0700200158 - ESAB PSF 410W/510W Replacement Support Hose - 4.5m

Technical Replacement for PSF Water-Cooled Systems

For professional welders and maintenance technicians operating ESAB PSF 410W and PSF 510W water-cooled MIG guns, the 0700200158 Support Hose is the exact OEM replacement required for the 4.5-meter cable assembly. Water-cooled torches are the workhorses of heavy fabrication, designed to handle high amperages and high duty cycles. The cooling system is the lifeline of these torches; if the support hose carrying the coolant or protecting the lines becomes compromised, the torch can overheat in seconds, leading to catastrophic failure of the power cable or swan neck.

This specific hose is engineered to meet the precise flow and pressure requirements of the PSF cooling circuit. It features the correct diameter and flexibility to route through the cable assembly without kinking, which is a common issue with non-OEM replacements. Kinks in a water hose can starve the torch head of coolant, causing the power cable to burn out inside the line. This 4.5-meter hose ensures consistent flow dynamics and maintains the ergonomic flexibility of the torch, reducing welder fatigue during long shifts.

Key Technical Benefits:

• Exact Fitment: Designed strictly for the PSF 410W and 510W series, ensuring connectors and strain reliefs fit securely.
• Thermal Stability: Material composition is selected to resist hardening or cracking due to thermal cycling from hot coolant and external welding heat.
• Abrasion Resistance: The outer skin is tough enough to handle the rigors of shop environments, protecting the integrity of the fluid channel.

When rebuilding a PSF torch or addressing a coolant leak in the cable assembly, verify your cable length is 4.5 meters before ordering. This component is integral to the "Support" structure of the cable, often acting as the conduit for water return or supply depending on the specific generation of the PSF torch. Installation requires disassembly of the handle and machine-end connector; ensure all O-rings and connections are seated properly to prevent leaks after replacement.
