6.11 Safety
6.11.1 Personal Safety
Moving parts which according to the EU machinery directives might cause per-
sonal injury are interlocked via the robot holding device and emergency circuit.
Such functions are manual wire feed and mechanical cleaning of the gun.
Figure 23 on page 51 shows the build-up of the PIB interlocking system.
If national regulations require that also the power source shall be interlocked, the
interlocking system can be completed by a relay opening the control circuit of the
power source.
On manual wire feed via the welding gun or the push-button of the feed unit, the
wire can be fed without holding down the holding device up to max. 6 metres per
minute. The speed will increase as long as the push-button is activated. For speeds
higher than 6 m/min the holding device must be held down. For ARCITEC/LRA
the speed is constant - 5 m/min.
Manual wire feed: Appendix 2 on page 63, Possibilities and limitations.
