AWithZ HF7
First handheld supercapacitor welder
Supercapacitor in a pen: 1060A peak, 1.5M cycles, 10-second recharge, welds 0.3mm nickel/copper — the most capable handheld in its class.

Details
Only brand-new supercapacitors
No refurbished or imported salvaged capacitors — brand-new automotive-grade supercapacitors run at rated voltage for double safety and stability.
Low-ESR · 1060A · 1.5M cycles
A full-electrode low-ESR design unleashes stronger welding current; an in-house dynamic algorithm handles auto-stop charging, health monitoring and balancing — equivalent to 1.5M-cycle life.
Powerful dual-pulse
The first pulse breaks the oxide layer, the second precisely controls temperature and melt; dual-pulse scheduling balances weld strength and quality.
Thousands of settings · six core parameters
Mode (manual/auto) · level · preheat · interval · trigger time · repeat — six dimensions combine into tens of thousands of output profiles, so thin sheets don't burn through and thick stock doesn't cold-weld.
OLED full-color control console
Level / trigger / interval / preheat / repeat / mode — six variables adjusted in real time, effortless at your fingertips.
Dual-head precision pins
One pin, two tips: the fine end welds thin material precisely without piercing, the thick end welds thick material through and solid — and it's wear-resistant for longer life.
Engineered pin-change system
Rail + embedded mounting swaps pins in 5 seconds, with 0.5–3mm stepless spacing and 360° secure locking — no more misaligned, loose, spark-prone threaded pins.
MT/AT dual-mode control
Manual precise triggering plus one-touch auto welding — batch work and precision in one.
8-layer safety protection
Quality cells/capacitors · shock · voltage · short-circuit · low-temp · high-temp · overcharge · over-discharge protection; a built-in safety chip, thermal sensor and safety algorithm give hardware-plus-software protection.
Plug in and go, no waiting
Type-C 12–20V input, full charge/recharge in 10 seconds — never worry about power.
