Induction Brass Annealing Machine

Projects General Guidance
1

Hello, I am in the planning process of the project of the induction brass annealing machine. I have ordered Mini Induction Heater https://www.rmcybernetics.com/files/pdf/CRO-SM2.pdf and now I am looking how to connect this device with my Arduino Uno.

In the manual mentioned above I am interested in Special Mode = NO_LD_SHDN No Load Shutdown
SET CURRENT MODE
With the power output running, briefly pulling
this pin low will save the current power state as
the minimum acceptable load. The value is
stored in non-volatile memory and will function
even after the circuit has been powered off and
on again.
If the measured current falls approximately
0.5A below this value, the power output will be
disabled until the current is high enough again.
Roughly every second, the coil will be pulsed
to measure the current.
To reset this value to zero, this input should be
pulled low when the output state has been
manually disabled.
NB: This mode will not work while the device is
in other special modes such as power
modulating or using the ADC

My question is can I do it with Arduino or I should just short that solder path to GND?

All help is welcome

You quoted from something about your machine, but you did not state WHAT the Arduino is supposed to do! What is the voltage on the pin that you want to pull to ground and is it positive or negative

well, according to this, https://www.rmcybernetics.com/files/pdf/CRO-SM2.pdf, the pin is a logic pin (3.3v-5.0v=HIGH, LOW unspecified so assume 0v to 0.5v) so you can pull it low with an arduino (which shares a common ground with your device).

But, before you start, you should have a plan of how you integrate this device with an Arduino and what role the Arduino should have. (as already mentioned)
