Depress the F (Function) key for one second or more.
⇒
The setting of internal function completes, and the display returns to a normal state.
6.7.2 Detailed information on internal functions
This section explains the detailed information of internal functions in the order of function No.
6.7.2.1 F1: Standard/Extended cable mode
Sets the the welding control status for extended cables for the application of STANDARD mode. This
function is available when TRAVEL SPEED is set to "STANDARD" and WELDING METHOD is set to
"DC".
Extending the cables at the base metal side/torch side or power cables such as torch cables can cause
extraordinary volume of spatter. When this happens, turning this function ON (extended cable mode)
can improve the status.
• "ON": Extended cable mode
Set to "ON" for the length of extension cable longer than 30 m. The LED of STANDARD starts flashing
when setting to "ON".
• "OFF": Standard mode
TIPS
• In using the welding power source in the "HIGH" mode, the setting of this function is set to
"OFF" and cannot be changed.
• When the status is not improved even by setting of this function to "ON", combined use of
the voltage detection cable is recommended.
When using the voltage detection cable, set the internal function F38 (Arc voltage direct
detection switching) to "ON". (

F38: Arc voltage direct detection switching)
6.7.2.2 F2: Switch of AC start
In the AC pulse welding, to obtain enough penetration at the welding start, DC welding is performed
from the welding start for a certain period. This period is called "DC pulse start period" and it can be set
with F2.
Factory setting is "30" (0.3 sec). Shorten the period in case of controlling the heat input and decreasing
the penetration at the welding start. Lengthen the period in case of increasing the penetration.
Setting range is 0 to 200. The unit of time is 0.01 sec.
AC pulse is performed by setting "0".
⇒
The set value is activated as it is changed.
⇒
Pressing the F (Function) key enables to return the
display to the status described in step 1.
