The bright OLED screen shows real-time welding information, making adjustments quick and easy. No guessing, no trial-and-error — just accurate, repeatable performance.

🔋 Built-In 5000mAh LiPo Battery

Portable and powerful, the internal 5000mAh lithium polymer battery provides excellent endurance for extended welding sessions. Recharge quickly and conveniently using the Type-C charging port.

Unlike plastic-bodied mini welders, the DH-30 features a solid metal casing for better durability, improved heat resistance, and a more premium, professional feel.

🔧 Upgradeable & Future-Ready

Supports U-disk firmware upgrades, so the device can stay optimized with performance improvements and updates over time.
