OVERVIEW

Lincoln Electric Magnum PRO AL: The Ultimate Push-Pull Solution

Elevate your aluminum welding performance with the Lincoln Electric Magnum PRO AL Pistol Grip Push-Pull MIG Gun, K3478-2. This air-cooled, 25-foot gun is designed to optimize push-pull welding operations, integrating features that significantly reduce downtime and improve weld quality. Whether you are in automotive body repair, boat manufacturing, or general aluminum fabrication, the K3478-2 delivers the consistent wire feeding required for X-ray quality welds.

The core advantage of this gun is its superior push-pull wire feeding technology. By reducing friction in the wire feed path, it ensures smooth delivery of soft aluminum wire, minimizing damage and shaving, which are common causes of liner clogging and arc instability. The gun is rated for 220 amps at a 60% duty cycle, making it ideal for a wide range of production applications. It comes ready to weld with 0.035" and 3/64" drive rolls and contact tips, utilizing the heavy-duty Magnum PRO consumable platform. These consumables are designed to withstand high heat and abuse, meaning fewer tip changes and more arc-on time.

User comfort is paramount in the Magnum PRO AL's design. The lightweight handle features a balanced pistol grip that fits naturally in the hand, suitable for both right and left-handed welders. A conveniently located recessed adjustment dial allows for easy parameter control at the gun, while its placement prevents unintended changes. For maintenance, the tool-less drive roll cover and Quick-Change liner system make servicing the gun fast and simple, keeping your production line moving.

Why Choose the K3478-2?

  • Reliable Reach: 25-foot cable length allows access to large weldments without moving the machine.
  • Magnum PRO Expendables: Uses common, high-amperage consumables available at Welders Supply.
  • Versatile Connection: Native 12-pin connection integrates seamlessly with Lincoln Electric industrial feeders and welders.
