Battery Tab Spot Welders

Dual Pulse Industrial Spot Welders

Recently, more and more people are looking for custom built and/or rebuilt battery packs. The reason for the increase in interest comes from the ability to get a higher quality battery pack for less money. By providing customers with higher grade cells at lower than retail prices, it is easy to gain loyal, life-long customers while still making a significant profit.

Building battery packs consists of welding thin nickel tabs from one battery cell to another. Sunstone Engineering's CD 320 watt second dual pulse spot welders are the perfect battery tab spot welders for battery pack manufacturing when combined with the WH2125 weld heads.

The spot welder’s dual pulse feature provides strong, clean, repetitive welds. The first pulse heats the weld surface to eliminate contaminates and to seat the welding electrode tips. The second pulse then performs a strong spot weld. This process is designed for battery pack spot welding.

Sunstone provides package deals for battery pack manufacturers. The most popular battery spot welder package consists of the CD320DPM2 and the WH2125. The 320 watt second spot welders provide the ability to fine-tune the weld energy for welding nickel tabs to batteries while also providing enough power to weld thicker terminal tabs.

The WH2125 weld head provides fine control of weld pressure ranging from 3 to 17 lbs. Each electrode’s pressure setting can be adjusted individually. The WH2125 is available for either pneumatic or manual operation.
