Advantages: convenient Carry, stable, reliable and durable. Low cost, own car start battery, or high-power battery pack, connect it Ready to use! Save production cost! Users need to bring their own 12V battery for power supply, and the welding current is about 90A~130A. For common 0.1mm~0.12mm nickel plated sheet welding is easy. Please make sure your battery can have more than 90A Current, otherwise it will not be possible to weld! Power supply voltage: 12V-15V Working current: 90-150A (discharge below 90A, it will not work.) A battery with a large discharge current will directly affect the welding effect. The following batteries are recommended: 20-45ah lead-acid battery with good performance and small internal resistance (internal resistance is less than 10 milliohms, and the discharge current is greater than 90A), such as starting the battery in a new car! 3.5-5.5ah45C 3S model airplane lithium battery pack 30-35ah capacity 18650 battery pack Power requirements: Spot welding is welded by the principle of rapid local heating and cooling by high current, Need sufficient current supply, generally used 0.1-0.15 nickel plated sheet welding current About 90-150A, so the working power of the circuit board must be greater than or equal to 150A. The following battery packs can be used as working power 12V car starter power, 3S high-rate battery pack for model airplane, three-string high-rate lithium battery pack, Hitachi 409003 string battery pack, lead-acid battery with good performance above 12V20A. Calculation formula: capacity X discharge rate = load capacity Take 4000ma aeromodelling battery as an example, the discharge rate is 45C (4AX45C=180A) Instructions f.Find many great new \u0026amp; used options and get the best deals for DIY 12V Battery Energy Storage Spot Welder Machine PCB Circuit Board 18650 NEW at the best online prices at Order2india Shopping!
