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.
Put all of the scraps of one type into the crucible, and apply a layer of baking soda over the metal. Raise the flame on the torch according to the type of metal you need to melt. Copper, brass and gold will all melt between 1700 and 2000 degrees, while iron and steel will not melt until nearly 2800 degrees. Put on gloves and apply the torch flame to the crucible and wait for the metal to melt completely into liquid.
