Rated duty cycle X=100% means take 10min as a circle, machine can work 10min, that means machine can 24 hours work
without stop. The machine working is under temperature -10
℃～
+40
℃，
if ambient temperature over 40
℃
or too much dust
inside the machine will cause the duty cycle reduce, maybe the machine will be burnt.
3.4
Overheat protection
This machine adopt temperature relay for heat protection, if machine work over the rated duty cycle or ambient
temperature over 40
℃
cause machine over heat, the temperature relay will stop the machine to avoid burnt.
Machine can continue to work when the inside temperature turn to normal and the overheat indicator off.

AC frequency
（
）
indicator: it will be on when ammeter show AC frequency(Hz), can adjust the AC frequency
parameter by turn the knob.
10.
Wave balance
（
）
indicator: it will be on when ammeter show the wave balance(%), can adjust the wave
balance parameter by turn the knob.
11.
DC deposition
（
）
indicator: it will be on when ammeter show the DC deposition (%), can adjust the DC
deposition parameter by turn the knob.
AC frequency, wave balance and DC deposition indicator select by the parameter adjust knob, 3s after adjustment finish,
