2117834 - ESAB Oxweld C-66 Machine Torch Head 90 Degree Replacement

Technical Overview of the ESAB C-66 Head 90 (2117834)

The ESAB 2117834 is a specialized replacement component designed for the C-66 series of machine cutting torches. This unit, identified as the "C-66 Head 90," provides a 90-degree orientation for the cutting tip relative to the torch barrel, which is the standard configuration for vertical cutting in automated oxy-fuel systems. Manufactured to the rigorous specifications of the Oxweld legacy line now under the ESAB brand, this head assembly is critical for maintaining the geometric precision and gas flow dynamics required for high-quality plate cutting.

Constructed from high-grade brass, the head is engineered to withstand the intense thermal cycling and reflected heat inherent in heavy industrial cutting operations. The internal geometry of the head is precision-drilled to ensure laminar flow of preheat gases (oxygen and fuel) and the high-pressure cutting oxygen stream. Turbulence within the head can lead to distorted flame characteristics and poor cut quality; therefore, replacing a damaged or carbon-fouled head with this genuine ESAB part is essential for restoring optimal process control. The seating surfaces for the cutting tips are machined to exact tolerances to prevent gas leaks, which are a primary cause of flashbacks and sustained backfires.

This component is fully compatible with the modular design of the C-66 machine torch, allowing for straightforward field replacement without the need to replace the entire torch assembly. It supports the full range of Oxweld cutting tips compatible with the C-66, making it versatile for various fuel gases including acetylene, propane, and natural gas, depending on the injector and tip selection. Industrial maintenance planners and procurement specialists should verify the torch model number before ordering, but for existing C-66 installations requiring a 90-degree down-cutting configuration, the 2117834 is the direct OEM replacement part.

In automated environments, mechanical damage to the torch head is common due to plate tip-ups or collisions. Having a spare 2117834 in inventory ensures minimal downtime. The head connects securely to the torch barrel, maintaining electrical continuity for systems utilizing height sensing technology, and provides a robust mounting point for the cutting tip nut. This part represents the intersection of durability and precision engineering, characteristic of ESAB's offering in the heavy cutting sector.
