{"product_id":"sp-msm207","title":"Compact Vacuum Arc Melting System (250 A) with 7 Cavities - SP-MSM207","description":"SP-MSM207 is a compact vacuum arc melting furnace with a non-consumable tungsten electrode and water-cooled copper crucibles. A built-in mechanical manipulator is included for tilting and rotating metal ingots for the re-melting process. A vacuum casting faction fixture can be added as optional. It is an excellent tool for smelting metal alloys for phase diagram research. Note: Upgrade Max current to 250A, since July 15, 2023 SPECIFICATIONS: Features Designed for melting samples \u0026lt; 10g iron-based alloy up to 3000 °C under tiny positive pressure or low vacuum A water-cooled vacuum chamber, electrode, and copper crucible allows arc melting of multiple samples without cross-contamination Powerful arc melting power supply enables reliable, stable arc ignition Easy electrode tilting and height adjustment via a handwheel A built-in mechanical manipulator for tilting and rotating samples without breaking the vacuum A tinted observation window on the front for monitoring the the melting process Chamber Door Front Window Flashlight Insert Manipulator Vacuum Pressure Gauge Please select either an anti-corrosive capacitance diaphragm gauge or a mechanical vacuum pressure gauge. Power Supply 7000W (250A) arc melting power supply with ETL Listed 208-240VAC, 1 and 3 ph, 50\/60Hz. @240V 1 Ph: 32A (50A breaker) @240V 3 Ph: 16A (30A breaker) Output DC output duty cycle: 60% @ 250A, 100% @ 200A Minimum DC current output: 10 A Foot pedal control of the output current Tungsten Electrode 4 mm Dia. tungsten electrode with water cooling Easy electrode tilting and height adjustment (30 mm max) for multiple-cavity melting Capable of melting samples \u0026lt; 10 g iron-based alloy in each cavity up to 3000 °C. A.4.5 g B.10 g Copper Crucible Water-cooled copper crucible plate with 7 cavities of 25 mm Dia. × 8 mm depth (2 ml) (Fig. 1) The customizable copper crucible is available upon request at extra cost (Pic 2 ). A larger arc melter, MSM200 is also available for Fe \u0026lt; 300 g A vacuum casting module, MSM208 is also available (Fig. 4). Fig1 Fig. 2 Vacuum Chamber Water-cooled vacuum chamber with dimensions of Φ 182 mm × 225 mm H A Φ120mm front door for easy sample loading and retrieving A tinted observation window on the front for monitoring the melting process A built-in wobble stick for sample flipping. Vacuum Pump (Optional) The vacuum level is dependent on the vacuum pump used: 10^-3 torr via a mechanical\/roughing pump. ( Roughing Pumps ) 10^-5 torr via a turbopump. Water Chiller \u0026amp; Gas (Optional) Water cooling is required (not included) for the copper hearth and electrodes. Please consider our KJ-5000 recirculating water chiller. Water-tube for MTI Water Chiller is Size: 12mm O.D x 8mm I.D High-purity inert gas with at least 5N purity (\u0026gt;99.999%) is required (not included) 5% Hydrogen + 95% Argon gas may be used to prevent oxidation during the melting process Compliance CE certified UL\/CSA certification by NRTLs is available at an extra fee. Related Article Layered amorphous silicon as negative electrodes in lithium-ion batteries, Journal of Power Source, 332(2016), Leyi Zhao, et. al Application \u0026amp; Warning Notes A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 psi for safe operation. Click here to learn about the installation of a gas regulator (Pic.1) To avoid any damage to the mechanical pump or turbopump, please install an Inline Particle Trap (maximum 1E-4 Torr vacuum with turbopump) on the pump inlet port (Pic. 2) Must Wear Welder Glass or Auto Welding Shade while observing the Arc while welding. The unit is designed for arc melting operation under tiny positive pressure or low vacuum (0.01 – 0.11 MPa pressure, or positive 0.01 MPa to negative 0.09 MPa pressure). Never operate the unit at high pressure! During the arc melting operation, never allow the electrode to touch the material or the copper crucible! Do not operate the mechanical manipulator during the melting process. Option: The user may use quartz tube shielding to effectively reduce the splash and spilling while arc melting.
