CS310A - Weldcraft W-310 (CS310A) Replacement TIG Torch Body, Water-Cooled

Technical Overview of the Weldcraft CS310A

The Weldcraft CS310A is a specialized replacement torch body designed for the W-310 series (formerly known as the CS310 Crafter Series) of TIG welding torches. Engineered by Miller Weldcraft, this component serves as the core structural and conductive element of the torch assembly, facilitating the transfer of welding current while managing thermal loads through an integrated water-cooling system. The unit is rated for a TIG welding output of 310 amperes, making it suitable for medium-to-heavy industrial fabrication tasks where duty cycles and heat management are critical operational parameters.

Constructed with a rigid head style, the CS310A prioritizes durability and precise electrode alignment. The body features mechanical (threaded) connections for the interface with power cables, water hoses, and gas lines. This mechanical connection style is distinct from crimped or soldered connections, offering the advantage of easier maintenance and component replacement in the field. The internal water chambers are designed to maximize flow rate and heat exchange, ensuring that the torch handle and consumables remain within safe operating temperatures during prolonged welding arcs at high amperages.

As a genuine OEM component, the CS310A ensures full compatibility with existing W-310 and CS310 consumables, including collets, collet bodies, and gas lenses. It maintains the ergonomic profile of the original torch, preserving the operator's dexterity and control. The use of high-grade copper alloys and temperature-resistant insulating materials in the manufacturing of this torch body contributes to its longevity and resistance to thermal shock. For maintenance and repair operations (MRO), utilizing the correct torch body specification is essential for maintaining the safety rating and performance characteristics of the welding system.

The CS310A is specifically identified for water-cooled applications. Attempting to operate this torch body without an active coolant circulator will result in immediate overheating and catastrophic failure of the internal power cable connections and seals. It is designed for professional industrial environments requiring consistent 310A performance.
