Tweco Tuff-N-Lite TL350 MIG Gun Overview

The Tweco Tuff-N-Lite TL350 MIG Gun (SKU: 1036-1037) is a premium air-cooled welding torch designed for medium to heavy-duty industrial applications. Engineered by Tweco, a leader in arc welding accessories, this gun is part of the renowned Tuff-N-Lite series, which is celebrated for delivering high-amperage performance in a package that is significantly lighter than comparable models. This specific configuration features a 15-foot (4.5-meter) cable and is pre-setup to run 1/16-inch (1.6 mm) welding wire, making it an ideal choice for structural steel fabrication, heavy equipment manufacturing, and flux-cored arc welding applications.

At the core of the TL350 is its impressive 350 Amp rating at 60% duty cycle using CO2 gas. This power capacity ensures the gun can handle sustained welding operations without overheating, providing consistent arc stability and weld quality. The gun utilizes a standard Tweco-style rear connection, ensuring seamless compatibility with a vast array of wire feeders and power sources that utilize this industry-standard termination. The direct connection design maximizes electrical conductivity and minimizes voltage drop across the system.

Maintenance and consumable management are simplified with the TL350. It utilizes standard Tweco consumables, including the widely available 14 Series contact tips, 24 Series gas nozzles, and 54 Series gas diffusers. This ubiquity of parts means that shops can easily stock replacements without sourcing specialized or proprietary components. The gun's construction features a rugged, impact-resistant handle and a heavy-duty cable jacket designed to withstand the rigors of the shop floor, including resistance to abrasion, hot sparks, and oils.

Operator comfort is a priority in the Tuff-N-Lite design. The handle is ergonomically shaped to fit naturally in the welder's hand, reducing grip strain and wrist fatigue during extended use. The cable assembly includes sturdy spring strain reliefs at both the gun handle and the feeder connection, preventing kinking and protecting the internal copper stranding and liner from damage. Whether you are welding mild steel, stainless, or aluminum (with the appropriate liner change), the Tweco TL350 delivers reliable, professional-grade performance.
