NY-D01 100A Digital Display Spot Welding Controller Board

NY-D01 100A Digital Display Spot Welding Controller Board provides a precise and reliable solution for controlling the timing and power of DIY or professional spot welding machines. This sophisticated controller board effectively manages a high-current Triac, consequently delivering repeatable, high-quality spot welds necessary for battery pack assembly and sheet metal fabrication. The integrated digital display allows users to easily set pulse time and current percentage, offering granular control that standard timer boards cannot match. Therefore, using the NY-D01 greatly enhances the consistency and efficiency of any homemade spot welder, giving you the ability to fine-tune welding parameters for different materials and thicknesses.

Key Features:

• Digital Display Control: An intuitive digital tube display shows current time and power settings, providing precise, repeatable parameter configuration.
• High Current Capacity: The controller can manage up to a 100 A SCR (Triac) output, making it suitable for powerful spot welding transformers.
• Time and Current Adjustable: Users can independently adjust the welding time (0.02 s to 1 s) and welding power (30% to 99%) for optimal results.
• Zero-Crossing Detection: Features zero-crossing detection, which effectively ensures stable output current and minimizes electromagnetic interference (EMI).
• Universal Compatibility: You can easily adapt the board to control 9 V to 12 V AC power input transformers commonly used in DIY spot welders.

Pinout and Wiring:

• Input Power (AC 9-12V): Connect the secondary winding (9V-12V) of your power transformer here to energize the controller.
• SCR/Triac Output: Connect the gate and cathode terminals of your external high-current Triac/SCR to this terminal block for control.
• Switch Input: Connect a momentary footswitch or button here to initiate the welding sequence.
• Display/Adjustment: The integrated display and buttons allow for setting Time (T) and Current Percentage (P) parameters.
• Primary Transformer Control: This board does not directly handle the welding transformer’s primary power; instead, it drives an external Triac that switches the transformer’s primary winding.

Commonly Used in:

• DIY Spot Welders: Forms the brain for custom-built, high-performance battery spot welders.
• Lithium Battery Pack Assembly: Ensures precise, low-heat welds required for connecting nickel strips on 18650, 21700, and other battery cells.
• Small-Scale Fabrication: Used for bonding thin metal sheets or wires in hobby and light industrial settings.

Applications:

• Nickel Strip Welding: Precisely welds nickel and nickel-plated steel strips onto battery terminals.
• Jewelry and Wire Welding: Enables consistent joining of small metal components where low heat input is critical.
• Educational Projects: A key component in teaching power electronics and precise timing control.

Equivalent Models:

• NY-D02 / S-D06: These are similar single-pulse and dual-pulse timing spot welder controllers, however, the NY-D01 focuses on simplicity and robust single-pulse control.
• Various STM8-based Welding Timers: Many low-cost welding controllers utilize the same chip, although the exact display and button configuration may differ.
