Double Nob display card

Double Knob Digital Display Control Card

Dual Function Control | Real-Time Display | Enhanced Versatility

The Double Knob Display Card is a precision-engineered electronic control board designed for modern welding machines (MMA, MIG, TIG) and industrial automation systems. Equipped with two independent rotary knobs, this board allows simultaneous control of multiple parameters such as current, voltage, arc force, or wire feed speed, depending on application.

An integrated digital LED display, status indicator LEDs, and protected circuit design make this an ideal solution for OEMs and service engineers.

🔧 Key Features:

• 🔘 Dual Potentiometer Knobs – Enables separate control of current and arc force/voltage

• 🔢 3-Digit LED Display – Displays real-time output values and error codes

• 💡 Multi-Color Indicator LEDs – Instant visual status of operation and fault conditions

• 🧠 Microcontroller-Based Design – Ensures stable output and responsive adjustments

• 🔌 Plug-and-Play Terminals – Easy to connect with power boards, sensors, and switches

• 🛡️ Built-in Protection – Overcurrent, thermal, and short-circuit safety
