TE183 - Three-phase microprocessor control unit

The TE 183 is a microprocessor welding control unit for direct current resistance welders. The welding control unit is used to control the welder parts and, in particular, the thyristors regulating the welding current. It is possible to program and to store up 63 different welding programs. All the programs can be recalled directly from the keyboard; 15 programs can be recalled from an external source by means of a PLC. Each program can assume all the configurations included between the simplest 4 times cycle, up to the most complex one, which can include the slopes, the pulses, the postheating, the forging and the minimum and maximum current limits.

• 63 welding programs

• 16 programmable parameters for every program

• Control of 3 solenoid valves 24 Vdc 7,2 W Max with protected output against short circuit

• Display of the welding current in kA

• Counter of the performed welds

• Output of endcycle with relay, also selectable as interlock

• Minimum and maximum limit of the welding current for each program

• Output signal for out-of-limits spots with relay

• Automatic compensation against voltage drops

• Stepper function against electrodes wear

• Restart key and outputs enabling under Watch-dog control

• Serial communication by means of insulated RS-232 interface (optional)

• Removable key for programming or for run.

• Integrated ammeter with four different capacities to select (24,48,60,120 kA). By using current transducers with sensibility 0.5X it is possible to obtain the following capacities: 48, 96, 120, 240 kA.

• Key to select foot control or two hands control

• Possibility to eliminate the autoretain of the start signal during the welding process

• System to protect the rectifier from overloading

• Self-adjustment to the network frequency 50/60 Hz
