How long does it take to make each batch of CS? More ppm takes a longer time.
More ppm requires less current in MA.
Spreading apart the silver wires results in less current and more ppm which also requires more time.
I am curious - what is the current in milliamps being sent to the silver wires? You can put a milliammeter in series with one of the silver wires to monitor the current. Esstee recommends 1 milliamp of current to be optimal for making CS.
