Description
The Lincoln Magnum PRO Curve guns are perfect for MIG or flux - cored welding. They combine a classic curved handle with Copper Plus contact tips and high - quality Magnum PRO gun expendables. This combination allows for long hours of fabrication welding with fewer tip and gun expendable part changes. Here are the key features:
- Lincoln Electric Copper Plus Contact Tips: Their larger diameter and mass enhance heat dissipation, significantly increasing tip life.
- Curve Handle Design: The lightweight and well - balanced curved handle offers a comfortable grip, reducing user fatigue.
- Rotating Gun Tube and Gun Hanger Clip: These features provide multiple hand positions, reducing fatigue and enabling use in tight spaces.
- Simplified Expendable Parts Selection: 350A and 550A consumables are interchangeable across all gun models, and all models come with 350A parts.

Using the Lincoln Magnum Pro Curve 400 Semi - Automatic MIG Gun is straightforward. First, make sure it's properly connected to your welding machine. Then, choose the right welding wire and adjust the settings according to your project. Hold the gun with the curved handle for a comfortable grip. You can rotate the gun tube to find the best hand position. When welding, keep a steady motion for a smooth weld. For safety, always wear appropriate protective gear like welding gloves and a mask. As for maintenance, regularly check the contact tips. Since they have good heat dissipation, they last a long time, but still need to be inspected. If you notice any wear, replace them. Also, keep the gun clean from dust and debris. Remember, the 350A and 550A consumables are interchangeable, so you can easily switch parts as needed.
