Spot Welder for Time Control Board 40A Current Controller with Digital Display

Description: This version for mass production without flying version. The package contains the control panel, display panel, cable matching, red green button. The shop has a pedal, welding needle, open the copper nose mouth, quick plug joints, heat shrink tubing and other accessories, power for transformers, (red line input 220V, black line (Huang Xian) to the panel control output (choose to join the shopping cart to bring together) Because of the ease of consumption of silicon controlled parts, easy to discriminate in the commissioning process, it is recommended that friends together spare parts, easy to replace. please choose your own. The control panel of the spot welding machine is a controller that is independently developed for DIY or simple resistance welding. the trigger phase shift controlled silicon principle is adopted to adjust the for time and current to achieve the welding target. The main features of this controller: 1: The use of STM8 industrial control center microcontroller. 2: Strong and weak electricity through optocoupler insulation, safe operation. 3: The power line and foot switch line adopts the bolt the quick connect terminal, more convenient and reliable. 4: Input for time, current using high-precision simple potentiometer, to ensure reliable, convenient input 5: On-board power supply, state, foot, trigger indicator, work status clearly visible. 6: The design of reliable zero crossing detection circuit to ensure that the SCR phase shift accuracy. 7: The controller is for 40A scr. 8: Digital control interface, you can display the current for time and current settings. 9: Input for time of 1-50, cycle unit (1 cycles is 20 ms), current input (30-99%), Note: Please allow 1-3mm errors due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
