10271391 - Tweco SG200 TA-25 Spool Gun for Fabricator 252i - 25ft Cable

Technical Overview of the Tweco SG200 TA-25 Spool Gun

The Tweco SG200 TA-25 Spool Gun (SKU: 1027-1391) is a specialized MIG welding accessory engineered specifically for use with the Thermal Arc / Tweco Fabricator 252i power source. This unit is designed to address the mechanical challenges associated with feeding soft welding wires, such as aluminum, over long distances. By locating a heavy-duty drive motor directly on the gun handle, the SG200 eliminates the friction and buckling issues commonly found in standard push-style MIG torch setups. The unit features a direct-plug connection, ensuring immediate compatibility with the 252i's control circuitry and gas output without requiring external adapter boxes or complex wiring modifications.

Technically, the SG200 is rated for 200 Amps and is capable of handling wire diameters of 0.035" (0.9mm) and 0.045" (1.2mm). The drive roll system is optimized for precision, accommodating 4-inch diameter spools. This allows for the use of 1 lb spools of aluminum wire or 2 lb spools of mild steel, stainless steel, or silicon bronze. The gun assembly weighs approximately 6.4 lbs, a metric that balances structural durability with operator ergonomics. The 25-foot (7.6 meter) cable assembly includes the power conductor, gas hose, and trigger leads, all encased in a protective sleeve to resist abrasion and environmental damage in industrial settings.

The package is supplied as a complete turnkey solution. It includes a robust carrying case and a starter kit of consumables derived from the standard Tweco 11 Series contact tips and 51 Series gas diffusers. The inclusion of both steel and Teflon jump liners ensures that the operator can configure the gun for the specific material being welded, preventing wire contamination or feeding irregularities. This spool gun is an essential component for fabrication environments requiring reliable, high-mobility aluminum welding capabilities paired with the Fabricator 252i platform.
