Reliable Performance with Modern Technology

The Tweco Classic No. 1 MIG Gun (1010-1138) combines the legendary durability of the Classic series with the advanced performance of Velocity consumables.

Key Benefits for the Welder

• Proven Ergonomics: The Classic handle shape is a favorite among welders for its comfort and balance, reducing fatigue during extended use.


• Enhanced Conductivity: Velocity consumables utilize a large contact area to transfer current more effectively, resulting in smoother welds and longer consumable life.


• Durable Construction: Built with high-quality copper conductors and a rugged outer jacket, this gun withstands the rigors of the shop floor.

Whether you are welding mild steel, stainless, or aluminum (with the correct liner), the Tweco Classic No. 1 delivers consistent results. The 15-foot reach allows for flexibility around large workpieces without moving the power source constantly.
