into
the
threaded
hole in the top of the shaft.
Note the direction
the rod has to be moved
sideways
in order
to bring
the
shaft
to the center
of
the hole
in the cabinet.
Do not
remove
rod.
7,
Place
the free end of the rod
through
the hole

on the water
lip around
the hole in the cabinet.
8.
Rotate
the point_,,r

CHART
WARNING:
Make sure the branch circuit main disconnect switch or circuit fuses are
removed (or welder plug and cord removed from its receptacle) before removing the
welder cabinet or lid. Placing the "ON-OFF"
switch on the welder in the "OFF"
position
does not remove voltage from the power leads inside the welder - BE SAFE AND BE
ALIVE,
OPEN THE BRANCH CIRCUIT.
PROBABLE
CAUSE
