2-2592 - Tweco PWM-4A 400 Amp MIG Gun, 25ft Cable, Offset Handle

Industrial Grade 400A MIG Welding Gun

The Tweco 2-2592 PWM-4A MIG Gun is a high-performance welding tool designed for heavy-duty industrial applications. Engineered to deliver a consistent 400 Amps of welding current, this air-cooled gun is built to withstand the rigors of structural steel fabrication, heavy equipment manufacturing, and shipyard environments. The 'PWM' designation typically denotes a professional-grade configuration, ensuring that the tool meets the demands of continuous operation at high parameters.

One of the standout specifications of this model is its 25-foot cable assembly. In many industrial settings, the ability to weld at a significant distance from the power source is crucial for productivity. Standard 10 or 15-foot guns often require the welder to constantly reposition the wire feeder or welding machine, wasting valuable arc time. The 25-foot reach of the PWM-4A allows operators to navigate around large workpieces, such as truck bodies, large vessels, or structural beams, with freedom and ease.

The gun features an offset handle design, which is ergonomically engineered to provide a more natural hand position during welding. This reduces operator fatigue, particularly during long weld runs or when welding in difficult positions. The connection type is the industry-standard Tweco style (often referred to as T&L or Tweco/Lenco), ensuring compatibility with a vast range of wire feeders and adapters. The gun utilizes standard Tweco consumables—contact tips, gas diffusers, and nozzles—which are renowned for their durability and widespread availability, making inventory management simple for shop managers.

Constructed with high-quality copper cabling and durable outer jacketing, the cable assembly resists cuts, abrasion, and burns from hot slag. The heavy-duty strain relief systems at both the gun handle and the rear connector prevent cable kinking and protect the internal copper strands and liner from damage, ensuring a long service life and consistent wire feeding performance.
