to the power source. Make sure that voltage between (1) and (2) of
the control terminal inside the AC ARC welding power source is in the
range of 88V and 90V. If it is less than or more than this range, the
tap of the auxiliary transformer inside the AC ARC welding power
supply should be replaced.
(NOTE) In practice, it is by no means easy to maintain the voltage in
the said range between 88V and 90V. Yet, it is important to maintain
the correct voltage by securing power supply with sufficient capacity in
order to obtain desirable welding results. Next, the control power
switch (LINE) turned "ON".

를 상호 눌러보면서 교류아크용접기의 전류지침이 각기 좌우로 움직이는 것
을 확인하고 적당한 전류치로 세트한다.
이 경우 “+”버튼을 누르고 있다가 급히 “-”로 바꾸는 것을 피하도록 한
다. (전동기의 급속역전으로 인해서 브러시 등이 손상될 위험이 있다.)
* 직류 용접기의 경우 볼륨을 이용해서 조정
By mutually pressing the button switch for current adjustment of the
control box (CONTACTOR), PB3(+) and PB4(-), check if the current
indicator of the AC ARC welder moves left and right. Then set it to an
appropriate value of current. In this process, do not suddenly changed
from the "+" button to the "-" button. (It can damage the brush due to
sudden reversal of the electromotor.)
In the case of a DC welder, it is adjusted by using a volume.
