Jewelry Applications

The Spirflame® Karat 250 is a worldwide patented multi-cell flame generator producing Hydrogen and Oxygen in the absolute perfect 2:1 ratio by the electrolysis of water. Energy is taken from any 230 vac outlet. The consumption depends on the gas production rate and reaches a max of approx 1000 Watt. The flame heating is electronically selected by user and is then automatically stabilized by the electronic control itself.

The KARAT250® is used with goldsmith and dental labs for platinum, gold, silver
and other noble metal soldering tasks, be it very fine or large.

What Karat250® Users Say

Is the gas pressure once selected, despite to gas consumption variations by the torches, fully stabilized by the electronic control. The KARAT250® can therefore be installed remote from work area. To expand supply to eventual later to be added torch stations simply hook another KARAT250® to your gas lines. They will automatically and evenly distribute the load between themselves.
