SUNKKO SPOT WELDING MACHINE 737DH WITH 70B

## SUNKKO 737DH with 70B High Power Precision Intelligent Spot Welding Machine

The SUNKKO 737DH High Power Precision Intelligent Spot Welding Machine with 70B Welding Pen is a professional-grade battery spot welder designed for lithium battery pack assembly, nickel strip welding, stainless steel mesh welding, and industrial spot welding applications. Equipped with advanced intelligent pulse welding technology and high-power output performance, the SUNKKO 737DH delivers precise, stable, and efficient welding results for both professional and industrial battery manufacturing environments.

The SUNKKO 737DH features a microcomputer-controlled intelligent welding system that provides accurate pulse welding control and real-time welding current monitoring. Its high-power 4.3KW output and welding current range of 120~1200A ensure strong welding penetration and reliable welding performance for various battery pack applications. The machine supports both fixed spot welding and mobile spot welding modes, giving users maximum flexibility for different welding requirements.

This intelligent spot welding machine is specially designed for assembling and repairing lithium battery packs, portable chargers, circuit boards, stainless steel mesh, and other precision welding projects. The included 70B high-power welding pen provides accurate and efficient spot welding performance with excellent conductivity and low heat loss. The advanced welding system creates clean, firm, and reliable solder joints while minimizing damage to sensitive battery cells.

One of the major highlights of the SUNKKO 737DH is its delayed welding function with three-level power adjustment technology. This advanced feature improves welding precision and ensures stable welding quality, especially for high-capacity battery packs and thick nickel strips. The machine also supports 2/4/6/8 pulse welding selection modes, allowing users to optimize welding strength and reliability according to material thickness and welding requirements.

The built-in high intelligence DIS sensing technology enables automatic trigger welding simply by touching the welding surface, eliminating the need for constant foot switch operation. For precise positioning and advanced welding control, the external foot pedal switch can also be used, making the welding process more convenient and efficient for professional battery pack assembly.

The fixed welding head includes a pressure adjustment mechanism that allows users to control welding needle pressure according to the thickness of the welding material. This improves welding consistency, reduces false welding, and ensures durable electrical connections.

Designed with industrial-grade components and an efficient cooling structure, the SUNKKO 737DH provides stable long-term operation without overheating. Its compact and durable design makes it suitable for workshops, battery manufacturing units, repair centers, and DIY battery projects.
