Wire Feed - Fronius ROB 4000 TIG Bedienungsanleitung

Wire feed

Risk of injury from filler wire emerging.
This can result in serious injury and damage to property.
▶
Signal X2:7
The „Wire inching" signal enables the filler wire to be fed into the hosepack without the
use of current or gas (as does the „Feeder inching" key).
The feeder inching speed is determined by the corresponding setting in the power
source setup menu.
NOTE!
The „wire feed" input signal has priority over the „wire retract" signal. If both
signals are present at the same time, the wire feed continues.
IMPORTANT! To facilitate the exact positioning of the filler wire, the following procedure
is executed when the „wire inching" signal is set:
Fdi
Time-path of the wire speed when the digital input
signal „Wire inching" is set
IMPORTANT! If the digital input signal „Cold wire disable" is also set, then the analog
output signal „wire speed" applies, rather than „Fdi". The digital input signal „wire inching"
starts immediately with the analog command value for the wire speed. In this case, the
figure does not apply.
