Switching on
The TC 2013 is ready for operation when the robot control is switched on.
2.5.4
Modes
The welding system is designed for automatic operation.
The program specified for the TC 2013 is designed for automatic operation.
It is possible to choose between manual and automatic on the mode selector switch of the system.
2.5.5
Sequence of operation
The robot is in the basic setting. The welding torch is generally inside the torch cleaner, above the
spray head.
2.5.5.1
Cleaning
After a cleaning program contained in the robot is called up
•
the welding torch is run into the cleaning position of the torch cleaner,
•
the clamping cylinder fixes the torch in the V-block as soon as the welding torch has reached
the cleaning position,
•
the tool air motor starts to turn,
•
the tool unit with the milling cutter runs vertically from above into the torch and cleans the gas
nozzle and contact tip nozzle.
•
If there is a blow-out valve, the chips remaining in the torch can be blown out.
Machining time and tool feed are directly related. If the milling cutter feed is at its maximum, the
machining time should be programmed one second longer. Complete cleaning is not achieved if
the machining time is shorter.
The sensor reports the start of cleaning.
If the cleaning time defined in the cleaning program has ended, the tool unit, then the tool motor
and afterwards the clamping cylinder are returned to the starting position.
Recommendation:
Simultaneous blowing out and cleaning!
2.5.5.2
Spraying
If the clamping cylinder is in the basic setting, the program receives a signal message from a
switch. This feedback starts the next spraying program.
•
The robot runs the cleaned welding torch into the spray position.
