Product Resources

I. Machine Preparation

(see Diagrams 1A, 1B and 1C)

  1. Check to assure the machine is complete and not damaged from shipping. Please notify the distributor where the machine was purchased if a problem exists.

    2. Diagram 1A

  2. H&M machines are equipped with the patented Cuboid Spacers to accommodate standard pipe diameters. Special Cuboid Spacer Bolts for all models are available for pipe sizes other than standard (refer to Diagram 1A).

    3. NOTE: If your machine was manufactured before the Cuboid Spacer System was introduced, it utilizes separate spacers for each pipe size. Please call H&M at 918-582-9984 with any questions about upgrading your current equipment.

    Diagram 1B

  3. Bolt the four Cuboid Spacers under the saddle. Each side of the Cuboid Spacer is stamped with a pipe size. Bolt the Cuboid Spacers on with the pipe size to be cut facing down, making contact with the pipe to be cut (refer to Diagram 1B).
  4. Attach the standard torch arm and torch holder assembly, or the optional Model “C” Adjustable Torch Holder or the Model “C” Out-of-Round Attachment securely to the ring gear.
  5. Position and secure a two-hose machine cutting torch in the torch holder. No pitch rack is required. The two-hose machine cutting torch should have an overall length of 15″ to 16″, or it will not reach the machine’s smallest pipe capacity on a 37.5-degree bevel angle.

    6. Diagram 1C

  6. Store the Cuboids on the back of the saddle (refer to Diagram 1C).

II. Positioning On Pipe

(see Diagrams 2, 3 and 4)

  1. Place the machine on the pipe to be cut. Adjust the boomer assembly by lengthening or shortening the boomer chain until the machine is securely attached to the pipe.
  2. Set the torch to the desired degree of bevel angle by loosening the appropriate wing nuts on the standard torch holder. Position the torch to the desired bevel angle. Make sure to tighten the wing nuts securely after setting the bevel angle.

    3. Diagram 2

    A. If using a Model “C” Adjustable Torch Holder or a Model “C” Out-of-Round Attachment, the bevel angle is set by loosening the “T” handle. See the operation manual for the Model “C” Adjustable Torch Holder or the Model “C” Out-of-Round Attachment for detailed instructions.

  3. Vertical adjustment with a standard torch holder is achieved by loosening the thumbscrew on the torch holder and adjusting the torch tip to approximately 1/4″ from the pipe.

    4. A. The setting for the Model “C” Adjustable Torch Holder or the Model “C” Out-of-Round Attachment is obtained by turning the proper knob. See the operation manual for the Model “C” Adjustable Torch Holder or the Model “C” Out-of-Round Attachment for detailed instructions.

  4. Horizontal adjustment with a standard torch holder is accomplished by loosening the appropriate wing nut on the torch holder, manually positioning the torch tip to the intended line of cut and securely tightening the wing nut.

    5. Diagram 3

    Diagram 3

    A. The setting for the Model “C” Adjustable Torch Holder or the Model “C” Out-of-Round Attachment is obtained by turning the proper knob. See the operation manual for the Model “C” Adjustable Torch Holder or the Model “C” Out-of-Round Attachment for detailed instructions.

  5. The standard beveling machines are manually driven. The operator turns the crank handle, generating travel to the torch during the cutting process.
  6. For motorized machines set the speed control to a LOW setting. Plug into a 110- to 120-volt AC power source and check the power. If the power source is 220 volts the machine will be supplied with a 240/120 transformer.
  7. Diagram 4

    Diagram 4

    Light the torch and adjust to a neutral flame. When the metal has reached a proper temperature turn the high-pressure oxygen valve to the OPEN position, then start the cutting process. Start rotating the ring gear either manually or with an electric travel motor.
    NOTE: If you are unfamiliar with the safe operation of an oxy-fuel cutting torch, ask your local welding distributor for training before using this equipment.

  8. When the cut has been completed turn off the cutting oxygen and remove the machine from the pipe by releasing the boomer assembly.
