A new safety function is already available in all Unitrol soldering controllers. This function maintains a very low soldering pressure until its safe to apply the final soldering force.
HOW IT WORKS: After starting the soldering operation, the electrodes start to close with a low pressure. A Unitrol continuity sensor system verifies when the electrodes close over the metal to be welded. If an obstacle is detected before closing, the electrodes return to a completely open position. It is not necessary to adjust the SOFT TOUCH when the soldering pressure parameters are changed or when the electrode spacing is modified.
