10401171 - Tweco WeldSkill 400A MIG Gun, 15ft, Flex Head, Tweco Connection

Technical Overview

The Tweco WeldSkill 400A MIG Gun (Part Number 1040-1171) is a high-performance air-cooled GMAW torch designed for industrial fabrication environments requiring significant amperage capacity and positional versatility. Rated at 400 Amps at a 60% duty cycle using CO2 gas, this gun bridges the gap between value-oriented equipment and heavy-duty industrial demands. The defining technical feature of this specific model is the integrated Flexible Conductor Tube (Flex CT). Unlike standard rigid goosenecks, the Flex CT allows the operator to manually articulate the torch head to navigate complex geometries and obstructed weld joints without compromising gas coverage or wire feedability.

The assembly includes a 15-foot cable utilizing Tweco's proven coaxial cable design, ensuring efficient current transfer and durability against shop floor abrasion. The rear termination is a standard Tweco-style connection, making it compatible with a vast array of wire feeders and power sources equipped with Tweco adapters. The gun is engineered to utilize standard Tweco consumables, specifically the widely available 14 Series contact tips and 54 Series gas nozzles, simplifying inventory management for MRO departments. The handle geometry is optimized for the WeldSkill series, providing a balance of grip comfort and trigger responsiveness suitable for prolonged welding shifts.
