Yellow-handled self-adjusting wire stripper with integrated voltage detector and crimping jaws

KEHIPI

KEHIPI TWS-322 4-in-1 Electrician Tool 10-24 AWG NCV 70-250 V

SKU CH-WCXT-PZ0Z6 MPN TWS-322

Self-adjusting stripper handles 10-24 AWG wires with built-in 70-250 V non-contact voltage detection, cutting and crimping in one tool

  • NCV detects live AC circuits 70-250 V with audible and visual alarm
  • Self-adjusting jaws strip 10-24 AWG solid, stranded and sheathed cables without manual hole selection
  • Adjustable stop sets precise strip length; thumbwheel tensioner prevents core damage on small gauges
  • Integrated cutter handles copper, aluminium and sheathed core wires in one tool
  • Built-in crimper terminates insulated and non-insulated terminals for complete 4-in-1 workflow

What the tool does and who uses it

The KEHIPI TWS-322 combines non-contact voltage detection, self-adjusting wire stripping, cutting and terminal crimping in one hand tool. It works on cables from 10 to 24 AWG and alerts the user with sound and a red light when AC voltage between 70 and 250 V is present. Electricians, maintenance technicians and DIY installers who want a single device for live-circuit checks and wire preparation will find it useful.

Practical limits of the detection

The NCV function only indicates the presence of alternating current in the 70 to 250 V band; it does not measure exact voltage, polarity or direct current. Stripping performance is confined to the 10 to 24 AWG window, so thicker power cables or finer data wires fall outside the self-adjusting mechanism. The tool cannot replace a multimeter for verification or a dedicated crimper for high-volume production terminals.

Installation ease and common issues

No setup is required beyond selecting the length stop for fixed or mid-span strips and turning the tension thumbwheel toward "+" if the wire slips or "-" if the conductor is being scored. The most frequent problem is over-tightening the strip-force nut, which damages fine strands, or leaving the stop block flipped down when a precise end strip is needed. Periodic cleaning of the jaw teeth keeps the self-adjusting action reliable.

Questions about this item

Which AWG range should I choose for typical household wiring?

The tool automatically adjusts from 10 to 24 AWG, covering most residential solid and stranded cables without changing settings.

What does the 70-250 V detection range mean on a live circuit?

It alerts with sound and red light when AC voltage between 70 and 250 V is present near the tip, letting you confirm a circuit is live before stripping.

How does the non-contact voltage detection interface work in practice?

Hold the detector near a conductor; if voltage in the 70-250 V range is sensed, an audible alarm and red LED activate instantly.
