Description
The design of the furnace permits it to be repeatedly evacuated and flushed with gas. The system evacuation-gas-evacuation offers great advantages, particularly when melting oxidation-sensitive samples, such as ferro-alloys, with a large area (powder). The oxygen is “washed” away efficiently.
The HF-generator has a stated effect of 15 kW. The generator is sealed into an enclosed cabinet. The structural design consists of aluminium profiles with outer panels and fittings of aluminium. Two sides are fitted with removable shutters with special locks. The operating controls, instruments and HF-outlets are positioned on the front of the generator, water and power supply connections on the rear.
The HF-generator is equipped with high and low impedance output terminals and a high-tension changeover switch. The output effect is continuously adjustable by means of a knob on the generator's front panel, adjustment in the low-impedance range 60-100%. A synchronous-motor-driven time relay, adjustable from 0-6, 0-60 sec, 0-6, 0-60 min. and 0-6 hours, is built into the generator.
