Description

100A/40A LCD Display Spot Welder DIY Transformer Board Time Control Timer
Description:
Can be set to save the last operation, the module double pulse , turn off any set of time, you can change double pulse to single pulse .
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 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 of silicon control (SCR), which can be compatible with 40A-100A bidirectional silicon control (SCR).
9-12 V AC power input
The power input and external adopt convenient and quick welding free terminal, the external can be diversified, the software has anti-lock state, triggering to the end of welding, for one round.
Package Includes:
1 x Spot Welder Transformer Controller Board
