10311637 - Tweco SEFC 350 Gasless Flux-Cored Gun, 10ft, Miller Connector

Industrial Grade Tweco SEFC 350 Flux-Cored Gun

The Tweco SEFC 350 is a high-performance welding gun designed specifically for self-shielded flux-cored arc welding (FCAW-S). Engineered to meet the rigorous demands of heavy industrial environments, this 350-amp gun provides reliable arc stability and durability. It is particularly effective for structural steel erection, heavy equipment repair, and general fabrication where gas shielding is impractical or unavailable.

This model features a direct Miller-style back end connection, allowing for immediate compatibility with a wide range of Miller wire feeders and power sources without the need for adapters. The 10-foot cable assembly is designed to balance reach with wire feedability; shorter cables are often preferred for flux-cored wires to minimize friction and bird-nesting, and 10 feet offers an optimal compromise for mobility and performance.

The gun is configured to handle wire diameters from 0.030" to 0.035", making it versatile for various plate thicknesses and welding positions. Its air-cooled design is robust and simple to maintain, reducing downtime on the job site. The ergonomic handle and strain relief systems are built to withstand the mechanical stresses of daily use while providing the welder with comfort and control.
