Description
The Magnum PRO Curve guns are perfect for MIG or flux - cored welding. They combine a classic curved handle with Copper Plus contact tips and Magnum PRO gun expendables. This combination allows for long - lasting fabrication welding with fewer changes of tips and gun expendable parts.
- Lincoln Electric Copper Plus Contact Tips: With a larger tip diameter and mass, they dissipate heat better, which extends the tip's lifespan.
- Curve Handle Design: The lightweight and well - balanced curved handle offers a comfortable grip, reducing user fatigue.
- Rotating Gun Tube and Gun Hanger Clip: They provide multiple hand positions, reducing fatigue and enabling use in tight spaces.
- Simplified Expendable Parts Selection: The 350A and 550A consumables can be used interchangeably across all gun models. All models come with 350A parts.

Using the Lincoln Magnum Pro Curve 400 Semi - Automatic MIG Gun is quite straightforward. First, make sure to select the right consumable parts according to your welding needs. You can use either 350A or 550A consumables as they are interchangeable. Just note that all models are shipped with 350A parts. When welding, hold the gun by the curved handle. Its lightweight and balanced design will give you a comfortable grip. You can adjust your hand position using the rotating gun tube and gun hanger clip to reduce fatigue or fit into tight spots. As for maintenance, since the Copper Plus contact tips have a larger diameter and mass, they dissipate heat well and have a long lifespan. But still, check them regularly for wear and tear. Replace the tips and other expendable parts when they show signs of significant damage. Keep the gun clean to ensure smooth operation. That's about it, and you'll be able to use this gun for long - hours of fabrication welding with ease.
