Hypertherm is a leading manufacturer of plasma cutting systems, and their products are commonly used in various industries for precision cutting of metal. Hypertherm’s plasma systems utilize electrical energy to generate a high-temperature plasma arc, which can be used to cut through electrically conductive materials.
To power a Hypertherm plasma system is comprised of the following:
Power Supply:
Hypertherm plasma systems require a dedicated power supply unit that can provide the necessary electrical energy to create and sustain the plasma arc. The power supply converts the input power from your facility’s electrical source into a suitable form for the plasma cutting process. It is important to take note of your building’s power configuration when selecting your system to ensure that the appropriate power supply is available.
Hypertherm Plasma Torch:
A Hypertherm plasma torch is the handheld or mechanized device that directs the plasma arc to the material being cut. It includes consumable parts, such as electrodes and nozzles, which may need to be periodically replaced to maintain optimal cutting performance.
Maintaining these consumables in a timely manner is imperative in preserving performance as well as extending the life of your CNC.
Gas Supply:
Plasma cutting requires a specific type of gas, usually air, oxygen, nitrogen, or a combination of gases, depending on the material being cut and the desired cutting quality. The gas is typically supplied through the torch and forms a part of the plasma arc. They Hypertherm System comes with four Gas Supply Set up options: Four gas connect console options offer unmatched mild steel cut quality with each console delivering successively enhanced cutting capabilities on stainless steel and aluminum. All consoles can be fully controlled through the CNC for high productivity and ease of use. CorePlus, VWI, and Optimix gas connect consoles provide a source of argon gas which can be used for significantly improved marking and extended capacity piercing in some applications.
To power the Hypertherm plasma system, you would typically connect the power supply unit to an appropriate electrical power source, following the manufacturer’s instructions. The power supply unit will then convert the electrical power into the required form to generate the plasma arc. The plasma torch is connected to the power supply unit and is ready to be used for cutting metal.
Maintaining the pilot arc is critical in equipment performance.
It’s important to note that specific instructions and requirements may vary depending on the model and type of Hypertherm plasma system you are using.
Preventative Maintenance:
Proper maintenance of the Hypertherm System is paramount to achieve optimal performance.
Monitoring coolant levels is one of the easiest ways to keep your system performing.
Maintaining the pilot arc on a plasma cutter is important for achieving consistent and reliable cuts. The pilot arc is a low-intensity electrical discharge that creates a path of ionized gas between the electrode and the workpiece, enabling the main cutting arc to be initiated.
Here are some tips for maintaining the pilot arc on a plasma cutter:
- Clean the torch: Before starting any cutting operation, ensure that the plasma torch is clean and free from debris. Any buildup of dust, metal shavings, or other contaminants can interfere with the pilot arc. Use compressed air or an appropriate cleaning solution to remove any dirt or residue.
- Check consumables: Regularly inspect the consumables, such as the electrode and nozzle, for wear and damage. Worn-out or damaged consumables can affect the pilot arc quality. Replace them as necessary, following the manufacturer’s guidelines.
- Proper standoff distance: Maintain the correct standoff distance between the torch tip and the workpiece. The ideal distance varies depending on the plasma cutter and the material being cut. Refer to the manufacturer’s recommendations for the specific standoff distance required for your machine.
- Correct amperage setting: Ensure that the plasma cutter is set to the appropriate amperage for the thickness and type of material you are cutting. Using an incorrect amperage can cause instability in the pilot arc. Consult the plasma cutter’s operating manual or seek guidance from the manufacturer for recommended settings.
- Steady motion: Maintain a steady and consistent motion while cutting. Rapid or erratic movements can disrupt the pilot arc, leading to poor cutting performance. Move the torch smoothly along the desired cutting path at an appropriate speed.
- Air supply: Ensure that the air supply to the plasma cutter is clean and free from moisture or oil. Contaminated air can affect the pilot arc and overall cutting quality. Use a properly maintained air filtration system and ensure that the air compressor is supplying sufficient pressure and volume.
- Proper grounding: Make sure that the workpiece and the plasma cutter are properly grounded. A solid electrical connection is essential for a stable pilot arc. Check that the grounding cable is securely connected and that the workpiece surface is clean and free from paint, rust, or other coatings.
By following these tips, you can help maintain a stable and consistent pilot arc on your plasma cutter, resulting in better cutting performance and improved overall results. Remember to always refer to the specific instructions provided by the manufacturer of your plasma cutter for the best practices and recommendations.
