0.08~0.2mm Nickel strip spot welder for 18650 lithium-ion battery pack

Product description:

The spot welder for 18650 lithium-ion battery has a small welding transformer, but the output is large, increasing the inverter frequency from 50/60Hz to 4000Hz, and converting the power to DC power for welding through the rectifier diodes in the transformer.

This battery spot welding machine is modular in design and important components include the inverter, welding controller and medium frequency transformer. In addition, a microcomputer multifunctional controller with two analog/digital conversion circuits is equipped to automatically adjust the power supply voltage changes and ambient temperature changes to maintain stable output.

Features:

1. It adopts DSP chip control and has two working modes: constant voltage command output and constant current output.

2. Primary sampling feedback at the 1 μs level guarantees constant current output.

3. The inverter bridge uses soft switching technology to reduce switching losses and reduce electromagnetic interference.

4. The current abnormal sound and light alarm to prevent false welding.

5. High operating frequency, low transformer loss, energy saving.

6. 30 sets of welding parameters can be stored for quick switching between different products.

7. Digitally set welding parameters, easy and convenient to operate.

Scope of application:

The spot welder for 18650 lithium-ion battery cells is suitable for battery pack assembly, such as power-tool battery, street light battery, EV battery, electric motorcycle battery. The welding material can be either pure nickel strip or nickel-plated steel, with the following thickness requirements.
