These electrodes are ground on centerless grinder "Centrless". According to the requirements of iso and AWS-quality electrodes made of tungsten to be processed on this machine. "Annealing" – the kind of heat treatment. Crystal structure Tungsten is improving, and achieves greater uniformity of the metal, which facilitates the movement of electrons. "100% of electrodes tested vortex motion." Testing the vortex motion-monitoring of electrical properties field surrounding the electrode during the passage of current. This test detects looseness, cracks or other defects that may affect the quality of the work electrode. iso standards require the control of each series.

Unsound series withdrawn, is controlled by visual and physical means and, where necessary, be rejected. How to grind tungsten electrodes. Common mistake – grinding tungsten abrasive disc. If the grinding Tungsten is not to a centerless grinding machine, the tungsten gets the dirt that was left on the grinding wheels after previous grinding. This leads to the subsequent poor quality the formation of welds.

This makes the servicing of the boiler as efficient, simple and effective. In addition, semi-automatic feed allows you to restore the required level of pressure in the heating circuit in the event of his fall, and the system self-diagnostic controls the appearance of any problems and faults in the boiler. Information about how to troubleshoot the display. Warm reception Detached house in order as well that allows you to create a truly "smart" heating, can work most effectively, and create the most favorable conditions for its owner. This applies to the circulation pumps – they are responsible for starting the coolant from the boiler directly to the radiators or a system such as underfloor. As in the case of boilers, the landlord must strictly control the operation of this device. And for this purpose in modern technology provides "all the amenities." For example, the pump grundfos ALPHA2 equipped led on indications that at any given time you can learn about the value of energy consumption and the state of the heating system.

But even without the master's oversight of such a pump behaves quite rationally. For this the technology of automatic adaptation autoadapt. It allows ALPHA2 recognize the requirements of the heating system and to accurately select the desired setting for the job. Provides the function "night mode" that automatically reduces engine speed to a minimum. That is, at night the heating system operates in power save mode with a decrease in coolant temperature. Such equipment can easily "adjusted" and a job radiator automation.
