10201119 - Tweco Classic No. 2 MIG Gun, 200A, 25ft, Tweco Connection, Velocity Consumables

Tweco Classic No. 2 MIG Gun Overview

The Tweco Classic No. 2 MIG Gun (Part No. 1020-1119) represents the evolution of one of the welding industry's most trusted tools. Rated for 200 Amps at 60% duty cycle (using CO2), this air-cooled gun is designed for medium-to-heavy duty fabrication applications. This specific configuration features a generous 25-foot cable, providing exceptional reach for working around large assemblies without moving the wire feeder. It terminates in a standard Tweco-style rear connection, ensuring compatibility with a vast array of power sources and wire feeders that utilize this common connection standard.

A key enhancement in this model is the integration of Velocity™ consumables. Unlike traditional threaded tips, Velocity consumables feature a threadless, drop-in style contact tip that seats firmly into the gas diffuser. This design optimizes electrical conductivity and heat transfer, resulting in a more stable arc and significantly longer consumable life. The conductor tube is metal-jacketed, offering superior protection against impact and heat compared to standard plastic-insulated necks.

The cable assembly is constructed with high-quality copper stranding and a durable outer jacket that resists cuts, abrasion, and oil. The handle is ergonomically shaped to reduce operator fatigue during long shifts, and the heavy-duty trigger is engineered to withstand harsh industrial environments. Maintenance is straightforward, with easily replaceable liners and modular components.
