Why do you need pilot arc in plasma cutter?
Feb 07, 2024
Pilot arc and ordinary plasma cutting are two techniques used in the process of plasma cutting, a method that uses a high-velocity jet of ionized gas to cut through electrically conductive materials. Let's explore both concepts:
1. Ordinary Plasma Cutting:
ย In ordinary plasma cutting, a high-frequency electrical arc is used to ionize the gas, typically compressed air, creating a plasma state.
ย The plasma jet generated is then directed toward the workpiece, and the high-temperature plasma melts the material and blows away the molten metal, resulting in a clean and precise cut.
ย This method is effective for cutting a variety of materials, including steel, aluminum, copper, and other conductive metals.
ย
2. Pilot Arc Plasma Cutting:
ย Pilot arc plasma cutting uses a different approach in terms of initiating the plasma arc.
ย Instead of directly touching the workpiece with the electrode to create the arc, a pilot arc is established first, independent of the workpiece.
ย The pilot arc is a low-current, high-voltage discharge that forms between the electrode and a nozzle. This arc ionizes the gas, creating the plasma state.
ย Once the pilot arc is established, it can be transferred to the workpiece by bringing the electrode in contact with the material. This allows for a stable and continuous cutting process.

| Arc Initiation | by bringing the electrode in direct contact with the workpiece. | initiates a low-current, high-voltage pilot arc independent of the workpiece. |
| Electrode Wear | This direct contact can cause wear and tear on the electrode, leading to shorter consumable life. | This can result in a longer lifespan for consumables. |
| Application and Material Considerations | suitable for a wide range of applications and materials, especially when a direct contact arc initiation is not a limitation. | preferred when cutting painted or coated materials, perforated metals, or in situations where maintaining an arc on the workpiece may be challenging. |
| Cost and Complexity | simpler and may be less expensive. | often more complex and can be more expensive. |
| Versatility | versatile and suitable for various applications, making them common in many metal cutting scenarios. | versatile as well and may be chosen for specific applications where the benefits of a pilot arc, such as extended consumable life and improved arc stability, are crucial. |
