"0" Position before connecting DC Cord.
Step 10: Connect Power Cord (K) of the Motor Control Box to 115vac at 50 or 60 Hertz Power Source.
Note: The 115vac MagnaCut XM can be used with a 230–115 VAC Step-Down Transformer (01-0759-008) to
operate on 230 VAC Current.
Warning: The MagnaCut XM Motor Control Box is not designed for use with a 110 VDC Power Source.

arm is function properly.
Warning: Avoid bottoming out the Torch Arm Stop (20) against the Torch Arm Block Assembly (6).
Note: The Torch Arm In and Out Switch (F) should be in the STOP Position for at least one (1) full second
before changing motor direction.
Step14: Move the Unit Directional Control Switch (I) in the direction the MagnaCut should travel.
Note: The Unit Directional Control Switch (I) should always be moved to the STOP position for at least one (1)
full second before changing drive motor direction.
Step 14: Rotate the Unit Speed Control Rheostat (G) to the desired position for the torch if known. If this is the first time
that the MagnaCut is used, rotate the Unit Speed Control Rheostat to the 4 Position. Adjust the Rheostat until the
desired speed is achieved.
Step 15: The Machine is now ready for operation .
Section 9 – Straight-line Cutting
Step 1: Clear the plate or pipe surface of obstruction, slag and other debris.
Step 2: Set the MagnaCut XM on the pipe or plate and move the machine in a twisting motion until all wheels are in full
contact with the pipe or plate.
Note: When cutting pipe, which has a welded seam running parallel to the pipe axis, place the welded seam
between the 11:00 and 1:00 o’clock Position. Place the MagnaCut XM on the pipe so that it will cross the welded
seam just prior to completing the cut.
Warning: The MagnaCut XM is not designed for use on non-magnetic, heavily painted or wrapped pipes or plate
(Consult Mathey Dearman for Special Application).
Warning: The MagnaCut XM is not designed for use on spiral welded pipe as it will lose contact with the pipe
surface.
Warning: Do not start the cutting operation with the machine between the 3:00 through the 9:00 o’clock Position
on the pipe or plate as the piece being cut off will separate the machine from the surface of the material causing
damage to the machine.
Warning: Never place the machine on the piece of pipe or plate that is being cut off.
Warning: The MagnaCut XM must contact a seam weld at 90-degree. When cutting seam welded pipe, the seam
must be between the 11:00 and 1:00 Position as viewed from the end of the pipe. The machine should be placed on
the pipe so it completes cut after crossing the weld seam. The weld height exceeds 3/16 of an inch in height.
Step 3: Attach the Safety Snaps (17) to the MagnaCut XM at points (P & Q).
Step 4: Attach the Safety Cable (27) provided with the MagnaCut XM to the Safety Snaps (17).
Warning: To avoid injury or damage to the machine, always use a safety cable, rope or belt with MagnaCut XM.
Do not use a safety chain as the chain may become engaged in the wheels of the MagnaCut XM causing the
machine to become disengaged from the pipe or plate.
