gage above the wheel is used
to
check for
complete removal of the flash. The
saw
weld
should pass freely through the gage.
The grinder circuit is coupled through the
annealing side of the welder switch. When
the welding lever is depressed, the circuit
to
both the annealing switch and the grinder is
open.
If
the grinder
motor
is running while
a
weld is being made,
it
will momentarily
shut off when the welding lever is depressed.

For general metal cutting and wood work-
ing, the Job Selector Dial
on
your machine
will
serve
as
a
guide. While there
are
15 basic
types of DoALL band tools
to
be used
on
the
machine, three of these, the precision saw,
the buttress
saw
and the claw tooth
saw
will
serve
most
shop purposes.
DOALL Precision
saws
are
designed for
fine precision cutting of metals. Buttress
saws
were
developed for faster cutting of wood,
plastics, and non-ferrous metals. They
are
also used for extremely heavy work thick-
nesses
of ferrous-type alloys. They have
a
coarser
pitch than the precision
saw.
The
claw tooth
saw
bands differ from other hard
edge flexible-back bands in that the teeth
have
a
positive rake angle. The durability of
the hard edge plus the faster penetration of
the forward slanting teeth results
in
a
band
of superior performance for many operations.
The above types of
saws
are
offered
in
