To enable the calibration for the external resistance value, the external resistance value
must be measured. For measurement of the external resistance value under your
operation conditions, refer to " 14 Calibration for External Resistance ".

• Always set the parameter "D1-10" to "disabled" (OFF) at times other than data communi-
cations.
• For aluminum welding, it is recommended to set the parameter for the end event "D1- 4"
to "enabled" (ON) since automatic crater processing is effective. The crater processing
requires approx. two seconds after ARCOF instruction. Set additionally the Timer instruc-
tion so that the manipulator stops for two seconds at the welding end point.
• For synergic voltage, the voltage that Yaskawa assumes adequate is specified as 100%.
Changing the synergic voltage by 10%, voltage varies by approx.about 1V. (Example: In
case of 20V at 100%, it becomes 19V and 21V at 90% and 110%, respectively. The per-
centage (%) can be changed in the range between 50% and 150% (±5V).) The percent-
age (%) that is set at robot synergic voltage is displayed on the welding source in the unit
of V.
• For the welding type: CO

short-circuit arc welding, do not use the touch start but select
the normal start.
• When aluminum welding is selected, the touch start arc becomes enabled (default set-
