Details
Only brand-new Grade-A cells
No high-drain, risky B/C-grade cells — Grade-A cells are safe, durable and hold their charge.
Full 11000mAh for strong output — welds copper and up to 0.35mm
No inflated claims: 0.1mm copper, 0.35mm Ni-plated, 0.35mm steel, 0.2mm pure nickel.
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.
320×240 HD 2.0-inch color screen
Ditches the low-res 128×160 display for an original, smooth, human-friendly interface.
Smart hand-control pen
A manual button controls trigger timing anytime; removable alumina-copper pins swap without changing the shaft; the thick copper lead runs low-resistance and cool; the front-facing outlet avoids drag, with a 40cm working length.
With USB output — a welder and a power bank
5V/2.4A USB output for two-in-one use.
Safety-focused structure
The board and battery aren't stacked, so heat won't compromise battery safety or life.
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.
