OVERVIEW

Heavy-Duty Flux Core Welding Solution

The Tweco SEFC350 Flux Core MIG Gun (SKU: 10311643) is a high-performance welding torch engineered specifically for the demands of Flux-Cored Arc Welding (FCAW). Rated at 350 Amps, this gun is designed to handle high-deposition welding applications found in heavy fabrication, structural steel construction, and shipbuilding. The unit features a 15-foot cable assembly, providing operators with the necessary reach to access large workpieces without compromising wire feedability.

Constructed with industrial-grade materials, the SEFC350 is built to withstand the intense heat and spatter associated with flux-cored welding. The gun utilizes a standard Tweco back-end connection, ensuring compatibility with a wide range of wire feeders and power sources equipped with Tweco receptacles. This standardization simplifies integration into existing equipment fleets and reduces the need for specialized adapters.

Maintenance and consumable management are streamlined thanks to the gun's compatibility with standard Tweco front-end parts. This includes contact tips, gas diffusers, and nozzles (or thread protectors for self-shielded applications), which are widely available and easy to replace. The robust cable design ensures consistent electrical conductivity and shielding gas flow (if applicable), contributing to stable arc performance and high-quality welds.

Key Technical Specifications:

  • Amperage Rating: 350 Amps
  • Cable Length: 15 Feet
  • Connection Type: Tweco Style
  • Application: Flux-Cored Arc Welding (FCAW)

For industrial operations requiring a reliable, high-amperage torch for flux-cored applications, the Tweco SEFC350 offers a proven balance of durability, performance, and ease of maintenance.
