42.0001.5129 - Fronius Conical Gas Nozzle 15mm ID x 79mm Length

Genuine Fronius Conical Gas Nozzle for Precision Welding

The Fronius Gas Nozzle Conical 15/025X79 (Part Number: 42.0001.5129) is a premium OEM consumable designed to maintain the high-performance standards of Fronius MIG/MAG welding systems. In the realm of industrial welding, the integrity of the gas shield is paramount to producing defect-free welds. This nozzle features a precision-engineered 15mm bore diameter, which provides a balanced laminar flow of shielding gas, effectively protecting the weld pool from atmospheric contamination such as nitrogen and oxygen. The conical geometry is specifically selected to offer welders improved visibility of the arc and the weld puddle, as well as better access to fillet welds and tight corners where cylindrical nozzles might cause obstruction.

With a length of 79mm, this nozzle is designed to establish the correct contact tip recess, which is critical for controlling stick-out and ensuring consistent electrical characteristics during the welding process. Manufactured from high-grade copper alloy, the nozzle exhibits excellent thermal conductivity, allowing it to dissipate heat rapidly during high-amperage applications. This thermal management helps prevent the adhesion of molten spatter, thereby extending the service life of the consumable and reducing the frequency of cleaning intervals. For automated and manual welding setups utilizing compatible Fronius torches (such as the MTG and MTW series), using genuine Fronius parts guarantees that the tolerance stack-up remains within factory specifications, preventing gas turbulence and porosity issues.

Josef Gas supplies this component to support fabrication shops that demand reliability. Whether working with carbon steel, stainless steel, or aluminum, the 42.0001.5129 nozzle is a staple consumable for maintaining arc stability and weld quality. Its robust construction withstands the rigors of industrial environments, making it a cost-effective choice for high-volume production lines.
