0700200055 - ESAB MXL 270 Standard Gas Nozzle 15mm (10-Pack)

Precision Shielding for Professional Fabrication

The ESAB Gas Nozzle Standard 15mm (Part Number 0700200055) is a critical consumable component designed exclusively for the ESAB MXL 270 MIG welding gun. In the realm of Gas Metal Arc Welding (GMAW), the gas nozzle plays a pivotal role in directing the shielding gas—typically Argon, CO2, or a mixture thereof—over the weld pool. This 15mm standard nozzle is engineered to provide the optimal balance between gas coverage and accessibility, making it the go-to choice for a wide variety of standard welding applications.

Manufactured from high-quality copper alloy, this nozzle is built to withstand the intense thermal cycling inherent in industrial welding processes. The material's superior thermal conductivity aids in rapid heat dissipation, preventing the nozzle from overheating during prolonged duty cycles. This thermal management is essential not only for the longevity of the nozzle itself but also for protecting the front-end consumables of the MXL 270 gun, such as the contact tip and tip adapter.

The 15mm bore diameter is considered the industry standard for medium-to-heavy duty welding. It creates a column of shielding gas that is sufficiently wide to protect the molten puddle from atmospheric nitrogen and oxygen, which can cause porosity and brittleness in the weld metal. At the same time, the profile is streamlined enough to allow the operator to access tighter joints without compromising the gas shield. Precision machining ensures a secure fit onto the MXL 270 torch neck, preventing gas leaks that could lead to turbulence and aspirated air entering the weld zone.

Supplied in a convenient package of 10, this product ensures that fabrication shops and maintenance departments can maintain a steady inventory of essential consumables. Regular replacement of gas nozzles is a best practice in welding quality assurance; over time, spatter buildup can distort the gas flow, and physical deformation from drops or knocks can disrupt the laminar flow required for X-ray quality welds. By choosing genuine ESAB parts, operators ensure compatibility and performance consistency across their welding operations.
