Robot welding
Prerequisite A robot interface or field bus system is needed in order to be able to control the power
source from a robot control unit.
General 2-step mode is selected automatically if a ROB 4000 / 5000 robot interface or field bus sys-
tem is connected. The mode can only be changed using the Mode button when the robot
interface or field bus has been disconnected from the LocalNet.
If a ROB 3000 robot interface is connected, any mode (2-step mode, 4-step mode, special
4-step mode, etc.) can be selected.
More information about robot welding can be found in the operating instructions for the ro-
bot interface or field bus systems and in the "Robot-interface" leaflet (42,0410,0616).
