The TZ2003-2 Two Zone Controller via welding machine is designed to control various heat treatment processes by closely monitoring and adjusting the set point temperature and the ramp rate. It incorporates the latest microprocessor based technology and is simple to set up and operate. Control setting is by means of push switches and an LCD screen provides visual indication of the set point and the actual temperature. The portable two-zone controller is designed for post weld heat treatment and preheating applications TZ2003-2 takes the output from a transformer or welding machine (AC/DC). Also requires 110 volt AC power supply. Stainless steel cabinet. Two temperature controllers with ramp soak capabilities (1/8 DIN Digital Controllers). Two 200 amp ALBRIGHT contactors (100% duty cycle). Two 110 volt neon's. 2 x two way on off switches. 1x5ampfuse. c/w +/- Input leads from TZ2003-2 to welding machine. Maximum output per circuit 3 x 60/80 volt ceramic pad heaters = 135 amps. TZ2003-2 requires 16 kilowatts power source to operate 6 x 60/80 volt ceramic pad heaters. Note 1: One two-zone controller (TZ2003-2) is capable of heating an area up to 3.75 sq. ft. approximately using a total of 6 x 60 volt ceramic pad heaters. Note 2: One two-zone controller (TZ2003-2) is capable of heating an area up to 5 sq. ft. approximately using a total of 6 x 80 volt ceramic pad heaters.
