WELDING CONTROL UNIT TE 183 

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.

MAIN FEATURES

	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
