100A/40A LCD Display Welder g DIY Board

Description: Can be set to save the last operation the module turn off of time you can change to . The main board and the display operation panel are separated and the outer casing can be flexibly . Multi-group data 12864 visual display intuitive operation convenient single adjustment can make the operation simple and fast. With grid voltage compensation the output of compensation can be automatically adjusted according to the change of and the electric voltage of about 1 second can be displayed when ed so that the effective heat of welding is consistent with the welding s and the welding uniform. With 0-9999 welding counting function with 5 groups of storage s can even the electricity power is off the number of wleding could be seen just by a glance. Time input 0-99 cycle (1 cycle is 20ms for example the adjustment value is 50 which is the welding time 1 second.) the stop time between 2 weldings is 0-99 cycles (1 cycle is 20ms such as interval value 50 It is the interval of 1 second.) adjustable. Welding strength 30%- adjustable. The module can isolate the strong and weak electricity by optical coupling and design a reliable circuit for zero-crossing detection and voltage detection to ensure the accurate phase of silicon control (SCR) which can be compatible with 40A-100A bidirectional silicon control (SCR). 9-12 input The power input and external adopt convenient and quick welding free terminal the external can be diversified the has anti- ing to the end of welding for one round. Package Includes: 1 Welder Controller Board
