12V Spots Welding Machine Control Board DIY Set Nickel Plated Sheet 5 Gears Spot Welder Nickel Sheet For 18650 Lithium Battery
The main parameters:
Supply voltage: 12V-15V
Working current: 100-200A
Note: Discharge below 100A will not work,
A battery with a large discharge current will directly affect the welding effect.
Instructions for use:
Welding is an engineering discipline. Spot welding is affected by pulse time, welding angle, strength, flatness of the welding surface and other factors, and the effect will be different.
When spot welding, place the welding pen lightly on the nickel sheet. Do not press the welding pen with force. The welding distance between the two welding needles is a little closer. If the solder joint becomes black, lower the gear, and if the molten pool is too small, increase the gear.
Before welding, use iron and stainless steel with large surfaces such as blades and stainless steel bowls to try it out first, and then weld the battery after you are familiar with the operation.
Interface definition: Please strictly follow the instructions for wiring, the wrong connection may cause the circuit board to burn out
Function keys: used to switch the machine on and off, switch gears
Press and hold the function key to power on, and the first gear is defaulted. Press and hold the function key for 2 seconds to release, the gear will increase by one gear, and the buzzer will sound and the LED will flash corresponding to the number of gears.
Example: In the 3rd gear, the buzzer sounds 3 times and the LED flashes 3 times.
There are 5 gears in total. From gear 1 to gear 5, the spot welding strength is gradually strengthened, and gear 5 is the strongest. After the 5th gear, long press the function key to turn off the power.
Note: The buzzer needs to be installed by the user, and it will not affect the welding if it is not installed.
