OPERATING INSTRUCTIONS (CONT'D.)
POWER SUPPLY
The DC III drive operates on 120 volt, (42VAC), (240VAC), 50/60 Hz. The Circuit
Breaker (O) protects the unit against overload or electrical faults,
CAUTION: IF THE CIRCUIT BREAKER OPENS, FIND AND CORRECT THE
CAUSE OF FAILURE BEFORE RESETTING.
TORCH
The Torchholder (P) will accept any standard American machine torch (barrel
diameter 1-3/8" (34 mm) with 1/4"-square (6 mm) 32-pitch rack). The 32-pitch
pinion is standard. Specify a 24-pitch pinion if desired. The Short Hose As-
sembly (Q) connects the torch to the Quick-acting Manifold Assembly (R).
The supply hoses are to be connected to the open side of the quick-acting
manifold assembly.
Proper torch operation is essential to quality cuts. We suggest that you follow
the torch manufacturers' instructions carefully, being sure to use a clean tip of
the proper size.
MAGNETIC SUPPORTS
Several Types of magnetic supports are available for use with the CIR-O to
stabilize the machine as listed below:
(S) Outrigger Support Assemblies; CON-1010 - used in multiples of two
or four to stabilize CIR-O on plate, cylinders or heads where two legs must
be longer than the other two,
(T) Magnet Foot Assemblies; CIR-9000 - may be used in sets of four or
more to position CIR-O on vertical or out-of-position, flat surfaces.
(U) Leg and Magnet Foot Assemblies; CON-1040 (four required) - may be
used for flat or irregular surfaces.
(V) Offset Leg and Magnet Assemblies; CIR-9002 (four required) - use with
a bevel cutting head or adjustable tip adaptor - to eliminate the "blind" spot
under the ring.
SETUP
A center-punch mark and a radius mark are the only layout required. The Center
Pin Assembly (Z) extends below the CIR-O base and is placed in the center-
punch mark. The CIR-O is then eased down to the work on the center pin. This
movement locates the entire machine "on center." The Rack (W) with Torch-
holder (P) is then positioned over the radius mark.
OPERATION
In order to provide a smooth start, it is recommended that the starting hole be
drilled or pierced inside or outside the radius mark. Center the torch tip over the
radius mark and secure the Rack Stop (X) firmly against the Post Assembly
(Y). [The side of the post assembly to which the rack stop is positioned depends
upon whether the material inside or outside the cut is scrap]. Begin the cut from
the starting hole and, after carriage travel is begun, move the Torch Rack (W)
slowly against the Rack Stop (X). This action "feathers-in" the cut eliminating
a notch.
