Semi-Automatic USB Cable Soldering Machine with Automatic Solder Feed WM-712
The WM-712 solders USB cables to plug cores semi-automatically — the operator loads the connector and cable, and the machine runs its four stations of wire clamping, pulling, stripping and soldering in sequence with automatic solder-wire feed. One person keeps output at 300–600 pieces per hour with joint quality that no longer depends on hand skill. The bench unit measures 700 × 420 × 500 mm, weighs 40 kg, and needs only single-phase 220 V power plus 0.4–0.6 MPa compressed air, rated for shop floors from -20 to +50 °C.

Key features
- Four stations in one bench — wire clamping, wire pulling, stripping and soldering run as a single semi-automatic cycle
- Automatic solder-wire feed lays the same amount of solder on every pin, so joints stay uniform across shifts
- Touchscreen in English shows production count and cycle period, with manual and setting modes for quick changeovers
- Compact 40 kg bench format — one operator runs it on 220 V and shop air, no special foundation or fume bench rebuild
What it processes
- USB plug soldering for data and charging cable assembly lines
- Connector-core soldering jobs where hand-iron quality drifts between operators
- Small production cells adding consistent soldering next to cut-and-strip equipment
Suited for: USB cable and connector-core soldering where consistent solder feed and steady pace beat hand irons — data cables, charger leads and small-signal connector assembly. Not suited for: copper-to-copper splice welding — for that, pick the WM-711 ultrasonic wire welder, which bonds 0.75–20 mm² strand splices with no solder at all.
Send 2–3 meters of your cable together with a bag of your USB cores and we run a soldering trial on this machine on video before you commit.

WM-712 — common questions
What does semi-automatic mean on this machine?
The operator places the connector core and cable into the fixture; the machine then clamps, pulls, strips and solders automatically. One person sustains 300–600 pieces per hour depending on the cable and pin count.
What utilities does the WM-712 need?
Single-phase 220 V at 10 A plus clean compressed air at 0.4–0.6 MPa. The bench body is 700 × 420 × 500 mm and 40 kg, and it is rated for ambient temperatures from -20 to +50 °C, so it fits unconditioned workshops.
What can it not do?
It solders — it does not crimp terminals and it is not an ultrasonic welder for copper splices. For crimped connections see the terminal crimping machines, and for strand-to-strand splices see the ultrasonic welders in this category.
