20Z30 - CW-23 Water-Cooled TIG Torch Body 500A

Heavy-Duty Water-Cooled TIG Torch Head

The ESAB 20Z30 is the genuine replacement torch head (body) for the legendary CW-23 TIG welding torch system. Designed for heavy-industrial applications, this water-cooled head is engineered to handle high amperage loads while maintaining a compact and manageable profile. The CW-23 series has long been a standard in the industry (formerly under the Linde and L-Tec brands) for automated and manual welding where heat management is critical. This specific component forms the core of the torch assembly, housing the collet body and directing shielding gas and cooling water to the nozzle area.

Constructed from high-grade conductive alloys and high-temperature resistant insulation materials, the 20Z30 head ensures efficient current transfer and effective heat dissipation. It is rated for 500 Amps DCSP (Direct Current Straight Polarity) at a 100% duty cycle, making it suitable for welding thick sections of aluminum, stainless steel, and mild steel. The water-cooling channels are precision-machined to maximize flow rate and thermal exchange, preventing overheating even during prolonged welding arcs. This reliability is essential for fabrication shops, pipe welding, and manufacturing environments where equipment failure leads to costly downtime.

Installation of the 20Z30 is straightforward for technicians familiar with the CW-23 platform. It connects directly to the standard handle and cable assemblies associated with this model. By using genuine ESAB parts, operators ensure proper fitment and seal integrity, preventing coolant leaks that could compromise the weld quality or damage the power cable. This head is compatible with standard CW-23 front-end consumables, including collets, collet bodies, and gas cups, allowing for seamless integration into existing inventory.
