APR30 Pneumatic Spot Welding Machine

Pneumatic resistance spot welding for battery tabs

The APR30 Pneumatic Spot Welding Machine is a bench-top resistance spot welder designed for reliable joining of battery interconnects in cylindrical cell packs (e.g., 18650). It uses controlled electrode force (pneumatic actuation) and a high-current, short-duration weld pulse to create a low-resistance metallurgical bond between conductive tabs and cell terminals. A double-pulse welding mode is particularly useful for battery tab welding because it can improve interface conditioning and help stabilise nugget formation, supporting consistent weld appearance and electrical performance.
