FIELD: electrical equipment. SUBSTANCE: at a check, for example, the positor heater is inserted in the holder body with the heat conductor under a spring connecting the positive supply line to the contact, the supply voltage is cut in, sustained in the heated state at the minimum current due to heat insulation in the cavity from the ambient air, which provides for reduction of consumption of electric power in service, for example, the posistor welder of thermoplastic films connected to the output contacts of the holder during interoperational intervals is also inserted in the holder body, where the welder is practically not cooled which ensures reduction of electric power consumption. EFFECT: reduced consumption of electric power at checking of manufactured posistor hand tools and in their service. 2 cl, 1 dwg |
