Hi all, I have k40 with digital power,

Hi all, I have k40 with digital power, Hou much percent I can use for don’t pass safe current? And big thx for answer.

50% on your machine will not be the same on my machine.

Buy a 30mA ampeter meter to see what your machine operates at.
Mine reaches max at 65%, your maybe do it at 50, or 82, only safe solution is to measure it.

anybody know what brand of the China 40Watt is good ?
and recommend a good site ?

Big thx, but in my country I don’t found to little ammeter, is over 1 amp, I will buy a digital ammeter I think.
