When I need to buy expensive mechanical or electrical tools, I often check for faulty units available for sale that I can repair, which helps me save a significant amount of money. Recently, I needed an oxygen generator for my jewellery soldering system, as purchasing compressed Oxygen in cylinders is quite costly. I bought a faulty AirSep VisionAire 5 oxygen concentrator for £50, which retails for around £1,000 new.

The issue with this unit was that it would shut off after five minutes of use and emit a series of four beeps, indicating a high-pressure fault. After conducting some research online, I discovered that over thirty other people had encountered the same problem, and no one had provided a solution.

Upon inspecting the unit, I identified the problem and found a solution, which I now share with those looking for a quick fix for the high-pressure beeping issue in these units.

Check out my video, which demonstrates the issue and provides a quick-fix solution.
