The A151 plasma cutting torch from Trafimet is a handheld air-cooled torch designed for precise and easy metal cutting using plasma generated from ionized air. It works by creating a plasma arc between the electrode and the material being cut, which then melts and blows away the molten metal from the cut groove using a stream of compressed gas.
Construction of the A151 plasma cutting torch
The A151 torch consists of the following components:
- Handle (torch body): Ergonomically designed for ease and precision of operation.
- Cable 4 or 6m: Made from high-quality materials, resistant to wear, weather conditions, and chemicals.
- Electrode and Nozzle: Key consumable parts that wear out during operation and require periodic replacement.
- Connector: Euro-type central plug or 3/8” threaded connector, allowing connection to the power and gas source.
Operation principle of the A151 torch
- Power supply and cooling: The A151 torch is air-cooled.
- Arc ignition: The process begins with the ignition of a high-frequency electric arc (HF).
- Gas ionization: Compressed air flowing through the torch is ionized by this electric arc, creating a plasma arc.
- Stream generation: The plasma is focused into a high thermal energy stream, which is directed onto the material through a suitably shaped nozzle.
- Cutting: The stream of hot plasma melts the material, and the compressed air blows away the molten metal, creating a precise and narrow cutting groove.
Key features
- Type of work: Manual plasma cutting.
- Gas source: Air.
- Maximum cutting current: 150A.
- Power: Powered by electricity, which along with ionized compressed air creates a plasma arc.
To choose the A151 plasma cutting torch (which is the name of the torch type, not a specific model), it is crucial to match it to the parameters of the plasma source (amperage), the thickness of the material being cut, and the type of work, considering work comfort and the availability of consumables. Ensure that the torch is compatible with the power source you have and that its parameters (e.g., current intensity) meet the requirements for the planned material thicknesses.
Key criteria for selecting the A151 torch
- Compatibility with the power source: The torch must be compatible with the type and power of the plasma source it will be used with.
- Thickness of the material being cut: When choosing a torch, consider what thicknesses of material you intend to cut.
- Current intensity: Ensure that the A151 torch is designed to work with the power of the plasma source you need.
- Operating frequency and availability of parts: Pay attention to the availability of spare parts and filters, as well as ease of use.
- Cutting quality: When choosing a torch, ensure that its type allows for high-quality cutting edges, which is essential for precision work.
