CX425-3545 - 400A Tweco Style MIG Torch with 25ft Cable and Euro Connector

Industrial Grade 400A MIG Welding Gun

The CX425-3545 is a robust air-cooled MIG welding gun designed for high-amperage industrial applications. Rated at 400 Amps, this torch is engineered to handle heavy fabrication tasks involving thick structural steel and extended arc-on times. The unit features a standard Euro back-end connection, making it a versatile replacement or upgrade for a wide variety of European and multi-process welding power sources that utilize this universal port standard.

One of the defining specifications of this assembly is its 25-foot (7.6-meter) cable length. This extended reach is critical for large-scale manufacturing environments, shipyards, and trailer fabrication, where moving the wire feeder or power source is impractical. The cable itself is constructed with high-grade copper stranding and a durable outer jacket designed to withstand the rigors of the shop floor, including abrasion, dragging, and exposure to hot sparks.

Technically, the gun is configured with a Tweco-style front end. This ensures compatibility with one of the most widely available consumable platforms in the industry. Maintenance teams can easily source contact tips, gas diffusers, and nozzles without relying on proprietary or hard-to-find parts. The gun comes pre-lined and set up for wire diameters ranging from .035" to .045", covering the most common range for structural MIG welding. The ergonomic handle design incorporates a reliable trigger mechanism tested for high cycle counts, ensuring longevity in production environments.
