Section 6
MagnaCut XM and Motor Control Box Warranty
1. The Mathey Dearman, Inc. Sales Department should be contacted prior to performing any maintenance on
the MagnaCut XM. The disassembly or adjustment of any part of the MagnaCut XM or the components of
the MagnaCut XM Motor Control Box will void the Machine’s Warranty unless authorization from
Mathey Dearman, Inc.
2. If it is necessary to replace the DC Cord (J), the Motor Control Box (13) should be returned to Mathey
Dearman, Inc.
3. The Wheel Mounting Brackets (Q) are not to be removed from the machine. Removing the Wheel Mounting
Brackets will affect the tracking and may cause the Drive Motor (1) to overheat.
4. The MagnaCut XM should be returned to Mathey Dearman for replacement of any parts not listed in the Parts
List.
Section 7 - Safety Tips
1. The MagnaCut XM should not be used on pipe or plate with a wall thickness of Three (3) inches / 76mm. The heat
generated by the torch when cutting thick wall pipe will cause the wheels of the MagnaCut XM to lose magnetism-
disengaging it from the pipe or plate.
2. The use of a hammer or other object to strike the torch arm or to move the torch to the cut line is strongly
discouraged. If there is evidence that a hammer or other object is used to move the torch to the cut line, the
Warranty will be voided.
3. A Safety Cable should always be used with the MagnaCut XM to avoid injury to the operator and damage to the
machine should it become disengaged from the pipe. It is recommended to use a Safety Rope or Cable, not a Safety
Chain. The Chain may become engaged in the wheels of the MagnaCut XM, causing the machine to become
disengaged from the pipe or plate.
4. Do not operate MagnaCut XM in an explosive environment.
5. The MagnaCut XM should not be used in an extremely moist environment or rain due to the risk of electrical shock.
6. The use of the MagnaCut XM to cut pipe or plate having a wall thickness less than 3/8 of an inch (9.5mm) or more
than a 3” (76mm) thickness is not recommended.
7. The MagnaCut XM must contact the seam weld at a 90˚ angle. The seam must be between11:00 and 1:00 Position.
The machine should be placed on the pipe so it completes the cut after crossing the weld seam. In no event should
the weld seam height exceed 3/32 of an inch /2.3mm in height.
8. The MagnaCut XM cannot be used on pipe having an Epoxy, Carbo-Zinc, Plastic or other synthetic coating up to
.015 of an inch or 15 mils in thickness. The grooves in the Wheels should be kept clean or the machine will suffer a
loss in magnetism.
9. Make sure the Oxy/Fuel Torches or the Plasma Torches are installed through the Hose Support (24), so the hoses do
not become engaged in the wheels of the machine causing the machine to become disengaged from the pipe or plate.
10. The DC Cord (J) between the Motor Control Box and the MagnaCut XM Base Unit is to be installed through the
Hose Support (25), so the cord does not become engaged in the wheels of the MagnaCut XM causing the machine to
become disengaged from the pipe or plate. (Use Safety Cable at all times.)
11. When cutting pipe or plate there should be sufficient slack in the Oxy/Fuel or Plasma Hoses so that the MagnaCut
XM can make a square cut without becoming disengaged from the pipe or plate to drag the hoses around the pipe or
plate.
12. The machine is not designed to support the weight of the hoses. To help support the weight of the hoses when
cutting pipe, the Oxy/Fuel Hoses of the Machine Torch or Plasma Torch (A) should be wrapped one (1) full turn
around the pipe,. The rotation of the machine around the pipe should be opposite the direction of the wrapped hoses
so that the hoses are unwrapped as it goes around the pipe.
Warning: Never allow the hoses to be dragged through the molten slag.
13. When using the 12 Foot Extension Cord between the MagnaCut XM Base Unit and the Motor Control Box, make
sure the Oxy/Fuel or Plasma and Extension Cord are supported. Failure to do this will cause the machine to drift
from the cut line or become disengaged from the pipe.
