Description
The SUNKKO 737DH 4.3KW Spot Welder is a multifunctional battery spot welding machine designed for precision welding applications, particularly for lithium battery pack assembly and repair. With adjustable welding power and multiple pulse modes, it provides greater control over welding different materials and thicknesses.
The machine features a delayed welding function with three adjustable power levels, allowing users to achieve precise and consistent welding results. Its induction-based automatic current release mode is suitable for battery pack welding, while the adjustable pulse power control helps accommodate different welding materials and thicknesses.
The SUNKKO 737DH supports 2, 4, 6, and 8 pulse selections, providing flexibility for different welding requirements. Welding current can be monitored through the built-in current display, allowing users to observe the output during operation.
It offers two welding configurations: a fixed welding head and a movable welding pen. An external foot pedal control can also be used to provide convenient hands-free operation and better control during repetitive welding tasks.
