100A Spot Welding Machine Time & Current Controller Panel Board – NY-D01 Digital Display SCR Powermeter for DIY Welders in Pakistan

Overview 

The 100A Spot Welding Time & Current Controller (NY-D01) is engineered for makers building custom AC resistance spot welding systems. Using an industrial STM8 microcontroller core, it employs sophisticated phase-shift triggering principles to control high-power AC transformers with extreme repeatability. Featuring dual digital displays for cycle time and current percentage, it allows you to tune your welds precisely for nickel strips, stainless steel, and battery interconnects without blowing through your material.

Key Features

• Precise Phase-Shift Control: Accurate SCR triggering backed by a robust zero-crossing detection circuit to ensure stable power delivery.

• Dual Digital Displays: Clear LED readout for managing time input (measured in cycles, where 1 cycle = 20ms) and current intensity percentage (30%–99%).

• High Safety Isolation: Strong and weak current pathways are completely separated via optical couplers to protect your low-voltage control side.

• Heavy-Duty 100A Thyristor Compatibility: Handles high surge loads smoothly when paired with an appropriate high-current step-down transformer.

• Foot Switch & Trigger Ready: Integrated control interface supports standard foot pedals and mechanical trigger switches for hands-free operation.
