# SS-2500B Tabber Stringer: 2400 Cells/h, 3-20BB > SS-2500B full automatic tabber stringer machine for crystalline silicon solar cells with 2400PCS/H capacity, featuring infrared soldering #### SS-2500B Tabber Stringer: 2400 Cells/h, 3-20BB #### US$ 252000 SS-2500B full automatic tabber stringer machine for crystalline silicon solar cells with 2400PCS/H capacity, featuring infrared soldering ##### Stock: Available | 30~60 days manufacturing time ##### Category: Product ##### Tags: --- --- **Quick answer:** The SS-2500B is a full automatic tabber stringer built for high-speed crystalline silicon stringing. It handles cells up to 210 mm, places ribbon to a positional tolerance around 0.02 mm with ribbon thickness near 1.2 mm, and the machine runs about 8,200 mm long and 1,900 mm wide with a 10 mm allowance. That footprint is driven by the buffer and the inspection station rather than the soldering head itself. Throughput at this level is set by how fast ribbon can be placed and joined without raising the thermal load on the cell, and by how quickly a defective string is ejected. On a large line this is normally the station that decides whether the whole line meets nameplate capacity, so its cycle time should be quoted alongside the MW figure.
