• For optimum fine adjustment:
For fine adjustment of unit pulse condition, first adjust the pulse peak time.
– When large droplet and unstable arc (droplet transfer) occurs, adjust to a longer pulse peak time.
– Adjust to a shorter pulse peak time when tip of wire becomes sharp and extremely strong arc occurs.
For more improvement, adjust the pulse peak current following the same steps as pulse peak time
adjustment.

• Maximum pulse peak current which can be output varies depending on the type
(capability) of welding power source or arc load.
• When the pulse peak current finely adjusted exceeds the maximum pulse peak current,
the preset pulse peak current is not output.
6.7.2.38 F61: Fine adjustment of pulse peak time
This function allows fine adjustment of the standard pulse peak time; by setting the adjustment value,
finely adjusted pulse peak time can be obtained.
Moreover, in the pulse condition of the wave pulse welding at HIGH side, fine adjustment is available
to the standard pulse peak time at HIGH side by setting the adjustment value.

6.7.2.39 F62: Fine adjustment of base current
This function allows fine adjustment of the standard base current; by setting the adjustment value, finely
adjusted base current can be obtained.
Set the adjustment value in the range of -60 to 60 A.

6.7.2.40 F63: Fine adjustment of L pulse peak current
This function allows fine adjustment of the standard pulse peak current at LOW side in the pulse
condition of the wave pulse welding; by setting the adjustment value, finely adjusted pulse peak current
at LOW side can be obtained.
Set the adjustment value in the range of -150 to 150 A.
