The Stresstech Zap Gun is used to attach thermocouple wire to the work piece. Its variable energy provides 5 to 50 watts/second of power for fast attachment of thermocouples by means of a capacitor discharge procedure. Weighing only 10 lbs. the Zap Gun is portable and is easy to use. It will not significantly mar the external surface of the work piece. Wires are easily removed by lighting filing. The Zap Gun’s internal battery can also be recharged on site from a 110-Volt power supply.
