100A Digital Lcd Double Pulse Encoder Spot Welder Machine Time Control BoardLJJ

DIY or simple battery welder development welding. Welding of a single battery or battery pack. Multi-group data 12864 visual display, intuitive operation, convenient, single encoder parameter adjustment can make the operation simple and fast. 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 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%-99% is 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 shift of silicon control rectifier (SCR), which can be compatible with 40A-100A bidirectional silicon control rectifier (SCR). 9-12 V AC power input (using AC transformers, other such as DC, can cause zero-crossing detection failure, can not trigger.) colour:green Material:Metal + PC Package Contents: 1 * Main Board 1 * Display Board 1 * Cable
