The PCT will then program the dialysis machine to the patientâs settings, assess and prepare the vascular access and connect the dialysis tubing to the access. The PCT will also look at the access to make sure it is in good working order. A dialysis treatment can take several hours. The PCT will monitor the patient and check vital signs every half hour as well as monitor the dialysis machine for the entire treatment time. After the patient is done dialyzing, the PCT will take the patient off the machine and weigh them again.
Most brass will melt at temperatures as low as 1,650ÂºF (900ÂºC), but a higher maximum temperature will give you a margin of error, and make the brass easier to pour.
Copper's melting point is 1,981 degrees F (liquidus) and 1,949 degrees F (solidus). For brazing, it is important to know the melting points of the metals to be joined and the filler metal. The difference between the solidus and liquidus state is the melting range, which may be important when selecting a filler metal.
