40A/100A Digital LED Digit Tube Display Time Control Double Pulse Encoder Machine Controller Spot Welder Module Board

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 sheet, 500W transformer 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 optional 40A and 100A bidirectional silicon control rectifier (SCR), does not include welding transformers, welding pen and other matching tools.

Feature:
1. 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%-99% is adjustable.
2. 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).
3. 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. 
4. Usage: Welding of a single battery or battery pack.
