The Across International AIVAF-200-mini Compact Arc Melting Furnace is a benchtop, high-performance metal melting system that can flip alloy ingots for multiple melting cycles without disrupting the protective gas atmosphere and can prepare multiple samples simultaneously, making it ideal for universities, research laboratories and institutes working with refractory metals, metal carbides, and alloy sample preparation.
This small arc furnace features a water-cooled copper crucible with five melting stations, allowing multiple samples to be prepared efficiently while helping prevent cross-contamination. Its mechanical arm flip mechanism enables alloy ingots to be turned and remelted through multiple cycles without breaking the protective atmosphere, improving sample uniformity and workflow efficiency. The system also includes observation windows, internal LED lighting, water-cooled chamber components, and an optional suction casting device capable of producing small metal rods, making AIVAF-200-mini Compact Arc Melting Furnace a versatile solution for laboratory-scale arc melting and casting applications.
Main Features
1. Observation windows on the front and left, LED lighting inside the chamber for monitoring arc melting.
2. Vacuum chamber, copper crucible, and arc electrode all use water cooling.
3. Up/down movement uses a steering wheel design; control joystick rotates smoothly.
4. A mechanical arm flip mechanism is used to turn alloy ingots without disrupting the protective atmosphere.
5. Small crucibles in large quantities allow easy preparation of multiple samples while preventing cross-contamination.
6. Suction casting device at the bottom can cast Ø5mm metal rods.
Parameter | Details |
Model | AF-200-mini |
Max Melting Temperature | 3000°C (can melt various refractory metals) |
Water-Cooled Copper Crucible | 5 stations (custom quantities available); each station is a hemispherical cup with 21mm radius (custom sizes available); one station has a suction casting device installed at the bottom |
Vacuum Suction Casting Device | Can cast metal rods of Ø5mm × 65mm (custom sizes available); by evacuating the copper mold, molten metal rapidly fills the mold, producing rods with minimal shrinkage cavities |

What customers say about our store
Quick and reliable service provided! - Scheduled an appointment with Wayne the other day for a Dry Ice order pick up, he will go over and above for his customers to make sure we are well taken care of. Even with a broken foot !
Thanks again Wayne!
You've got my business!
Wayne there has an excellent store, he has everything, really nice stuff at good prices, ultimately very fair compared to others. I will certainly be going back for everything I need. Got some things from a different place and spent 50% more, just go see Wayne first, he seems like he wants to help you out more than sell you out the door.
WOW
I'd like to first start with this business witch is great ,location was easy to find with good directions, the services wayne offers are a excellent industry best, I had items shipped and also picked up at business store front both very easy and quick
Also like to add the quality of the equipment sold as anything with logo extractor king is from my experience also again an industry best!
And last owner and…
Great service. Definitely recommend them to all
