10101118 - Tweco Classic 1 MIG Gun 180A 12ft Velocity Series

Product Overview

The Tweco Classic No. 1 MIG Gun (SKU: 1010-1118) represents the evolution of one of the welding industry's most trusted tools. This air-cooled MIG gun is rated for 180 Amps at a 60% duty cycle when using CO2 shielding gas, making it a robust solution for light to medium-duty fabrication, automotive repair, and general maintenance applications. The unit comes equipped with a 12-foot cable assembly, providing sufficient reach for standard workbench environments and shop floors without compromising wire feedability.

Velocity Consumable Technology

A key technical enhancement in this model is the integration of the Velocity™ consumable series. Unlike traditional threaded contact tips, Velocity tips utilize a threadless, drop-in design that seats firmly into the gas diffuser. This design maximizes surface contact area, resulting in superior electrical conductivity and heat dissipation. The gas porting is optimized to ensure smooth laminar flow, reducing turbulence and improving shielding gas coverage. For the industrial user, this translates to fewer consumable changes, less downtime, and a more stable arc characteristic.

Construction and Compatibility

The gun features the signature Tweco heavy-duty construction. The conductor tube is metal-jacketed to withstand the rigors of daily shop use, resisting damage from drops or impacts. The cable assembly is reinforced to prevent kinking while maintaining flexibility for the operator. This specific model utilizes a standard Tweco rear connection, ensuring broad compatibility with a wide range of wire feeders and power sources that accept Tweco-style plugs. The ergonomic handle is designed to fit comfortably in the hand, featuring a responsive trigger mechanism that has been tested for high-cycle durability.

Specifications

The Tweco Classic No. 1 is designed to handle wire diameters typically ranging from .023" to .045", depending on the liner and contact tip configuration (ships with standard setup). It is an air-cooled unit, eliminating the need for external water coolers and hoses, which simplifies the equipment footprint. The 1010-1118 configuration is a complete ready-to-weld package, pre-assembled with the necessary liner and Velocity front-end parts to get you up and running immediately.
