0700200191 - ESAB MXH 400W PP Replacement Swan Neck Assembly

High-Performance Water-Cooled Torch Body for Aluminum Welding

The ESAB Torch Body Complete Mxh 400Wpp (SKU: 0700200191) is a premium replacement neck assembly engineered specifically for the ESAB MXH 400W PP push-pull MIG gun. This component is the heart of the front-end assembly, directing the welding wire, shielding gas, and coolant to the weld zone. Designed for heavy-duty industrial applications, this water-cooled torch body is rated for 400 Amps, making it ideal for high-deposition welding where thermal management is critical. The efficient water cooling circuit integrated into the body ensures that the nozzle and contact tip remain at optimal operating temperatures, significantly reducing consumable wear and preventing spatter adhesion.

For welders specializing in aluminum fabrication, the integrity of the push-pull system is paramount. The MXH 400W PP system relies on a synchronized drive mechanism to feed soft aluminum wire without buckling. The torch body plays a crucial role in this process by providing a smooth, low-friction path for the wire as it exits the gun handle. Any deformation or internal roughness in the neck can lead to feeding issues. This genuine ESAB replacement part is manufactured to exacting tolerances, ensuring a seamless transition for the wire and stable arc characteristics. It is particularly suited for industries such as shipbuilding, trailer manufacturing, and automotive fabrication where long reach and consistent wire feeding are required.

Installation of the 0700200191 torch body is straightforward, designed to interface perfectly with the MXH handle assembly. The connection points for power, water, and gas are precision-machined to prevent leaks, which can compromise weld quality (porosity) or safety. By using OEM parts, you maintain the safety rating and duty cycle of your equipment. This complete body assembly includes the necessary insulation and structural components to get your torch back in service quickly.
