The tip uses a novel threadless fixing system whereby the nozzle is inserted into the head and is locked into place by twisting through a 1/4 turn. This patented feature allows the desoldering nozzle to be quickly and easily changed. It also improves the thermal transfer from the desoldering head to the desoldering nozzle, providing a faster heat-up time and recovery time. Additionally, because there are no threads in the head that tend to sieze, maintenance and running costs are reduced.
