Automatic Bussing Machine

Used for automatic interconnection of PV cell strings

An automatic bussing machine adopts induction welding and can be applied to 5BB-12BB solar cells of 156-210mm. The soldering precision is high. The busbar overlap area exceeds 80%, and the deviation is ±1mm. The bussing machine features a small size and is suitable for safe and stable production of various solar strings. The soldering stringer is an indispensible machine for solar string production.
