Where I work we have four and three of these are mounted on machines that work to weld profiles on conveyor belts, there are both the old models and this one here and I must say that they are very good products. Sometimes it happens that the power goes out in the company and they turn off when they are at maximum temperature, only once a resistor burned out, all the other times they started working perfectly again. They have only one major flaw: the brush holder holds the brushes with a tab that sooner or later breaks because it has to be opened and closed when you change them.
You have about a 10 degree window to weld PVC you can definitely do it make sure you have a good thermometer test 5 mm inside of your nozzle make sure your temperature is correct and you can do it... If you exceed the temperatures which is very easy you get chlorine gas
