(2) If the 7-segment LED indicators of "A" and "Wire" on the panel blink, the current cal-
ibration 2 is in standby state.
(3) Set the welding current command to be calibrated from the robot controller side, and
perform welding for six seconds or more.
(4) The calibration performs arithmetic operation for the ratio of the welding current
command to the actual welding current value based on the welding current value
after two to six seconds from welding start.
(5) The LED indicator lamp above the "Record" button flashes when the calibration
operation is confirmed.

Confirming the result of calibration 2
(1) Keep pressing the "R" button to confirm the result of current calibration 2.
Set the welding current command value so that the command value of the current calibra-
tion 2 is higher than that of the current calibration 1.
If the welding time is less than six seconds, the LED indicator lamp above the "Record"
button does not flash after welding. Perform welding for a longer time and welding current
calibration again.
