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, 2023

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

Tungsten Electrode
|
-
6 mm Dia. tungsten electrode with water cooling
- Easy electrode tilting and height adjustment (30 mm max) for multiple-cavity melting
- Capable of melting samples < 200 g iron-based alloy in each cavity up to 3500 °C.

Copper Crucible
|
-
Water-cooled copper crucible plate with one large capacity with several small cavities (Pic. 1-2).
- Round cavity: 70 mm diameter x 15 mm Depth (Included)
-
Rectangular cavity: 100 mm L x 40mm W x 15 mm Depth (optional at extra cost)
- Three 25mm dia. × 12.5 mm Deep small cavities are used for Ti melting to reduce the trace oxygen inside the chamber before processing, or small samples for < 20 g
- In order to melt the alloy uniformly, double-side melting is required
-
Optional: Crucile with vacuum casting is available upon request. ( Pic. 4)

Compliance
|
- CE certified
- UL/CSA certification by NRTLs is available at an extra cost
|
Upgrade option
|
- This arc melter also can be used for preparing hydrogen plasma metal hydride with 30% H2 + argon gas, (examples: LaNi5H6, MgH2, and NaAlH4
-
H2 gas detector and automatic burner and 2-channel MFC gas delivery system must be integrated with the melter
- Please contact the MTI engineer team for safe operation and training
