Tweco Classic No. 5 MIG Gun – 500A, 15ft, Lincoln Style

Upgrade your welding setup with the Tweco Classic No. 5 MIG Gun (1050-1642), the heavy-hitter of air-cooled MIG torches. Engineered for high-deposition welding, this gun is capable of handling 500 Amps (using CO2) or 400 Amps (using mixed gas) at a 60% duty cycle. It is the go-to choice for flux-cored and solid wire applications where heat management and durability are critical. This assembly features a 15-foot cable and a Lincoln backend connection, ensuring seamless integration with your existing Lincoln power sources.

Rugged Construction & Easy Maintenance

The Classic No. 5 is built to last. It features a simplified, field-repairable design that allows welders to service the gun quickly right on the shop floor. The cable assembly uses high-quality copper stranding for efficient current transfer and is protected by a tough outer jacket. The connection to the wire feeder is reinforced with a heavy-duty steel spring strain relief, preventing cable failure at the most common stress point.

Consumable Compatibility

One of the biggest advantages of the Tweco Classic platform is its consumable system. This gun accepts the industry-standard Tweco heavy-duty front-end parts:

• Contact Tips: Compatible with 14 Series (standard) and 15 Series (heavy duty).
• Nozzles: Fits 24 Series (slip-on) and 25 Series (adjustable) nozzles.
• Diffusers: Uses 54 and 55 series gas diffusers.

With its ergonomic handle, high duty cycle, and proven track record, the Tweco Classic No. 5 remains the preferred choice for welders tackling thick plate and heavy structural projects.
