Series 12.5C & 12.5V - This element is what the industry considers "standard" for a 1300 C element. It is a small gauge wire (under 1.5 mm) wound in a tight helix and then strung into a standard ceramic clamshell or flatplate. In our case, we also string them into our Vulcan heating elements, that allow us to provide ANY bore size or shape without costly tooling charges or prohibitively long engineering or manufacturing delays. The heating elements have been the workhorse of the industry for years and are great elements for operations up to 1200 C or intermittent operation to as high as 1250 C. They allow the most flexible variation of volts, as well as watts for almost any size. They are not a good choice for someone operating above 1200 C for long periods or for someone operating above 1250 C for any length of time. Of course, as with all MELLEN heating elements, the watt density for the standard elements are kept as low as possible and always below the wire manufacturers recommendations for long element life. Advantages - 1. Industry standard so it will fit in competitors furnaces
2. Available in almost any voltage
Disadvantages -
1. Smaller wire
diameter means less life above 1200 C and short life above 1250 C
