listed in the parts list.
Safety Tips
1. The MiniMag XM should never be used to back bevel the pipe or plate. The heat generated
by the torch will cause a loss of magnetism causing the machine to lose contact with the pipe or
plate.
2. Always use the Safety Cable (18) provided with MiniMag XM when cutting to avoid injury
to the Operator, or damage to the machine should it become disengaged from the pipe or plate.
Always use a Safety Rope or Belt, never use a Safety Chain as it may become engaged in the
Wheels, causing the machine to become disengaged from the pipe or plate.
3. The MiniMag XM , with Permanent Magnets, should not be used on pipe or plate with a wall
thickness of more than 2 inches. The MiniMag XM should not be used on pipe or plate with a
wall thickness of more than 3 inches. The heat generated by the cutting torch on thick wall pipe
or plate will cause the MiniMag XM with Permanent Magnets to lose magnetism and become
disengaged from the pipe or plate.
4. Do not operate MiniMag XM in an explosive environment.
5. Do not operate the MiniMag XM in an extremely moisture environment or rain due to the
risk of electrical shock.
6.
The Machine should not be used to cut material thinner than 3/8 of an inch (9.5mm) in
thickness as the Machine may not adhere to the pipe or plate strongly enough.
7.
When cutting with the MiniMag XM, the weld seam should be between the 11:00 – 1:00
o’clock positions as viewed from the end of the pipe. If the Machine crosses at any other point, it
will become disengaged from the pipe. MiniMag XM will lose contact with the surface of the pipe
or plate if it does not contact the weld at a 90‐degree angle. The weld seam should not be over
3/16 of an inch high.
8. Never use the MiniMag XM with Permanent Magnets on material, that has a coating zinc,
epoxy, plastic or other type of synthetic product thicker than 5 mils or .005 of an inch, as the
Machine will not adhere to the pipe or plate. Never use the MiniMag XM with Rare Earth
Magnets on material that has a coating of zinc, epoxy, plastic or other types of synthetic product
thicker than 15 mils or .015 of an inch, as the machine will not adhere to the pipe or plate.
9. Make sure the Cord (J) between the MiniMag XM Motor Control Box (13) does not become
engaged in the Wheels of the MiniMag XM causing the Machine to become disengaged from the
pipe or plate.
10. When cutting pipe or plate there must be sufficient slack in the Oxy/fuel Hoses so that the
MiniMag XM can make a square cut without becoming disengaged from the pipe or plate.
Do not allow the Torch Hoses to be dragged around the pipe or plate by the MiniMag XM .
