7 Troubleshooting

Fault
The wire cannot be
run-in
Wire feed during the
welding process is
irregular or stops
Page 62 / 63
Possible causes
The drive is closed u for wire run-in
The welding wire has not been carefully de-
burred and straightened before it was fed
into the cable assembly
Welding wire protrudes from the side of the
drive unit
The torch neck and cable assembly are not
suitably equipped for the wire diameter and
wire material
The liner nipple (102) on the torch neck is not
selected for the wire diameter
The wire guide is not correctly and fully
inserted into the assembly cable
Wire coil is empty
Too much friction in the cable assembly, the
contact tip or the wire guide is showing
abrasion or wear.
Unsuitable control of the Push-Pull motor or
cable break in the control cable.
Measures
Open cover (4). Open drive unit by unlocking
the tension spring holder (14) and opening
the pressure roll holder (20).
Pull out the welding wire again, trim the end
of burrs and straighten the first 10cm of the
wire. Then re-thread into the cable assembly.
If necessary, pull a bit of the welding wire
back into the feed unit and feed the welding
wire end into the liner nipple (102) in the
torch neck (see Section 4.3).
Check the wire guide (in the torch neck and
cable assembly), liner nipple and contact tip.
Screw correct liner nipple into the torch neck.
Check the correct positioning of the wire
guide through the viewing window (13).
(see Section 3.3.6). If no wire guide can be
seen in the window, the wire guide has not
been fully inserted. If necessary, make
inserting easier by turning the wire guide
between fingers.
Check the amount of welding wire on the coil
in the welding machine or wire feeder.
Check contact tip, liner nipple (102) and/or
wire guide, renew if necessary. Blow
compressed air through torch neck, drive
unit, wire guide channel and wire guide.
Check for correct electrical connection.
Adjust the characteristic curve correctly when
using a Push-Pull control module or the TBi
Syntronic.
If the problem occurs from the very start, the
TBi control board may have to be switched to
another connection type.
