A combination of a protective case enclosing a plasma cutter , the combination comprising: a protective case forming a chamber, the protective case having a inner bottom surface with a formation formed thereon and a lid having an open and closed position enclosing a chamber, the lid having an inner lid surface having a formation formed therein; a plasma cutter within the chamber, the plasma cutter having a bottom surface interfitting with the formation on the inner bottom surface to securely retain the plasma cutter within the protective case; and wherein the formation formed on the inner lid surface interfits with the CNC plasma cutter when the lid is in the closed position to prevent lateral or vertical movement of the plasma cutter by sandwiching the plasma cutter between the formation on the inner lid surface and the formation on the inner bottom surface of the protective case.

Therefore, in accordance with the present invention, there is a protective case for a plasma cutter that allows the plasma cutter to be stowed in the protective case with no manipulation needed to put the plasma cutter into a particular orientation. That is, the plasma cutting machine is stored in the protective case in the same orientation as it is used. In addition, the aspect ratio i.e. height to width can be nearly equal to the aspect ratio of the plasma cutter itself.

The protective case with the plasma cutter contained therein can be readily carried by a user and the cnc plasma cutting machine is securely retained within the protective case by being sandwiched between a special formation formed on the inner surface of the lid and the inner surface of the bottom of the case.

There is also space provided for the stowage of an accessory box and plug accessories and those components are also specially securely retained within the protective case so as to prevent their movement therein.

These and other features and advantages of the present invention will become more readily apparent during the following detailed description taken in conjunction with the drawings herein.

There is an increased risk of damage to the plasma cutter

Plasma cutting is a process in which an electric arc is used for cutting or gouging a workpiece. The plasma cutter is generally contained within a housing and provides output power to a pair of cables that extend from the plasma cutter apparatus. One of the cables has a torch that is located at the outer end of the cable and the other cable has a work clamp at its outer end that is adapted to be attached to the workpiece.

The CNC plasma cutter apparatus is designed to be a portable unit, that is, the plasma cutter can be carried by a person from location to location. Basically, the new inverter based plasma cutters now achieve the portability of other industrial power tools. With such portability, however, there is an increased risk of damage to the plasma cutter which increases the importance of protection in transport and storage.

While there are protective cases used among highly portable power tools, such as drills, saws and the like, at the present, protective cases are not widely used with plasma cutting machines. Protective cases have also been used on portable welding equipment, however, these protective cases for that purpose require manipulation of the power source from a natural vertical position to a horizontal position. In addition, the weld and ground cables for such welding equipment must be detached from the power source and be deliberately arranged in a specific manner into a storage position.

With a plasma cutter, the reorientation of the cutter is made more difficult by the comparative size, weight and amount of cabling that needs to be manipulated, as compared with standard power tools.

Accordingly, it would be advantageous to have a protective case that requires little, if any, cable and power source manipulation in order stow the plasma cutter therein. In addition, it would be advantageous to have a protective case that requires minimal power source and cable manipulation for stowage in the protective case, while closely matching the aspect ratio of the plasma cutter to maximize space efficiency.
