Mathey Dearman MiniMag XM - Manual (Page 9)

11. The Oxy/fuel Hoses of the Machine Torch (A) should be wrapped (1) full turn around the
pipe to help support the weight of the Hoses when cutting pipe. The rotation of the MiniMag XM
around the pipe should be opposite the direction of the wrapped Hoses so that the Hoses are
unwrapped as the Machine travels around the pipe. Never allow the hoses to be dragged through
the molten slag.
12. When using the 12’ / 3.7m Extension Cord between the MiniMag XM Base Unit and the
Motor Control Box, make sure the Oxy/fuel Hoses and Extension Cord are supported. Failure to
do this may cause the Machine to drift from the cut line or become disengaged from the pipe.

Mathey Dearman Sales Department for details on making the Guide Strip.

The MiniMag XM should never be operated without the Heat Shield (3).
20. Use of the MiniMag XM for a purpose other than cutting and beveling the pipe or plate (i.e.
