44.0350.3426 - Fronius MTW 500i Heavy Duty Contec Gas Nozzle

Premium Fronius Gas Shielding for MTW 500i Systems

Maximize the performance of your Fronius welding equipment with the Fronius Nozzle Contec HD (44.0350.3426). Designed explicitly for the high-performance MTW 500i water-cooled MIG torch series, this nozzle represents the pinnacle of precision engineering and durability in the welding consumables market. When working with sophisticated welding systems like those from Fronius, using genuine or high-specification replacement parts is critical to maintaining the arc stability and weld quality that the machine was designed to deliver.

The "Contec" designation refers to a specific geometry and design philosophy used by Fronius to optimize the flow of shielding gas around the contact tip and weld pool. This ensures that the molten metal is perfectly protected from atmospheric contamination, reducing porosity and oxidation. Furthermore, the "HD" (Heavy Duty) rating indicates that this nozzle is built with robust materials capable of enduring the extreme thermal cycles associated with high-amperage, water-cooled welding applications. This durability translates directly to cost savings by reducing the frequency of consumable replacements.

In industrial environments where downtime is costly, the reliability of the 44.0350.3426 nozzle is a significant asset. Its surface finish and material composition are selected to resist spatter adhesion, meaning welders spend less time cleaning their torch and more time welding. Whether you are fabricating heavy structural steel, working in automotive manufacturing, or performing precision alloy welding, this nozzle ensures your gas coverage remains laminar and effective.
