The A-81 plasma cutting torch, also known as LT-81, is a popular air-cooled handheld plasma torch for cutting metals of small and medium thickness, with a power of up to about 80A, characterized by a simple design and low operating costs.
Construction of the A81 torch:
- Torch with gas nozzle and electrode.
- Air cooling: The torch is air-cooled, allowing for effective operation.
- Control plug: used to connect control signals and pilot voltage to the plasma cutter.
- Ergonomic handle: Provides comfortable and effective operation.
- Cable: The standard cable length is 6 meters, providing freedom of movement.
- Simplicity of design: The design of the torch is simple, which contributes to low operating costs.
Purpose of the A81 plasma cutting torch:
- Plasma cutting: The torch is used for manual plasma cutting of metals.
- Material thickness: Ideal for cutting elements of small and medium thickness, including light steel structures and steel plates up to about 15 mm thick.
- Type of cutters: Used in plasma cutters with cutting current up to 80A, such as Welder Fantasy HERTY II 60 and HEFTY II 80.
- Equivalent to Trafimet ERGO CUT-81: It is a replacement for the torch from Trafimet, a popular and respected manufacturer.
When choosing the A81 plasma cutting torch, check compatibility with your plasma source, considering the cutting current and connection method, and select the torch according to the type of material being cut and its thickness. It is important to verify that the A81 torch is intended for use with your specific plasma cutter model.
Key criteria for selecting the A81 torch:
- Compatibility with the power source: Cutter model: First of all, ensure that the A81 torch is designed to work with your plasma cutter model.
- Cutting current: Check what cutting current (amperage) is supported by the A81 torch and compare it with the power of your cutter.
- Connection method: Pay attention to the type of torch cable connector, as it must fit the socket on your cutter.
- Type and thickness of the material being cut: Material: A81 torches are usually intended for cutting specific materials (e.g., aluminum, steel), which affects the choice of the appropriate torch.
- Thickness: Choose a torch suitable for the maximum thickness of the material you will be cutting. Torches are designed for various thickness ranges.
Additional factors:
- Working gas: Ensure that the torch is suitable for use with the gas you intend to use (e.g., air, nitrogen, argon).
- Torch height: The A81 torch has a specified distance from the workpiece that must be considered during operation.
In summary, before purchasing the A81 torch, check if it is compatible with your plasma cutter system in terms of technical parameters and suitability for specific materials.
