B&O 100A LCD Display Digital Double Pulse Encoder Spot Welder Controller Board Spot Welder Control Module

The spot welder control module is developed for DIY or simple battery welder. It is mainly used for single battery or battery group nickel plated sheet welding, such as 18650 lithium battery nickel plating 0.15 and 0.2mm steel sheets, transformer above 500W can be welded directly. It is intended to weld other battery materials and different thickness, such as polymer battery electrode without nickel plating, must be combined with sufficient power transformer to weld. This module includes main board and display board, optional 40A and 100A bidirectional silicon control rectifier, does not include welding transformers, welding pen and other matching tools. Features: Can be set to save the last operation, the module double pulse trigger, turn off any set of trigger time, you can change double pulse to single pulse trigger. The main board and the display operation panel are separated, and the outer casing can be flexibly assembled Multi-group data 12864 visual display, intuitive operation, convenient, single encoder parameter 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 power supply, and the electric voltage of about 1 second can be displayed when triggered, so that the effective heat of welding is consistent with the welding parameters, and the welding spot is uniform. With 0-9999 welding counting function, with 5 groups of sample storage parameters, can be stored even the electricity power is off, the number of welding could be seen just by a glance. 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 shift of silicon control rectifier (SCR), which can be compatible with 40A-100A bidirectional silicon control rectifier (SCR). The power input and external trigger adopt convenient and quick welding free terminal, the external trigger can be diversified, such as normal switch, foot switch, external signal source input, etc., the software has anti-lock state, triggering to the end of welding, for one round.  For example, the pedal switch has been trampled all the time, can only trigger one round.
