Battery Energy Storage Spot Welder Machine Control Board Small PCB Circuit Board DIY Portable Welding Equipment Spot Welders Pen Accessory

MOS core operating temperature: 175 ℃
VDS: withstand voltage up to 40V
RDS (on): the internal resistance of a single capsule is as low as 0.77 Mr
LD: single overcurrent capacity 300A

Suitable for welding cylindrical lithium battery

Power supply battery selection:
1: 12V lead-acid electricity: 20-40AH, 70% to 80% of the new can be used, once it exceeds 40AH, it cannot be used directly, please consult customer service.
2: 2S or 3S model aircraft battery, capacity x discharge rate > 100A, and the discharge current should not exceed 250A.
3: 12V car starting power supply, the instantaneous starting current should not exceed 300A.
4: 12V lithium battery pack: capacity x discharge rate > 100A, and the discharge current should not exceed 250A.
5: Farad capacitors and transformers cannot be used for power supply, and the currents of these two devices are uncontrollable. (In the range of rated voltage (DC 7-16V), rated current (100-300A))

Attention:
1. After the system is powered on, the nixie tube displays 0. At this time, welding is not allowed. The output power needs to be adjusted through the button (gear 1-8).
2. It is recommended that the power supply voltage is 7v-16v and the working current is 100-300a. Exceeding this range may damage the control board.

Package Include:
1 x Mini portable spot welder kit

10awg wire rod, alumina copper needle solder joint, ensuring high current throughput and durability, high frequency capacitor, low internal resistance, high temperature resistance.
Ultra thick copper tube pure copper conducts electricity and heat to improve spot welding efficiency.
High frequency capacitor has low internal resistance and can withstand high temperature of 105 ℃.
8 gear power regulation, nixie tube real-time display gear.
Positive and negative marks are not easy to connect wrong wires, bilateral outgoing lines are convenient for spot welding
