300A plasma bore welding gun consists of three parts: upper gun body, lower gun body and insulator. The upper gun body is used to fix and install the tungsten electrode and connect the water and electric joints; the lower gun body fixes and installs the nozzle and constitutes the water-cooled cavity of the nozzle and connects the joints of the water, electric, gas and powder pipelines; the insulator ensures the insulation of the upper and lower gun bodies and connects the fixing of the upper and lower gun bodies. The protective gas of the gun body completes the gas diffusion inside the gun body to form a uniform protection.
❓ Frequently Asked Questions (FAQ)
1. What are the main components of the 300A plasma bore welding torch?
The torch consists of three primary parts: the upper gun body (for tungsten electrode and water/electric joints), the lower gun body (for nozzle and pipelines), and the insulator which ensures insulation between the two bodies.
2. What is the current range and tungsten pole size for this model?
This welding torch operates within a current range of 50-300A and utilizes a 4.8mm tungsten pole.
3. How is the cooling system designed for the copper nozzle?
The copper nozzle uses a direct water cooling method. It features a water-cooled cavity and requires a return water flow of approximately 3.2L/Min for efficient operation.
4. What are the gas flow requirements for ionized and protective gases?
The ionized gas flow should be between 1.0-4.0L/min, while the protective gas flow ranges from 5-20L/min to ensure uniform protection.
5. What type of powder feeding capacity does this torch support?
The torch has a powder feeding capacity of 0-3KG/h and supports both two-way and four-way powder runners within the copper nozzle.
6. What is the recommended granularity for the powder used?
The recommended granularity for materials used with this 300A plasma bore welding torch is between 100-270 mesh.
