This circuit with 12V battery will become a storage spot welding machine for lithium battery, nickel-chromium battery and other nickel sheet welding, according to different configurations can be welded thickness of 0.1MM-0.15mm.
The button can switch modes. Each mode corresponds to different welding time. The LED corresponds to red/green/blue/white/yellow/powder/purple, 7 modes, the shortest red time and the largest purple welding time. Long press to set the waiting time, the default is 3 seconds, the maximum can be set to 10 seconds
Basic parameters :
- Supply voltage: 7V-12V (capacity X rate = must be greater than 150A)
- Current requirements: 150A or more instantaneous output (such as car starter power supply, 3S RC high-power battery pack, 20A lead-acid battery with good performance above 20A)
The 18650 battery and DC power cannot be used as a power supply. It must have a high rate RC battery or a car battery! ! !
Notice: Capacitors must be welded or instant restart will cause MOS break down!!!
Requires certain welding technology and circuit knowledge. The parts received are parts, which need to be assembled by welding
Before welding , please do power on test first to make sure the board is in good condition . Pay attention to the positive and negative poles when wiring. Please do not use a 2-wire soldering tool .when using the 3 wire iron, note that the soldering iron must be grounded ,or there will be a risk to break though the Mos. The mini capacitance should be welded on the PCB board as below picture showed.
What you Get:
1 x PCB Welding Board V3 set
