient and reliable. Input time, current using high-accurate SinglePotentiometer, to ensure reliable input. On-board power, state, foot, trigger indicator, working state clearly visible. The design of reliable zerocrossing detection circuit to ensure that the SCR phase shift accuracy. Digital control interface, you can display the current time and current settings.
