The Weldotherm DIGIT 700 is a robust and highly precise digital temperature controller designed specifically for the rigorous demands of industrial heat treatment. As a core component of Weldotherm’s world-renowned heating systems, the DIGIT 700 ensures that critical thermal processes, such as preheating and post-weld heat treatment (PWHT), are executed with absolute precision.

Specialized for Thermal Processing

• Ramp and Soak Programming: Allows operators to define complex heat treatment cycles with multiple segments for controlled heating, soaking, and cooling rates.
• Dual LED Interface: Provides immediate and clear visibility of the Actual Value and the Setpoint, even in dimly lit industrial environments.
• Optimized for Type K Sensors: Engineered to work seamlessly with Type K (NiCr-Ni) thermocouples, the industry standard for high-temperature metal processing.

Durability and Reliability

• German Engineering: Manufactured to withstand the electromagnetic interference and vibration often found in heavy engineering and construction sites.
• Precision PID Control: Advanced algorithms prevent temperature overshoot, which is vital for maintaining the structural integrity of specialized alloys during stress relief.
• User-Friendly Operation: Despite its advanced capabilities, the interface is designed for intuitive use by field technicians.

Typical Applications

• Post-weld heat treatment of large-diameter pipes
• Stress relieving of welded structural components
• Preheating for critical welding operations
• Industrial furnace and oven control
