10441142 - Tweco 400A Water-Cooled Push-Pull Gun, 20ft, 1/16 Wire

Precision Aluminum Welding Solution

The ESAB 10441142 is a specialized industrial Push-Pull MIG gun designed to address the unique challenges of feeding soft welding wires, particularly aluminum, over extended distances. Engineered under the robust Tweco product line, this 400-Amp water-cooled torch system provides a reliable solution for heavy fabrication environments where duty cycle and wire feed consistency are critical. The unit comes pre-configured for 1/16-inch (1.6mm) wire, making it immediately applicable for structural aluminum work, shipbuilding, and trailer manufacturing.

The core advantage of this system lies in its synchronized push-pull mechanics. A motor located in the gun handle works in tandem with the wire feeder at the power source to maintain constant tension on the wire. This eliminates the compression forces inside the liner that typically cause buckling or "bird-nesting" when pushing soft aluminum wire through standard MIG guns. The result is a smooth, chatter-free arc start and consistent deposition rates, even when the 20-foot cable is curved or looped.

Thermal management is handled via an efficient water-cooling system, allowing the gun to operate at 400 Amps with a 100% duty cycle. This is essential for high-amperage spray transfer modes often used in thick-section aluminum welding. The cooling system also keeps the handle temperature low, significantly improving operator comfort and safety. The backend is fitted with a standard Tweco connection, ensuring seamless integration with compatible ESAB and Tweco power sources or feeders equipped with the appropriate receptacle.

Constructed for durability, the cable assembly features a rugged outer jacket that resists abrasion, oil, and cuts common in shop environments. The ergonomic handle design balances the weight of the internal drive motor, minimizing wrist strain during prolonged welding operations. This product represents a high-tier solution for professional fabricators requiring distance, power, and precision.
