1. Spot welding utilizes the principle of rapid local heating and cooling by high current. 2. Sufficient current is required; generally, the welding current for 0.1 to 0.15 nickel-plated plates is approximately 90 to 150 A. 3. The following batteries are recommended: a 12V automotive jump starter and a 3S high-power battery for model aircraft. 4. Three high-power lithium batteries, such as 40900 3-pin batteries, offer good performance and are rated above 12V 20A. 5. Capacity x discharge rate = charge capacity. For example, a 5200mA air battery has a discharge rate of 35C. Specification: Condition: 100% Brand New Item Type: Spot Welder Pen.
