34356 - ESAB PT-15XL Replacement Water Injection Hose 17ft

Technical Overview of the ESAB 34356 Water Injection Hose

The ESAB 34356 is a specialized replacement water injection hose designed exclusively for the PT-15XL plasma cutting torch. This component plays a pivotal role in the operation of water-injection plasma systems, a technology where water is introduced directly into the plasma arc to constrict it. This constriction significantly increases the energy density of the arc, resulting in cleaner, squarer cuts and extended consumable life compared to standard dry plasma processes. The hose measures 17 feet in length, matching the standard lead assembly length for many PT-15XL configurations, ensuring a seamless integration into existing cable management systems.

Constructed from high-grade, durable materials, this hose is engineered to withstand the specific pressures and chemical environments associated with plasma cutting coolants and water injection systems. In an industrial setting, hoses are subject to constant movement, bending, and potential abrasion; the ESAB 34356 is built to resist these stressors to prevent leaks. A leak in the water injection line can lead to catastrophic failure of the torch head, poor cut quality due to lack of arc constriction, or electrical faults if fluid bridges the gap between high-voltage components. Therefore, maintaining the integrity of this hose is essential for the safe and efficient operation of the plasma cutter.

This item is an Original Equipment Manufacturer (OEM) part. Using OEM parts for the PT-15XL is highly recommended to ensure that flow rates and pressure tolerances meet the exact specifications of the power source and torch design. Generic hoses may not possess the correct internal diameter or flexibility, potentially leading to flow restrictions or installation difficulties. The 34356 ensures that the water injection mechanism functions exactly as intended, cooling the nozzle bore and shielding the workpiece from excessive heat affected zones (HAZ).

Installation of the 34356 involves routing the hose through the torch lead assembly. Technicians should ensure that all connections are tight and that the hose is not kinked or pinched during the reassembly of the cable cover. Regular inspection of this hose during routine maintenance intervals is advised to detect early signs of wear, such as cracking or hardening of the tubing material.
