0700300604 - ESAB TXH 251F Replacement Flexible TIG Torch Body

ESAB TXH 251F Flexible Torch Head Overview

The ESAB TXH 251F Torch Head (SKU: 0700300604) is a specialized replacement component designed specifically for the TXH 251 series of air-cooled TIG torches. This unit serves as the core body of the torch, connecting the power cable and gas supply to the consumables. The 'F' designation indicates a flexible neck, a critical feature for industrial maintenance and fabrication environments where joint accessibility varies significantly.

Constructed from high-grade, heat-resistant silicone rubber and durable copper components, this torch head is engineered to withstand the thermal cycles associated with TIG welding at amperages typical of the TXH 251 class (generally rated up to 250A DC / 175A AC at specific duty cycles). The insulation material provides excellent dielectric strength and resistance to cracking, ensuring operator safety and equipment longevity. As an OEM part, it guarantees perfect thread compatibility with existing ESAB handles, back caps, and collet bodies, eliminating fitment issues often seen with generic replacements.

This component is essential for maintaining the operational readiness of welding stations. Over time, torch heads can degrade due to heat stress or mechanical damage. Replacing a damaged rigid head with this flexible version, or simply replacing a worn flexible head, restores the torch's performance and versatility. It is designed for air-cooled setups, relying on the flow of shielding gas and ambient air to dissipate heat generated during the welding arc.

Installation is straightforward, requiring the disassembly of the handle and disconnection of the power cable from the old head. The new TXH 251F head screws securely into the handle assembly, ensuring a gas-tight seal and reliable electrical connection. It is compatible with standard ESAB consumables utilized by the TXH series.
