10. OPERATION (continued)
(4) 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.
(5) 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.
(6) Setting of Result Display Holding Time: F8
After completion of welding, the average value of output current and output
voltage for last one second blinks for about 20 seconds, but the result
display holding time can be set by F8 using F key [12]. The setting range of
result display holding time is 5 seconds to 60 seconds.
(7) Setting of Feed Motor Load Current Error Detection Level: F10
In the event that contact resistance is applied to the wire feed line section
due to worn liners, defective tips, etc., the current supplied to the motor
increases (when feed roll lacks smooth movement). Monitoring current of
this motor can detect defective feed. The motor load current detection level
at shipment is 70% (2.0A) of the rated motor current 2.8A (continuous), and if
the current exceeds the setting value, "E-" and "820" in the displays are
displayed after welding operation is stopped. But, in this case, the welding
machine stops operation automatically, then it self-restores by re-welding.
This detection level can be changed by changing the setting of F10 using F
selector key [12]. The setting range of motor load current trouble detection
level is 20% to 150%.
NOTE: Adjust the detection level optionally and use it in the best
detection level, because the application environment and judgment
criteria vary depending on wires and torches and customers
respectively.
