..back to development of the chassis for the high-voltage flux supply. The refinement pen already has a first iteration and design improvements to be implemented.
There is a new copper tube flux emitter design, the original solid copper core wire would have been bent and eventually needed replacement. The copper tube version is much more solid, though remains untested ..either way, the device is well within a safe range for wattage at 52 Watts. If need be, 104 watts is still a reasonable power consumption to expose the operator to (worst case scenario).
The device needs to be solid and reliable for many years, while designed for repair and reuse. There will be no returns for the first devices. As they were hand-built by one person, there is currently no infrastructure to handle customer relations and good return policy.
The sale will necessarily include a disclaimer and agreement for those who are willing to forego the after-sale service in favor of having the device.
