It is a kind of powder feeding device with a plasma welding machine, cladding machine, spray welder. It is used for the surface coating treatment, and strengthening of the workpiece surface of easy-wear parts such as valves, middle groove, shaft plane bore, etc.
The working principle of powder feeder
The powder feeder works on the principle of rotating a powder wheel driven by a motor. The powder is fed to the welding torch through gas assist. By adjusting the speed of the engine, the amount of powder feed can be improved. (Note: Observation through the observation hole, the powder wheel can only be anti-clockwise rotation).
How to use
Electrical connection, make sure the connection is firm and no air leakage. Add soldering powder, screw down the head, then add, screw down the head after adding to prevent air leakage. Turn on the power, rotate the powder feeding speed knob to adjust the speed of powder feeding. Adjust the airflow of powder feeding; the flow is about 5-4L/MIN. Start the powder control button; you can feed the powder work.
The choice of particle size of the welding powder
The granularity of the welding powder is not natural to be too large or too small, 80-300um is appropriate.
Particles too small to send out the powder is easy to blow away, resulting in decreased utilization of the dust.
Particle too large is likely to cause the torch powder feeding channel blocked, resulting in scrap torch.
Solder powder must be filtered by the sieve equipped before adding to avoid the above phenomenon.
Ordering powder feeders from WALDUN
In some cases, we can modify your equipment to incorporate these liner plates when not in the original equipment design. If your equipment has lost some efficiency or does not hold the same tolerances as new, inspect the worn parts. There could be an easy and cost effective fix to the problem.
