The Tweco Classic No.1 MIG Gun (SKU: 10101127) represents the evolution of one of the welding industry's most trusted tools. Designed for light to medium-duty fabrication, this 180-amp air-cooled gun combines the legendary durability of the Tweco Classic handle with the advanced performance of Velocity™ consumables. This specific configuration features a 15-foot cable assembly and a Miller-style rear connection, making it an ideal direct replacement or upgrade for compatible Miller welding power sources.
What sets this version of the Classic No.1 apart is the integration of the Velocity consumable system. Unlike traditional front-end parts, Velocity contact tips are threadless and feature a "drop-in" style that seats firmly into the gas diffuser. This design creates a solid copper conductor path that optimizes electrical conductivity and heat transfer. The result is a cooler-running tip that lasts longer and provides a more stable arc, reducing downtime associated with tip changes and burn-backs.
Built to withstand the rigors of daily industrial use, the gun features a heavy-duty cable with a durable outer jacket that resists cuts, abrasion, and oil. The metal-jacketed conductor tube is rotatable, allowing welders to adjust the neck angle for better access to tight joints. The trigger mechanism is designed for longevity, providing positive feedback and reliable engagement over thousands of cycles. With a 60% duty cycle at 180 amps using CO2 gas, this gun is perfectly sized for automotive repair, sheet metal fabrication, and general maintenance applications.
The Miller-style rear connection ensures a plug-and-play experience for users with Miller wire feeders and integrated MIG machines. The 15-foot lead offers ample freedom of movement around large workpieces without compromising wire feedability. Whether you are welding mild steel, stainless steel, or aluminum (with the appropriate liner), the Tweco Classic No.1 delivers consistent wire delivery and superior gas coverage.
