6.7.2.25 F35: Saving [Squeeze] detection sensitivity
Sets whether to return the sensitivity corrected by F34 (Automatic correction of [Squeeze] detection sensitivity) to the
initial value when welding completes or maintain it after welding completes.
•
[ON]: uses the detection sensitivity at the welding completion also at the start of next welding.
(When the condition at the welding completion and the one at the start of next welding are significantly different,
there may be much spatter at the start of welding.)
•
[OFF]: Returns the detection sensitivity at the welding completion to the initial value.
If there is much spatter at welding start, adjust the initial value in the following step:
1.
Set the internal functions F36/F37 (Spatter adjustment).
(

-
F36/F37: Spatter adjustment (P1P/P2P)”)
2.
Set the internal function F34 (Automatic correction of [Squeeze] detection sensitivity) to ON.
T I P S
• If wire extension and welding conditions greatly vary by welding section, it is recommended to use the
machine with this function set to [OFF].
6.7.2.26 F36/F37: Spatter adjustment (P1P/P2P)
Use this function to manually set the detection sensitivity of [Squeeze]. This function is available when the internal
function F34 (Automatic correction of [Squeeze] detection sensitivity) is set to [OFF].
Follow the step below for setting the adjustment.
1.
Set the internal function F34 (Automatic correction of [Squeeze] detection sensitivity) to OFF.
2.
Display the internal function F36 (Spatter adjustment (P1P)), and carry out the welding with F36 displayed.
3.
Increase or decrease the setting value of internal function F36, and carry out the welding again.
●
Repeat this step until the good condition of welding is obtained, by adjusting the set value in the range of -100 to
100.
4.
Display the internal function F37 (Spatter adjustment (P2P)), and carry out the welding with F37 displayed.
5.
Increase or decrease the setting value of internal function F37, and carry out the welding again.
●
As in the step 3, repeat the step until good condition is obtained, by adjusting the set value in the range of -100 to
100.
6.7.2.27 F38: Arc voltage direct detection switching
Sets the combination of enabling or disabling the voltage direct detection terminal on the base metal side of the welding
power source and 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,
setting this function to "1" by using the voltage detection cable (optionally available) can improve the status.
