3.11 Welding conditions of WB-P350L/P400L/P500L
3-40
Concerning the pulse conditions
To adjust the pulse conditions, proceed by changing “arc characteristic” and “pulse frequency”,
described inTable 3.11.1 And refer to “3.11.4 To adjust the pulse conditions”
Concerning the retract adjustment time
The wire is automatically retracted in order to adjust its protrusion length after processing the
arc end. By setting the retract adjustment time, it enables to adjust the amount of wire
retracting after the arc end.
The retract time before adjustment depends on the type of wire feeding unit as given in Table
3.11.2. Even if setting the retract time to a negative value, the retract time becomes 0, in which
the wire cannot be inched.
Table 3.11.2 Retract time before adjustment
Wire feeding unit Retract time (msec)
Standard wire feeding unit 200
Servo wire feeding unit 100
When the registered welding power source is DP, it is not available to set the
retract adjustment time. Retracting is executed for the time specified in the
Table 3.11.2 as the adjustment time of 0.
