Highlights




Only brand-new supercapacitors
No refurbished or imported salvaged capacitors — brand-new automotive-grade supercapacitors run at rated voltage for double safety and stability.

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.

15A high-current fast charge
The supercapacitor recharges in seconds, so continuous welding never waits or fades.

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.

Weldable thickness (mm, MAX)
Lab maximums; results vary by material and environment.See all nine spec groups ›
