Electric welding
It is not recommended to fasten the cabinet by welding.
•
Weld only the flat bar under the cabinet, never the cabinet frame itself.
•
Clamp the welding electrode onto the flat bar that is to be welded or to the next flat bar
of the cabinet (within 0.5 metres of the welding point).
WARNING! If the welding return wire is connected improperly, the welding circuit
may damage electronic circuits in the cabinet. The thickness of the zinc coating of
the cabinet frame is 100 to 200 micrometres; on the flat bars the coating is
approximately 20 micrometres. Ensure that the welding fumes are not inhaled.
