8.4.6 Welding
Welding causes some high current flows and voltage peaks on the machine. It
should be noted that the electronics of the control system may be damaged, if the
welding current can get through the control unit itself.
So, when welding, it should be taken care to prevent high currents from going
through the control units or through the CAN bus.
Follow carefully the following instructions.
Disconnect all the connectors from the control units before welding.
Generally, even if the control system power is disconnected, welding should be
done carefully and by following appropriate safety measures. Welding grounding
should be connected close to the welding point to avoid long distance high current
flow through machine frame.
