0459990635 - ESAB MXL 200 MIG Torch Consumable Starter Kit (0.8-0.9mm)

Technical Overview

The ESAB 0459990635 is a specialized Wear Parts Kit engineered for the MXL 200 series of gas-cooled MIG welding torches. This kit aggregates the most frequently replaced front-end consumables, ensuring that operators have immediate access to critical components required for maintaining arc stability and gas shielding efficiency.

The kit is configured to support wire diameters of 0.8mm (0.030 inches) and 0.9mm (0.035 inches), covering the most common range for light-to-medium fabrication tasks. It includes M6 threaded contact tips, which are precision-machined from high-grade copper alloy to maximize electrical conductivity and wear resistance. The included gas nozzles feature a conical design, optimized to direct shielding gas flow precisely over the weld pool, minimizing porosity and oxidation.

Also included are nozzle springs (or retention springs), which are essential for securing the gas nozzle to the swan neck and ensuring proper electrical isolation where necessary. By using genuine ESAB OEM parts, users guarantee dimensional accuracy and thermal compatibility with the MXL 200 torch head, preventing issues such as overheating or loose connections that can occur with aftermarket generic replacements.
