5)Here are the operational steps for the F4MB-XL Plasma Spray Gun (concise English version):


1. Pre-Operation Setup:

Inspect gun components (anode, cathode, gas lines) for wear/damage.
Connect gas supply (Ar/He/H mixture) and cooling water (12 L/min flow).
Load feedstock (powder/wire) into the feeder and calibrate feed rate.
2. System Activation:

Power on the control unit (50-100 kW range).
Initiate gas flow (adjust ratios via console) and ignite plasma arc.
Stabilize temperature (~16,000°C) and particle velocity (~450 m/s).
3. Spraying Process:

Position gun 100-150 mm from the substrate.
Trigger robotic arm (or manual operation) for uniform passes.
Monitor coating thickness in real-time (target porosity <2%).
4. Shutdown & Maintenance:

Gradually reduce power and gas flow.
Purge the system with inert gas to prevent oxidation.
Clean nozzle and electrodes; log operational hours.
Safety Note: Always wear heat-resistant PPE and ensure proper ventilation.


6)High performance F4 plasma nozzle(anode) and F4 electrode(cathode)
In the plasma spraying process, metal or ceramic powder is melted in a plasma arc and then sprayed at high speed onto the workpiece to be coated. In this way, water-impermeable, highly adhesive coatings can be deposited on tools and various equipment components. When used in spray guns, our electrodes must be able to withstand transient plasma temperatures in excess of 12,000°C. This kind of instantaneous high temperature and pressure is not a problem for our F4 electrode. Our company uses back-casting production technology to form a seamless connection between tungsten and copper, which is extremely strong. Therefore, our electrodes can provide stable working conditions for a long time and extend their service life.
Different from the brazing method, brazing uses solder as an intermediate medium to fuse the two alloys, but it is difficult to achieve 100% connection. Therefore, the product produced in this way is first of all not strong enough and is not suitable for the extreme conditions faced in the gun body. High pressure and high temperature can easily cause uneven heat conduction and cracks.
