Phosgene gas is formed during the welding of work pieces that have been degreased with chlorine-containing solvents. Wear suitable protective clothing and eye protection. Do not inhale fumes and vapors.
12.3 Maintenance and cleaning Once a month, thoroughly clean the robot mount to remove all dirt and welding spatter. Risk of injury due to unexpected start-up For the entire duration of maintenance, servicing, unmounting, and repair work, the following instructions must be adhered to: • Switch off the power supply. • Cut off the compressed air supply. • Pull the power plug. 12.3.1 Cleaning the wire guide This section describes how to clean the wire guide.
12.3.2 Shortening the wire liner 12.3.3 Cleaning the gun neck Unused wire liners or PA liners have to be shortened to the actual length of the hose assembly. Mounting of plastic liners is similar to mounting of wire liners. Refer to the operating instructions of the manufacturer of the wire feeder. Proceed as follows: 1. 2. 3. 4. Plastic liners are used for aluminum. Plastic liners and fastening material are available on request. 5. Figure 8: Shortening the wire liner 6. 2 3 1 4 6 7. 8. 9.
