Tweco 1040-1111 Classic 4 MIG Gun - 400A, 10ft, Tweco Connection

Equip your welding station with the Tweco Classic No. 4 MIG Gun, part number 1040-1111. This air-cooled torch is engineered for high-amperage MIG welding applications, offering a robust 400 Amp rating suitable for flux-cored and solid wire welding on thick materials. The 10-foot cable length is perfect for bench work or jig welding where excessive cable slack is unnecessary, helping to maintain a tidy workspace and improve wire feedability.

Technical Specifications & Compatibility

The 1040-1111 is outfitted with a Tweco-style rear connection, the most common connection type in the North American market, ensuring plug-and-play compatibility with Lincoln, Miller, ESAB, and other feeders equipped with Tweco adapters. The gun is factory-configured for 1/16" (1.6mm) wire, utilizing a specific liner and contact tip setup optimized for this diameter. However, the gun is fully adaptable and can be converted to run wire sizes ranging from .035" to 5/64" with the appropriate consumables.

Consumable System

This MIG gun utilizes the industry-standard Tweco consumable platform, which is widely available and cost-effective. It uses:

• 14 Series Contact Tips: Heavy-duty tips designed for excellent electrical conductivity and wear resistance.
• 24 Series Gas Nozzles: Adjustable slip-on nozzles that allow for easy cleaning and stick-out adjustment.
• 54 Series Gas Diffusers: Durable brass diffusers that ensure smooth gas coverage.

Durability and Maintenance

The Classic No. 4 is built with a metal-jacketed conductor tube (gooseneck) that resists damage from drops and impacts. The air-cooled power cable features a coaxial design that maximizes current carrying capacity while remaining flexible. Maintenance is straightforward, with a simple hex-screw design allowing for quick disassembly of the handle and replacement of the trigger or cable. For welders who require a no-nonsense, high-performance tool that can take a beating and keep on welding, the Tweco Classic No. 4 is the definitive choice.
