Product Data Sheet

SUNKKO A330H Series Gantry-style Pneumatic Battery Spot Welder – Capacitor Energy Storage Pulse Welding Machine

The SUNKKO A330H Series Gantry-style Pneumatic Battery Spot Welder is a super high-power industrial capacitor energy storage pulse welding machine specially designed for lithium battery pack manufacturing, energy storage systems, EV battery production, and heavy-duty metal welding applications. Equipped with advanced capacitor energy storage pulse technology and a precision gantry pneumatic welding structure, the A330H delivers extremely stable, accurate, and powerful welding performance for professional industrial production environments.

The A330H features an ultra-high 42KW pulse output with maximum welding current up to 7000A, making it suitable for welding thick pure nickel, nickel-plated strips, copper materials, LiFePO4 battery connections, and high-capacity lithium battery packs. Its advanced microcomputer-controlled system ensures precise pulse energy control, consistent welding quality, and minimal heat damage during continuous operation.

Designed with a durable 304 stainless steel gantry frame, the machine offers exceptional stability and adjustable height positioning for different battery pack sizes and welding applications. The pneumatic welding head uses buffering technology that independently adjusts welding needle pressure, reset speed, and downward pressing speed for improved welding precision and reliability.

The integrated laser red dot alignment system helps operators achieve fast and accurate welding positioning, while the LED welding needle lighting system improves visibility during detailed work. A real-time digital LED display monitors voltage and current output to help users evaluate welding quality during operation.
