10. OPERATION (continued)
(5) For external setting voltage ranges between 0 and 10V: F5
When the welding machine is used by combining with a robot or an automatic
machine and when the maximum command voltage from the robot is output up
to 10V, set F5 using the F key [12]. This function is preset to “OFF” at shipment.
Set F5 and F4 to "on" to activate the function using the F key [12].

The relationship between current/voltage command voltage from outside and
welding current and welding voltage is shown as follows. The welding current
and welding voltage corresponding to welding conditions setting voltage may
differ from the indications in the graphs due to wire extension length and
dragging of output cable. These graphs are only for reference.
Setting Signal 1: When command voltage is externally supplied in the range
from 0V to 15V under the standard se-+ttings.
Setting Signal 2: When command voltage is externally supplied in the range
from 0V to 10V with F 5 set to "on"
NOTE: The current and voltage indicated in the graphs above are not
measured after fine adjustment of unit pulse conditions. You may not
obtain such the results as the graphs show depending on finely
adjustable range of pulse unit conditions.
(6) Setting of Upslope Time: F6*
Upslope time means the time for increasing welding conditions stepwise when
initial current is changed to final current. The upslope time at shipment is set to 0
second, but can be adjusted by using F6. The setting range is 0 second to 10
second. This function is used when wire burns up while conditions are changed
over due to the great difference of setting between initial current and main
current.
(7) Setting of Down-slope Time: F7*
Down-slope time means the time for decreasing welding conditions stepwise
when main current is changed to crater current. The down-slope time at the time
of product shipment is set to 0 second, but can be adjusted by using F7. The
setting range covers 0 second to 10 second. This function is used when wire
crashes into the base metal while the conditions are changed over due to the
great difference of setting between main current and crater current.
