| Problem |
Possible Cause |
Possible solution |
| Conductors cut |
Conductor diameter setting too small |
Increase the conductor diameter setting (see section 6.5) |
| Wire not cut through |
Dull blades or conductor is too heavy for the cutting head |
Change blades or/and decrease the cut rate (see section 6.7) |
| Both ends slugs not pulling off |
Blades do not cut insulation |
- Inspect blades alignment (See section 7.2)
- Inspect blades integrity. If they have broken, dull cutting edges, change them (See section 7.2)
- Decrease the conductor diameter setting (see section 6.5)
|
| Too much releasing during the pull |
Decrease the release blade setting ( see section 6.8) |
| Conductors scraped |
Release Blade Setting too small |
Increase the release blade setting ( see section 6.8) |
| Conductor diameter setting too small |
Increase the conductor diameter setting (see section 6.5) |
| Right strip slug not pulling correctly |
Pull length not set correctly |
Set strip and pull length to the correct values (See section 6.6) |
| Wire slipping in left belt feeder |
Tighten left feed belts (See section 5.3) |
| Left strip slug not pulling correctly |
Pull length not set correctly |
Set strip and pull length to the correct values (See section 6.6) |
| Wire slipping in right belt feeder |
Tighten Right feed belts (See section 5.3) |
| Right strip bent back when exiting the machine |
Strip hits a right feeder belts |
Use a Wire Straightener (AR3950) |
| Too much conductor exposed |
- Leave the insulation slug on the wire (semi-strip)
- Decrease the right pull (see section 6.6)
- If the process calls for a long strip and a short strip, put the long strip on the left end.
|
| Small gauge Teflon wire not stripping |
Dull cutting blades |
Inspect cutting blades, if dull replace (See section 7.2) |
| Blades out of alignment |
- Align the cutting blades (see section 7.2)
- Use different combinations of blade and blade release settings
|
| Wire lengths not accurate |
Wire slipping in left feed belts |
Tighten left feed belts (See section 5.3) to prevent slippage |
| Too much friction on dereeling system |
Readjust dereeling system to prevent tugging on the reel |
| Wire Straightener too tight |
- Reduce the Wire Straightener tension (AR3950)
- Check feed rate, slower speed have greater torque which result in better accuracy
|
| Feed belts stall when trying to feed wire |
Wire Straightener too tight |
Reduce the Wire Straightener tension (AR3950) |
| Too much friction on dereeling system |
- Readjust dereeling system to prevent tugging on the reel
- Decrease the feed belts pressure
- Check feed wire speed, slower speed have greater torque which result in better accuracy
|
| Wire hits blade and jams |
End of the wire deviates widely from the center line |
- Use a Wire Straightener (AR3950)
- Install the next smallest bushing (See section 5.1)
- Check bushing alignment
- Decrease the feed rate
|
| Left wire end hits input bushing and jams |
Left wire end of the wire deviates widely from the center line |
- Use a Wire Straightener (AR3950)
- Install the next smallest wire output bushing (See section 5.1)
- Check input bushing alignment
- Decrease the feed rate
- Force the input bushing to lift up
|
| Right wire end hits output bushing and jams |
Right wire end of the wire deviates widely from the center line |
- Use a Wire Straightener (AR3950)
- Install the next smallest input bushing (See section 5.1)
- Check output wire guide alignment
- Decrease the feed rate

| Unit Overheats |
Clogged fan filter |
Remove fan filters, clean (See section 7.3) |
| Ambient Temperature to high |
Refer to Section 2 (Operating Environment). Also, see Section 3. |
