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.
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.
2-inch full-color LCD
Auto / manual modes.
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.
