The most powerful and comprehensive lab scale plasma/arc melter on the market.

If you want more from your arc melter or you need complex alloys, casting, and/or powder, the Arc 500 is worth a look. This is the most powerful and comprehensive plasma/arc melting lab scale product on the market. The big sister to the very popular Arc 200 product, with 100 kW of melting power, at up to 2400 amps, it can perform all the same tasks and has the same modes of operation, just bigger and faster!

There are also two vacuum options: medium (1E-2 mbar) and high (5E-6 mbar). All options are designed for quick cycle times and user friendly operation.

The intended use for the Vacuum Arc Melter is to allow metallurgists and technicians to alloy reactive or nonreactive metals, and cast or atomize these alloys with the least running cost and capital cost, while maintaining a high engineering standard.

Our Arc 500 is highly flexible and configurable

Below are some of the options available (select the schematic drawings to see larger views)

Electromagnetic stirring

We have added a highly effective electromagnetic stirrer to our range of options for our arc melters. This allows complete alloying in one heat cycle without the need to flip and re-melt multiple times. It works with any alloy system and comes in many different specifications to modulate the amount and type of stirring as required.
