- Connect compressed air to the cutting gun.
- Adjust air pressure using the regulator.
- Adjust cutting current as needed as shown below.
5. Execution and Cutting
Begin cutting by triggering the torch. Follow proper techniques for hand torch cutting. Practice piercing when necessary. When cutting aluminum, keep the torch perpendicular to the sheet’s surface, touch the metal with the torch tip to ignite it, and guide the arc along the cutting line. The plasma cutter will efficiently cut aluminum within some time.
Ensure you execute each step properly to achieve safe plasma cutting of aluminum.
6. Post-Cut Inspection
After completing the cutting process, inspect the edges for accuracy and smoothness. Use specific tools such as a wire brush to remove debris. Ensure a thorough post-cut inspection to maintain the quality of your work.
Tips for Precision
When we talk about precision while using a plasma cutter for aluminum, there are some techniques we need to master. Take a look at some of the tips for precision while plasma-cutting aluminum:
1. Optimal Speed and Angle
If you’ve got an idea of how to cut aluminum, you must know how to balance speed and angle. For that, you must maintain a steady pace while moving the plasma cutter torch. Also, maintain a consistent angle relative to the sheet’s surface. This may take some time, but keep experimenting with angles and speed till you achieve your target.
2. Consumable Maintenance
Keep inspecting the consumables such as nozzle, shield, and electrode from time to time. Ensure that they’re free of debris to get smooth cuts.
3. Choosing the Right Plasma Cutter
When selecting the plasma cutter for aluminum cutting, it’s important to consider specialized options tailored for this purpose. VEVOR offers a range of high-quality plasma cutters that cater to aluminum cutting needs. Among them, the VEVOR 50Amp Non-Touch Pilot Arc Plasma Cutter stands out for its pilot arc technology, ensuring stable and consistent cutting. The built-in air compressor of the CUT-40Z 40 Amp Air Plasma Cutter enhances portability and efficiency, making it a reliable choice for aluminum projects. Additionally, the VEVOR Plasma Cutter, 50 Amp, Non-Touch Pilot Arc Air Cutting Machine is designed for ease of use and efficiency, featuring a heat emission hole for steady performance. When exploring VEVOR’s plasma cutter options, carefully assess each product’s features to ensure they align with the specific requirements of aluminum cutting, ultimately ensuring optimal efficiency and precision.
4. Effective Torch Height Control
