Mini Welder Control Board 10-15V Stable Digital Spot Welder Module for Equipment Repair Specification: Item Type: Spot Welder Control Board Material: PCB Rubber ABS Purpose: Equipment welding Working Current: 100-300A Service Voltage: 10-15V Package List: 1 x Board 2 x Spot Welding Pens 2 x Connection Wires 1 x Nickel Sheet 4 x Screws 4 x Nuts 2 x Heat Shrink Pipe Sleeves 1 x Board Storage Box Note: 1. The user needs to provide 10-15V power supply by himself. The welding current is about 100-300A. For common 0.1-0.15mm plated sheet welding 2. If the discharge is lower than 100A it will not work. The battery with large discharge current the working current is greater than 300A will produce large sparks when it is used which will affect the welding effect and in serious cases it will to tube explosion and burning of the circuit board. 3. Suggestion: For power supply with current greater than 300A 40-60AH please use low power welding first in case of low electricity. If the effect is not gradually increase the gear.
