Generally, the current of 0.1-0.15 nickel-plated sheet welding is about 90-150A, so the working power supply of the circuit board must be greater than or equal to 150A.</span></p><p><br/></p><p><span style="font-size:18px"><strong>Parameter:</strong></span></p><p><span style="font-size:18px">Power supply voltage: 12V-15V</span></p><p><span style="font-size:18px">Working current: 100-200A</span></p><p><span style="font-size:18px">Note: It will not work if it is discharged below 100A.</span></p><p><span style="font-size:18px">A battery with a large discharge current will directly affect the welding effect.</span></p><p><br/></p><p><span style="font-size:18px"><strong>Instructions for use:</strong></span></p><p><span style="font-size:18px">Welding is an engineering discipline. Spot welding is affected by factors such as pulse time, welding angle, strength, and flatness of the welding surface, and the effect will vary.</span></p><p><span style="font-size:18px">When spot welding, just place the soldering pen on the nickel sheet lightly. Do not use force to press the soldering pen. The distance between the two soldering pins is a little closer. If the solder joint becomes black, lower the gear, and if the molten pool is too small, increase the gear.</span></p><p><span style="font-size:18px">Use blades, stainless steel bowls and other iron and stainless steel with larger surfaces before welding, and then weld the battery after familiarizing yourself with the operation.</span></p><p><br/></p><p><span style="font-size:18px"><strong>Instructions for use:</strong></span></p><p><span style="font-size:18px">Welding is an engineering discipline.
