Ø The machine has a forward/reverse directional toggle switch located on the main control panel.
o NOTE: There is also a neutral position for this switch in between the positions.
Ø The variable speed switch will increase of decrease the machine speed. 0 symbolizing no
movement and 10 symbolizing fast movement.
Ø The power control box cord connection point is where the black power cord plugs in from the
control box.
o NOTE: Make sure to line up the half round notch in plug with the half round piece in the
plug input.
Ø The control box converts the AC current coming in from external power to DC, which is used by
the main machine motor.
o The main power control box has a power indicator light (which indicates the control box
has AC power connected), an electrical fuse and a main on/off switch.
o CAUTION: Do not remove the fuse unless the power control box is disconnected from
the power source.
§ When the main on/off switch is in the “on” position it is sending DC power to the

Ø Ensure the work surface and machine are free of debris, oil, etc.
o NOTE: The machine will deviate from the cut or potentially fall if the material is not clean
(bare) and seamless.
Ø Carefully place machine at the start of the cut ensuring the wheels gently make contact with the
cutting surface. If cutting pipe, it is generally easiest to start at the top of the pipe.
Ø Select appropriate size torch tips for the application. Install tip.
Ø Select cutting angle.
Ø Connect the control box cord connection plug.
o CAUTION: Ensure all power lines are run in a manner not to cross paths with cutting
flame or cut material work pieces.
Ø Securely fasten the plug into the machine and lock in using the plug screw.
Ø Select the neutral position in the machine directional toggle switch (center position).
Ø Plug the cord on the power control box into the external power source.
Ø Connect applicable gas lines.
o Make certain they are properly secured and there are no leaks. It is highly recommended
