Reduced！Amusingtao Spot Welding Machine 12V Welder Unassembled Battery Storage Solder Circuit Board

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.
