3-2646-23 - Thermal Dynamics WC-100B Plasma Arc Welding Controller

Precision Plasma Welding Control

The Thermal Dynamics WC-100B Welding Console is a critical component for professionals seeking to perform high-quality Plasma Arc Welding (PAW). Designed to interface seamlessly with compatible DC power sources, this console acts as the brain of your plasma welding operation. It manages the complex variables required for plasma welding, including the pilot arc, plasma gas flow, and shielding gas flow, ensuring a stable and constricted arc that delivers deep penetration and narrow heat-affected zones.

One of the standout features of the WC-100B is its integrated pilot arc power supply. Unlike standard TIG welding where the arc is established directly between the electrode and the workpiece, plasma welding relies on a pilot arc to ionize the gas stream before the main arc is transferred. The WC-100B handles this initiation sequence flawlessly, utilizing a high-frequency starting circuit to establish the pilot arc without contaminating the electrode or the workpiece. This results in consistent starts every time, which is essential for automated applications or high-value component repair.

The front panel is designed for ease of use, featuring dual flowmeters that allow the operator to independently adjust the plasma gas (center gas) and the shielding gas. This dual-gas capability is vital for tailoring the arc characteristics to specific materials and thicknesses. Whether you are welding micro-fittings in the semiconductor industry or performing tool and die repairs, the granular control provided by the WC-100B ensures optimal results. The unit also includes safety interlocks that monitor coolant flow and gas pressure, protecting both the expensive torch components and the console itself from damage due to setup errors.

Built with the durability expected from Thermal Dynamics, the WC-100B is housed in a rugged enclosure suitable for industrial environments. It supports a variety of torch models and can be configured for different amperage ranges depending on the power source it is paired with. By adding the WC-100B to your welding arsenal, you unlock the full potential of the plasma process, gaining the ability to weld thinner materials at lower amperages with greater stability than conventional TIG welding allows.
