OVERVIEW

Rugged, Reliable, and Ready to Weld

Equip your welding station with the Tweco Classic No. 4 MIG Gun, the preferred choice for welders who demand toughness and reliability. This 400-Amp air-cooled gun features a 15-foot cable and a Euro-style connection, providing a seamless upgrade or replacement for any machine equipped with a Euro receptacle. Known for its ergonomic curved handle and balanced feel, the Classic No. 4 reduces operator fatigue during long shifts, making it a favorite among career welders.

The 10401603 model is engineered for versatility and power. It comes ready to run .035" to .045" solid or flux-cored wires, making it perfect for general fabrication, manufacturing, and maintenance repair operations (MRO). The air-cooled design is efficient and low-maintenance, eliminating the potential for water leaks associated with water-cooled systems while still maintaining a high amperage rating suitable for spray transfer and globular transfer modes.

Technical Excellence & Compatibility

This gun utilizes the world-renowned Tweco consumable platform. It features:

14 Series Contact Tips: Available in various geometries for optimal arc stability.
24 Series Gas Nozzles: Adjustable slip-on nozzles for easy cleaning and stick-out adjustment.
54 Series Gas Diffusers: Durable brass construction for excellent conductivity.

The cable assembly is constructed with high-quality copper stranding for maximum current transfer and flexibility. A sturdy steel spring strain relief at the handle and a durable cable support at the rear connection prevent kinking and wire feed issues. If you need a MIG gun that can take a beating and keep on welding, the Tweco Classic No. 4 is the proven solution.

FAQ

The Tweco Classic No. 4 is rated at 400 Amps at a 60% duty cycle when using CO2 shielding gas. When using mixed gases (like Argon/CO2), the duty cycle or amperage rating may be slightly lower due to the different thermal properties of the gas.

This specific model (10401603) features a Euro-style back-end connection. This is a single plug that connects power, gas, and trigger control, commonly found on many Esab, Fronius, and European-style welding machines.

This gun comes pre-configured with a liner and contact tip setup for .035" to .045" (0.9mm to 1.2mm) welding wire.

Yes, but you will need to change the liner to a polymer or Teflon liner to prevent wire shaving and feeding issues. You may also need specific aluminum contact tips.

It uses standard Tweco consumables: 14 Series contact tips, 24 Series nozzles, and 54 Series gas diffusers.

The Tweco Classic No. 4 is an air-cooled MIG gun. It relies on the shielding gas and ambient air to dissipate heat.

This model comes with a 15-foot (approximately 4.6 meters) cable assembly.

Yes, the conductor tube (gooseneck) is replaceable and can be rotated or changed to different angles (e.g., 45 or 60 degrees) depending on operator preference.
