rotate the knob with the beginning of 0 (0 means there have
no arc force), and when slowly clockwise rotate the knob,
the digital will grow bigger, the maximum display is "50".
Function
switch ( The current of arc force =real current+ 50% real current).
The display "50" means that at this time, you have choosen
a 160Amp Arc Force,the maximun current for the arc force
is 160Amp, Default is 30%.
Fourth time: Anti stick. The display code is "AnS". Clockwist
rotate the knob, will display "ON". Anticlockwise rotate
the knob, will display "OFF". Default is "ON".
