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 offerirectional silicon control tectifier, does not include welding transformer, welding pen and other matching tools.
Three groups of data digital tube display
Grid voltage compensation function
0-999 welding counting function
Time input 0-99 cycle
Welding strength 30%-99%, adjustable
9-12 V AC power input
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 offerirectional silicon control rectifier (SCR).
1 x 100A/40A Digital LCD Single Pulse Encoder Spot Welder Time Control Board
1. This module DIY needs to have certain electrician knowledge.
2. The power of the module driving load depends on the power of silicon control rectifier (SCR). BAT41 (40A) can carry a microwave oven transformer, BAT100 (100A) can carry two microwave oven transformer, and the recommended one for Loop transformer is 100A.
3. Do not know the welding time and power of the welded parts, it is recommended that the welding time and power be adjusted from small to upper to avoid damage to the welding pen.
