Migatronic CWF Multi PI 320 Betriebsanleitung Seite 10

Stop delay
At the beginning of the slope-down period,
the welding machine informs the CWF about
the need for stopping the wire in order to avoid
sticking problems. If the slope-down period is equal to
zero, the delay is not executed.
Variable 0-10 sec.
Retract time
The time in which the wire is retracted after
end of welding process. Variable 0-5 sec.
Retract speed
The speed of which the wire is retracted
after end of welding process.
Variable 0.2-5 m/min.
ON/OFF
This key pad is used to enable/disable the
CWF. When the unit is disabled, the display
shows "OFF" and the green light on the keypad will be
turned off. Some operations can only be carried out
when the unit is disabled.
Flashing light will indicate:
- no CWF units have been configured on PI
- possible communications problem
synchronised with pulsation of current on the arc: in
this case the LED is flashing. See below.
The values of speeds are fully independent, permitting
the generation of "reversed" pulses: high speed at low
currents and vice versa.
Main speed pulse time:
The time for which the wire runs at main
speed. If the welding machine has been set
to slow pulse mode, the value of the parameter cannot
be controlled and will be the same as the one on the
welding machine. Variable 0.2-10 sec.
nd
2 speed pulse time:
The time for which the wire runs at 2
If the welding machine has been set to slow
pulse mode, the value of the parameter cannot be
controlled and will be the same as the one on the
welding machine. Variable 0.2-10 sec.
