Mathey Dearman MiniMag XM - Manual (Page 11)

Warning: Always use a safety cable, rope or belt with MiniMag XM to avoid injury or damage to
the Machine should it become disengaged from the pipe. Never use a Safety Chain as the Chain
may become engaged in the Wheels of the MiniMag XM causing the machine to become
disengaged from the pipe or plate.
4. Check both Socket Head Allen Screws of the Torch Holder (6) to ensure these are loose enough for
the Machine Fuel Torch (A) to slip into the torch holder assembly (6). Use the 4mm Allen Wrench
provided with the MiniMag XM to loosen or tighten the
Socket Head Allen Screws.
5. Install the 12‐inch Machine Fuel Torch with Rack (A) into Torch Holder Assembly (6).
6. Tighten the Socket Head Allen Screws with the 4mm Allen Wrench provided, until sufficient
pressure is applied to the Torch to hold it in position in Torch Holder
Assembly (6).
7. Connect the Oxy/fuel Hoses to the Torch per the Torch Manufacturer's Operating Instructions.
Make sure the Oxy/fuel Hoses are long enough to allow the Machine to make the complete cut.
Note: When cutting pipe the Hoses of the Machine Torch should be wrapped one (1) full turn
around the pipe to help support the weight of the Hoses. 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 goes around the pipe.
Warning: When cutting pipe or plate, make sure there is sufficient slack in the Oxygen and Fuel
Hoses so that the MiniMag XM will make a square cut and does not become disengaged from the
pipe or plate.
Note: The MiniMag XM should never drag the hoses around the pipe or along the plate.
Note: Make sure the Electrical Cord (J) of the MiniMag XM Motor Control Box does not become
engaged in the Wheels of the MiniMag XM , causing the Machine to become disengaged from the
pipe or plate.
Note: Make sure there is enough slack in the Electrical Cord (J) to accomplish the full length of the
cut.
8. Light the Fuel Machine Torch and adjust the flame per the Torch Manufacturer’s Operating
Instructions.
Warning: Never use a cigarette lighter to light the Cutting Torch.
9. Turn the Ratchet Handle of the Torch Holder Assembly (6) counterclockwise and adjust the Torch to
the desired bevel angle. Once the Torch is set to the desired bevel angle, turn the Ratchet Handle
clockwise to hold the Torch at that bevel angle.
10. Adjust the Torch Tip to material distance per the Torch Manufacturer's Operating Instructions.
Preheat the material per the Torch Manufacturer's Operating Instructions.
11. Turn the Oxygen‐Cutting Valve of the Fuel Torch to the cutting position to penetrate the material
per the Torch Manufacturer's Operating Instructions.
12. Move the Forward and Reverse Switch (F) in the direction the MiniMag XM should travel.
Note: The Unit Directional Control Switch (F) should always be moved to the STOP position for at
least one full second before changing motor direction.
13. Slowly rotate the Rheostat (G) clockwise until the desired cutting speed is achieved.
Note: Refer to the Manufacturer’s Oxygen Fuel Cutting Reference Chart for cutting trouble‐
shooting illustrations.
