•
Weld only the flat bar under the cabinet, never the cabinet frame itself.
•
Clamp the welding electrode onto the flat bar about to be welded or to the next flat bar
of the cabinet (within 0.5 meters (1'6") 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...200 micrometers; on the flat bars the coating is approximately
20 micrometers. Ensure that the welding fumes are not inhaled.
