Features

• Adopts high-quality, low-resistance MOS with max working current of 2500A — ideal for spot welding nickel plating, pure nickel, and copper sheets.
• Supports multiple charging methods: fast charging, slow charging, and battery charging — enabling continuous, stable operation.
• Constructed with an all-metal aluminum shell for fast heat dissipation; equipped with super farad energy storage capacitors for high energy, long life, and safety.
• Offers two trigger modes: auto and manual; includes features like solder point counting, temperature detection, LED light, and firmware upgrade support.
• Features an HD LCD color screen with multi-language support: Chinese, English, and Russian.
• Comes with aluminum oxide copper welding pins — hard, durable, non-melting, and non-stick to nickel strips; double head design enhances pin usage.
• Includes two types of spot welding handles: split handle (SWP25) and integrated handle (WP30); made from 25mm² ultra-soft, multi-strand copper wire with nickel plating — offering flexibility, low resistance, high overcurrent capacity, and anti-oxidation durability.
