TE185 - Constant current microprocessor control unit

TE 185 is a microprocessor welding control unit for single-phase resistance welders. The welding control unit is used to control the welder parts and, in particular, the thyristor regulating the welding current. TE 185 control unit can be programmed for working under two different operating modes: standard one and constant current. It is possible to program and to store up 15 different welding programs. All the programs can be recalled directly from the keyboard and 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.

• 15 welding programs selectable by keyboard and by an external device.
