Highlights
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.
Only brand-new Grade-A cells
No high-drain, risky B/C-grade cells — Grade-A cells are safe, durable and hold their charge.
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.
Color screen · 90 levels
A dial-based color UI, controlled with one hand.
