Spot Welder Set 12V DIY Portable Spot Mini Welding Set For 18650 26650 32650 Battery

Description:
Suggested Battery: 20-45ah battery with good performance and small internal resistance; 3.5-5.5ah 45C 3S aeromodel battery pack; 30-35ah capacity battery pack.
Voltage: This circuit with a 12V battery will become an energy storage spot welding machine for welding nickel pieces.
Design: The MOS upper and lower bold and tin design makes the internal resistance smaller and the current stronger.
Thickness: According to different configurations, the thickness can be about 0.1mm-0.15mm.
More Stable: Using 25V low internal resistance Sanyo high frequency capacitors to make the power supply more stable.
Tip:
If the battery is pretty good and the internal resistance is very low, and then there may be large current overload.
If you are not sure about your battery, it’s better to extend the wire by around 1 meter with 2.5² or 4² wire, then it will reduce the risk of power tube burnt.
