3.4.1
Welding Ground System
The welding ground system consists of four spring-loaded copper brushes that
contact a copper disc inside each headstock assembly. The ground cable from each
welding power source is connected to one of two ground studs located on the right
side of the positioner base as you face the back of the cell.
CAUTION!
Make sure all ground retaining hardware is secure. If connections
are loose, arcing can occur and cause the insulator to melt.
3.4.2
Locking Pins
The MRM2-750 S3X positioners are equipped with fixture locking pins that
prevent the trunion from turning when the robot is welding.
3.4.3
Arc Shield
DANGER!
Do not operate this equipment unless the arc shield is in place or eye
damage can occur!
Each side of the MRM2-750 S3X positioner is equipped with two sheet metal
screens that run the length of the positioner to visually separate the loading zone
from the welding zone. These screens act as a shield to protect the operator from
the arc radiation and sparks produced by the welding operation. Do not operate this
equipment unless the arc shields are in place.
