Device concept

Base unit with cleaning unit

Applications The cleaning device is intended for the cleaning of welding torches in automated

steel applications. The cleaning device is designed for use:

In the automotive and supply industry

In equipment engineering

In chemical plant construction

In mechanical engineering

In rail vehicle construction

In shipyards

The cleaning device consists of

a base unit – the Robacta TC 2000

ext. / Robacta TC 2000 ext. US and a cleaning unit – the Cleaning Unit

TC 2000 in various designs

The cleaning device is designed to clean a variety of different welding torch geometries. The components are housed in a robust housing. The compact design permits installation in the smallest of spaces.

The cleaning device is largely maintenance-free, since there are no parts subject to mechanical stress.

Warning notices on the device

The device has safety symbols and a rating plate fitted. These safety symbols and the rating plate must not be removed or painted over. The symbols warn against operating the equipment incorrectly, as this may result in serious injury and damage to property.

Operating principle

As soon as the cleaning device is connected to the grid, the 28 (page 28)

lights up. The capacitors, which store the energy for the cleaning process, are discharged and no outputs are actuated.

NOTE!

In order for the capacitors' charging process to begin, the following prerequisites must be met:

Base unit connected to the grid

▶

Base unit connected to the robot control

▶

Interconnecting hosepack of cleaning unit connected to the base unit

▶

The 'Quick Stop' signal must be set

▶

Before the capacitors are charged, the device temperature is checked. If it is

within tolerance, the capacitors will be charged for the cleaning process. If the operating temperature is exceeded, the overtemperature 28 (page

28) will light up. In this case, the charging process of the capacitors will

only take place after cooling down to the permissible operating temperature.

After 20 seconds of charging time, the 'Ready' signal will be output to the ro-

bot control - the 29 indicator (page 29) on the device will ﬂash. As soon as the capacitors are fully charged, the indicator will light up permanently. Although after 20 seconds the maximum magnetic ﬂux density is not yet available to the device, the cleaning process (discharge process) can be initiated by means of the 'Cleaning Start' signal. For setup purposes, the cleaning process can be triggered manually by means of 29 (page 29) on the device. After 50 seconds of charging time, the maximum magnetic ﬂux density is available for the cleaning process. For the exact ratio of charging times to available magnetic ﬂux density, please see the diagram below.

with a check of the device temperature. If a cleaning process has finished incorrectly, the 'Error' signal will be output. The cleaning device once again initiates the charging process of the capacitors. If the cleaning readiness is 'Ready', another cleaning process can be carried out.

NOTE!

If the robot control deactivates the 'Quick Stop' signal during the program sequence, the cleaning device program sequence will be aborted immediately.

For safety reasons, the capacitors are discharged via the cleaning coil.
