*1: The duty cycle (load time for a period of 10 minutes) of “JIS C9300-1 3.37” is not adopted.
*2: This product is dedicated to argon gas. When the initial current and base current of pulse
current and modulation is set lower than 15 A and the flow rate of argon gas is higher than 1
L/min, a misfire may occur. Adjust the flow rate of argon gas according to the welding
conditions to use.
*3: This welding machine is classified as Class A in electromagnetic compatibility (EMC) based on
CISPR11. The Class A equipment is intended for use in industrial environments and not
intended for use in general households.
*4: Use this product in the environment without conductive dust. If conductive dust enters in the
product, this may result in a failure, electric shock, or fire. When using this product in this
environment, make contact with us.
*5: WELD1 + CWELD2
≤
4000 ms
*6: Our specified torch and workpieces should be used as a condition. Full scale is 50 A.
*7: Internal timer and OR operation. Regarding internal timer control, the ON/OFF of the function
can be set.
*8: The count value is displayed for 6 seconds after the emergency stop signal is reset. In this
period, only the reset signal or reset button can be operated.
*9: In 0-ms setting of the initial current time, the auto mode is selected when the fine weld mode
setting is OFF, and the fine weld mode is selected when the fine weld mode setting is ON.
*10: For welding very small workpieces in the fine weld mode, the initial current and the first up-slope
can be set from 1 A. However, if a misfire occurs with 1-A setting due to the welding conditions,
increase the current setting from 1 A gradually.
*11: The modulation base current can be set from 1 A. However, if a misfire occurs with 1-A setting
due to the welding conditions, increase the current setting from 1 A gradually.
