SP-MSM200 is a compact arc melting furnace with a water-cooled copper hearth to melt metallic samples up to 200g (Fe as ref.). A built-in mechanical manipulator is included for tilting and rotating metal ingots for the re-melting process. This furnace also can be used for hydrogen plasma arc melting ( please see option note at the bottom of the page )Note: Upgrade Max current to 250A, since July 15, 2023SPECIFICATIONS: Features Designed for melting single samples of 200g (Fe alloy) up to 3500 °C under Ar gas. Water-cooled vacuum chamber, electrode, and copper hearth with one larger cavity (round or rectangular) and several small cavities. Powerful arc melting power supply (8 KW) enables reliable, stable arc ignition Easy electrode tilting and height adjustment via a handwheel A built-in mechanical wobble stick for tilting and rotating samples without breaking the vacuum A tinted observation window on the front for monitoring the melting process Front tinted window Manipulator Chamber Door Flashlight Insert Vacuum Pressure Gauge Pirani capacitance diaphragm gauge Power Supply 208 - 240 VAC,1ph, 50/60Hz, 7.3 kW Output DC output: 315A/22.6V @ 60% duty cycle (max. 6 min continuous operation every 10 min)244A/20.0V @ 100% duty cycle (continuous operation) The HF function is included for easy arcing without contact with samples. Optional: 25 KW, power supply ( 460V, 3 Phase, 630A VDC Max), is available upon request for refractory alloys, such as Mo, Ta, W based alloy Pic.
