Budget Induction Forge

Description

This is my cheap induction forge based on the ZVS2000S 2 kW induction-heater driver board, a Eltek Flatpack 2 (2000w) BF PSU and a LianLi Gallahad aio radiator, all jammed into an old camera case.

I chose that particular ZVS board as whilst still being quite cheap it comes with some nice features like various protections, pads to hook up an external switch and the LCD actually provides useful info. It's pushing the limits of the FP2 PSU, but for work-pieces that match the coil well it's enough to get them to a good workable colour. The FP2 was chosen as it's also very affordable and very well regarded as a quality PSU, there are well documented projects allowing control of it's various parameters via its CAN bus. The next addition to the forge will be adding a CYD to control the FP2.

Total cost if you have any kind of case and an old AIO/rad is under £100.

Work in progress!

This was assembled in a rush from stuff I had laying around as I just wanted to get forging.

Next up is:
- Add and wire up the missing fan
- Tidy up internal wiring
- Hose clamps!
- Sort out the reservoir - add external overflow/venting and fill port, ditch the electrical tape!
- Label the external connections (12v in and the foot switch use the same connectors)
- CYD - add FP2 control and monitoring
Planned future upgrades
- Better case
- Check the debug ports on the ZVS board - if serial out use this to build a nice UI combined with the FP2 info
- Interchangeable coils
