This is a 12V Battery Storage Spot Welding Machine Circuit Board. Spot welding is welded by the principle of rapid local heating and cooling by high current. This Product is much portable and durable that it can easily be carried anywhere.

The circuit board of this spot welder can be used for welding 18650/26650/32650 lithium batteries. A battery with a large discharge current will directly affect the welding effect. If the battery capacity is greater than 45Ah it is recommended to extend the battery wire 80cm to avoid buming the tube due to current overload.

• Working Current(A): 30-150
• Supply Voltage(V): 12-14.6
• Recommended Battery Capacity: 30-45Ah
• Length (mm): 80
• Width (mm): 45
