2UUL DA20 Electric Wire Wrapping Bar

Picture a technician separating a cracked front glass from an OLED panel with cutting wire. Holding the wire taut with both hands while it slices through the adhesive is slow, and the slack wire gets tangled. A bar that winds the wire as it goes keeps it tight and the job moving.

The 2UUL DA20 is an electric bar for winding screen-separation wire. Retailers describe it as having adjustable winding speed and automatic wire feed. They also say it doesn't damage the polariser film, which makes it safer on curved screens. The listing text for this product was mixed up with a blade set and generic wire-wrapping copy, so it's been rewritten here from those retailer listings.

When it saves time

• Cracked glass that needs separating from an OLED or LCD panel.

• Tangled or loose wire during manual separation.

• Damage to the polariser film from uneven wire tension.

• Curved screens where hand-held wire is hard to control.

Practical notes

Use the DA20 with the separation wire you normally use. Start with a low winding speed, and increase it once the cut is running smoothly.

Pre-heating the panel on a separator softens the adhesive and reduces strain on the wire.
