What are the Components & Processes of a Plasma Cutter?
- Power Source: The power source provides the electrical energy necessary to create the plasma arc.
- Plasma Torch: The plasma torch houses the electrode and nozzle and is the device through which the plasma arc is created and directed.
- Electrode: The electrode is a conductive metal rod that protrudes from the plasma torch and makes contact with the workpiece.
- Nozzle: The nozzle is a small copper cone located at the tip of the plasma torch. It helps to focus and direct the plasma arc.
- Shield Cup: The shield cup is a metal cup that surrounds the electrode and nozzle. It helps to protect them from arcing and damage.
In order to create the plasma arc, the power source must provide enough electrical energy to ionize the gas within the plasma torch.
This process begins with the electrode, which protrudes from the plasma torch and makes contact with the workpiece.
When the electrical current flows through the electrode, it heats up the gas within the torch, causing it to ionize.
The ions are then drawn towards the nozzle, where they are focused into a small, intense plasma arc. The shield cup helps to protect the electrode and nozzle from damage by surrounding them with a metal cup.
