A5. GROUND WIRE:
Do not operate this resistance welder without a
proper ground wire and connection. The ground wire must
be a separate wire that comes into the control through the same
conduit as the two power wires. Grounding cannot be from a conduit
connection.
The ground wire has to be sized to handle a MINIMUM
of 50% of the amperage-carrying capacity of the two
main power wires coming into this control.
The ground wire must be connected to the ground stud
inside this welding control. Look for the stud with the
DANGER sign as shown in the photo to the right.
A6. CONNECTION OF CONTROL WIRING:
A6.1 INITIATION AND SOLENOID HOLES: Drill or punch access holes
to handle the foot pedal or palm buttons, limit switches, and solenoid valves. These
should be at a convenient location in the bottom or back of the cabinet. Install liquid
tight or approved cable through appropriate box connectors.
When doing any punching or drilling in the control cabinet,
be sure to protect the control components from metal
chips. After drilling or punching holes, be sure that all
filings are fully removed!
