6.7.2.22 F38: Arc voltage direct detection switching
Sets the status of the voltage direct detection terminal on the base metal side of the welding power source
or voltage detection terminal of the wire feeder.
Extending the power cable without the cable at the base metal side can cause extraordinary volume of
spatter. In this case, turning ON this function by using the voltage detection cable (optionally available)
can improve the status.
Connection of voltage detection cable (optionally available) ( 4.6
-
Wiring of Voltage Detection Cable at
Base Metal Side)
• [ON]: enables the function.
Arc voltage can be detected by the voltage direct detection terminal at the base metal side/voltage direct
terminal.
• [OFF]: disables the function.
T I P S
• Use the voltage detection cable (optionally available) when the total length of the extension
cable is 1181.1" (30 m) or longer.
• When using water-cooled welding torch, voltage detection cable (optionally available)
cannot be used. Accordingly, arc voltage direct detection switch cannot be activated even
with this function set to "ON".
6.7.2.23 F39/F40: Current display adjustment (Gain/offset)
Set the adjustment value (gain/offset) when the current display value on the left digital meter is different
from the actual current value.
The current value displayed on the digital meter is obtained by software processing of the average value
of outputs; therefore, it may not be consistent with the value indicated on a needle meter, etc. When this
happens, using this function enables to finely adjust the current display value.
• For F39, set gain, and for F40, set offset.
Changing the set value only corrects the display; the output welding current does not change.
• For more information on the adjustment procedure, contact dealer.
NOTE
• Do not carelessly change the setting of this function.
6.7.2.24 F41/F42: Voltage display adjustment (Gain/offset)
Set the adjustment value (gain/offset) when the voltage display value on the right digital meter is
different from the actual voltage value.
The voltage value displayed on the digital meter is obtained by software processing of the average value
of outputs; therefore, it may not be consistent with the value indicated on a needle meter, etc. When this
happens, using this function enables to finely adjust the voltage display value.
• For F41, set gain, and for F42, set offset.
Changing the set value only corrects the display; the output welding voltage does not change.
• For more information on the adjustment procedure, contact dealer.
