4. Use wire nuts to connect wires, as indicated
in
Figure 9. Twist all three wire nuts onto
their respective wires and wrap them with
electrical tape so they will not come loose.
The voltage conversion MUST be performed by
an electrician or qualified service personnel.
IMPORTANT: To perform the voltage conversion,
rewire the motor to the new voltage, rewire the
power transformer, correctly set the overload relay
dial, rewire the welding transformer, and install
the correct plug, according to the provided wiring
diagram.
Note: If the diagram included on the motor
conflicts with the one on
Pages 58– 59, the
motor may have changed since the manual was
printed. The diagram provided inside the motor
wiring junction box supersedes what is printed in
this manual.
