10201128 - Tweco Classic No. 2 MIG Gun, 200A, 10ft, Miller Connection, Velocity Consumables

Product Overview

The Tweco Classic No. 2 MIG Gun (Part Number: 1020-1128) represents a fusion of time-tested structural design and modern consumable technology. This air-cooled MIG welding gun is rated for 200 Amps at a 60% duty cycle using CO2 gas, making it an ideal choice for medium-duty industrial fabrication, maintenance, and repair operations. The unit features a 10-foot cable assembly, providing adequate reach for standard bench work while minimizing cable clutter in tighter workspaces.

A key technical differentiator for this specific model is the integration of Velocity™ consumables. Unlike traditional threaded contact tips, Velocity tips utilize a threadless, drop-in design with a larger surface area for electrical contact. This results in significantly improved heat dissipation, cooler operating temperatures, and extended consumable life. The gas flow path is also optimized in the Velocity platform to ensure better shielding coverage and reduced porosity in the weld deposit.

The rear connection is engineered specifically for Miller® wire feeders, featuring the standard Miller power pin configuration. This allows for immediate plug-and-play installation on compatible Miller power sources without the need for additional adapters. The gun assembly includes a heavy-duty copper conductor tube and a durable outer jacket designed to withstand abrasion and impact in harsh shop environments. The trigger mechanism is designed for longevity, capable of withstanding hundreds of thousands of cycles, ensuring reliable arc initiation every time.

Technical Specifications

This gun is designed to handle wire diameters typically ranging from .023" to .045", depending on the liner and contact tip installed. The 10ft cable utilizes high-quality copper stranding to minimize voltage drop, ensuring that the voltage set at the machine is delivered to the arc. The strain relief systems at both the handle and the feeder end are robust, preventing kinking and protecting the internal gas hose and power cable from damage during manipulation.
