1. Remember the Centre of Gravity (COG)
Mount holes on the base plate that will support the positioner arm to prevent the unit from tipping that may be caused by an unexpected force.
2. Attach the Weldment Correctly
Properly mount the workpiece in order to allow the weldment to be moved easily and safely with little effort.
3. Use Turning Rolls for Cylinders
If a weldment is cylindrical, it can be rolled. In this case, use powered or idler turning rolls. Power rolls provide steady rotation that produces an even circumferential weld. Idler rolls are not powered but can be added in series to support longer pipes and vessels.
4. Keep it Flat
It is very important to keep the unit mounted to a flat, even surface. This prevents it from tipping by an unexpected force. Any positioner that is mounted to a workbench or a stand must also be secured.
5. Connect Ground Current to the Positioner
While welding, a ground current must be connected to the positioner itself. Without proper grounding, electrical parts can be damaged and substandard weld deposits made. All ground cables should also be tightly secured by removing any paint prior to bolting to the carriage.
