Artech's finger elements are manufactured using NiCr wire through sintered alumina ring beads and have tails terminated with steel connector blocks for connection to the desired power source.Their  hard wearing and robust nature means they are able to withstand the harshest of on site use, as an established pre and post weld heater,with little or no maintenance required.

Standard element maximum working temperature is 1050 Degrees Centigrade,with each finger rated at 120 amps / 1.3 volts.A standard finger element will hold 46 fingers,but many other sizes up to 62 fingers are available,with the number of fingers required being calculated by dividing the total voltage with the individual finger voltage.
