PS900 soldering system for PV tabbing and bussing applications has STV-DRH40 hoof tip geometry said to optimize the power delivered to the solder joint, and a temperature-sensitive heater to minimize thermally induced stresses on cell surfaces. Incorporates SmartHeat technology said to produce and maintain a specific, self-regulated temperature with a heater that requires no calibration and responds directly to thermal loads. Works with two solder alloys for solar cell soldering.
