The Tweco\u00ae Professional Classic\u00ae No. 4 MIG Gun is a legend in the welding industry, trusted by fabricators for over 40 years. Designed for durability and performance, this 400-amp air-cooled gun is the go-to choice for medium to heavy-duty welding applications. Whether you are working in a production line, a maintenance shop, or on a farm, the Classic No. 4 delivers consistent results with solid, flux-cored, and aluminum wires. This specific model comes equipped with a 15-foot cable and a Miller\u00ae style rear connector, making it a direct replacement or upgrade for compatible Miller wire feeders.<\/p>\n
One of the standout features of the Tweco Classic series is the ergonomic oval-shaped handle.

Additionally, a convenient gun hanger located at the bottom allows for safe and easy resting when the tool is not in use.<\/p>\n

The Classic No. 4 features a split-half handle case, allowing for quick and easy field repairs without the need for specialized tools.
