A cylindrical battery transistor gantry spot welder is a precision welding machine designed for the battery industry. It is specifically used to perform spot welding on cylindrical batteries like 18650, 21700, and nickel-plated tabs, terminal connections, and other battery components. The machine uses a fast-rising transistor power supply, which allows for rapid welding with minimal heat impact, making it perfect for ultra-precise welding tasks.

Key Features

1. Fast Welding Current Rise
   The transistor-based power supply enables a rapid rise in welding current, completing the welding process quickly with minimal thermal impact. This feature is ideal for ultra-precise welding tasks such as fine wires, button cell connections, small relay contacts, and metal foils.

2. Three Control Modes
   The machine offers three flexible control modes:

   • Constant Current Control

   • Constant Voltage Control

   • Combination of Constant Current and Voltage Control
     These modes provide flexibility for different welding needs, ensuring precise and reliable results.

3. Large LCD Display
   The machine is equipped with a large liquid crystal display that shows the welding current, power, and electrode voltage, allowing operators to easily monitor and adjust the welding parameters.

4. Built-in Detection Function
   Before power is applied, the machine can verify the presence and condition of the workpiece, ensuring only suitable materials are welded.

   
   

Applications

1. Battery Industry

   • Battery caps, nickel strips, battery tabs, and other components are welded in the production of NiMH, NiCd, and Li-ion batteries.

2. Automotive and Motorcycle Components

   • Suitable for welding terminal ends, wire harnesses, magnet wires, and precision wiring in electric vehicles and motorcycles.

3. Electronics and Electrical Components

   • Welding silver contacts, lead wires, gold-plated surfaces, and various electronic components, such as resistors, capacitors, LEDs, and plugs.

     
     

How to Use It

1. Setting Up the Machine

   • Begin by configuring the appropriate welding parameters, such as current, voltage, and control mode (constant current, voltage, or a combination).

   • Place the workpiece between the welding electrodes and align it properly.

2. Initiating the Welding Process

   • Press the Start button or footswitch to initiate the welding process. The machine will automatically monitor and adjust welding parameters in real time for consistency.

3. Post-Welding Inspection

   • After welding, the built-in detection system automatically checks the quality of the weld. If the weld is unsuccessful, the system will alert the operator and provide feedback.

     
     

Automated Process Flow

1. Preparation

   • Load the cylindrical battery components (e.g., nickel strips, tabs) into the machine. Set the welding parameters based on material and thickness.

2. Welding

   • The machine initiates the welding process using precise control over current and voltage, ensuring high-quality welds.

3. Verification

   • After welding, the system checks the quality of the weld. If there are any issues, the machine will stop and notify the operator.

4. Completion

   • The machine finishes the welding process and ejects the completed product for further processing or packaging.
