3-2646-14 - Thermal Arc WC-100B Plasma Welding Controller

Precision Plasma Welding Control

The Thermal Dynamics WC-100B Welding Console (Part Number: 3-2646-14) is a sophisticated control unit designed to transform a standard DC Constant Current (CC) power source into a high-performance Plasma Arc Welding (PAW) system. This console serves as the central command interface for the plasma process, managing the critical functions that distinguish plasma welding from traditional TIG methods. It houses an internal pilot arc power supply, which maintains a low-current arc within the torch to facilitate instant transfer to the workpiece, ensuring reliable starting even in automated applications.

Engineered for precision, the WC-100B features dual flowmeters prominently mounted on the front panel. These allow the operator to independently regulate the flow rates of the plasma gas (orifice gas) and the shielding gas. This dual-gas control is essential for shaping the arc, controlling penetration, and protecting the weld pool from atmospheric contamination. The unit also incorporates a high-frequency arc starting circuit, providing non-contact ignition to prevent tungsten contamination. Safety is paramount in the design, with built-in interlocks that monitor coolant flow and gas pressure, automatically disabling the system if parameters fall outside safe operating limits to prevent torch burnout.

The console is designed for versatility and can be paired with various Thermal Arc plasma torches. It requires a 115 VAC input for operation and connects to the welding power source via standard control cables. By adding the WC-100B to your equipment lineup, you gain the ability to perform high-quality, constricted-arc welding suitable for aerospace, medical device manufacturing, and other industries requiring exacting weld standards.
