HF7 launch: a supercapacitor in a pen-shaped body
1060A peak current, 1.5M cycles, plug-in with 10s recharge, solid welds on 0.3mm copper-nickel.
HF7 is AWithZ's 2025 industry-first handheld supercapacitor welder.
An automotive-grade supercapacitor with a full-electrode low-ESR design delivers 2000W instantaneous current; an OLED full-color "console" carries thousands of fine settings, with replaceable dual-head pins, an engineered pin-change system, MT/AT dual mode and an 8-layer safety shield.
Ideal for power-tool and appliance battery maintenance, battery making and repair, electronic cell replacement, model DIY and light metalwork.
Highlights
No refurbished or imported salvaged capacitors — brand-new automotive-grade supercapacitors run at rated voltage for double safety and stability.
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.
The first pulse breaks the oxide layer, the second precisely controls temperature and melt; dual-pulse scheduling balances weld strength and quality.
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.
How thick can it weld
Lab maximums; results vary with material batch and conditions, so test on scrap first.
Putting everything into every welder, so it is worthy of the people who use it — that is AWithZ's baseline.
