a rectangular container having a frame and reinforcement located at a bottom thereof, where the frame and reinforcement is square tubing; the rectangular container permanently affixed to a top of the axle-hub combination, wherein the rectangular container is configured to be a predetermined size that holds bottles of gas used in welding, wherein the bottles are held in a vertical position; and a tongue attached to the rectangular container; and a pair of wheel fenders located on lateral sides of the rectangular container with a fork slot mounted above or level with each of the wheel fenders for lifting the trailer system. ### Claim 2 (depends on 1) The system of claim 1, further comprising: the trailer system being narrow enough to fit through garage doors. ### Claim 3 (depends on 1) The system of claim 1, further comprising: an interior compartment of the rectangular container having a rolled flat bar located such that the various bottles are forced to be balanced over the axle-hub combination, thus preventing mis-loading or mis-locating within the rectangular container. ### Claim 4 (depends on 1) The system of claim 1, further comprising: a jack tongue side mount connected to the tongue; a swing back dolly wheel attached to the jack tongue side mount. ### Claim 5 (depends on 4) The system of claim 4, further comprising: the jack tongue side mount being foldable thereby providing an option of reducing a length of a neck of a trailer. ### Claim 6 (depends on 4) The system of claim 4, further comprising: the swing back dolly wheel having a wheel lock mechanism deployable in a stationary position that prevents the trailer system from rolling down sloped ground. ### Claim 7 (depends on 4) The system of claim 4, wherein the swing back dolly wheel comprises a neoprene caster wheel. ### Claim 8 (depends on 1) The system of claim 1, further comprising: lights, an electrical wire harness, and a tow ball tongue. ### Claim 9 (depends on 1) The system of claim 1, further comprising: one or more anti-tip back stops attached to the frame and reinforcement. ### Claim 10 (depends on 9) The system of claim 9, further comprising: the one or more anti-tip back stops having a rectangular shape with a tip attached thereto. ### Claim 11 (depends on 9) The system of claim 9, further comprising: the one or more anti-tip back stops being positioned at one or both sides of a swing ramp. ### Claim 12 (depends on 1) The system of claim 1, further comprising: a plurality of reinforcing stiffeners located in upper corners of the rectangular container. ### Claim 13 A method of manufacturing a torch cart, comprising: bending steel sheets of a predetermined size and width to form a rectangular container for holding large heavy bottles in a vertical position; mounting a pair of wheel fenders on lateral sides of the rectangular container, said lateral sides of the rectangular container each further including a respective fork slot mounted above or level with each of the wheel fenders for use in lifting the torch cart by forks from a fork lift; preparing an axle-hub mechanism for accepting the rectangular container thereupon; positioning the rectangular container upon the axle-hub mechanism so that a center-of-gravity of an unloaded rectangular container is directly above the axle-hub mechanism; and permanently fastening the rectangular container upon the axle-hub mechanism. ### Claim 14 (depends on 13) The method of claim 13, further comprising: prior to the above step of positioning the rectangular container; positioning square tubing around a bottom of the rectangular container; the square tubing acting as a frame and reinforcement for the rectangular container. ### Claim 15 (depends on 13) The method of claim 13, further comprising: wherein the step of permanently fastening is achieved by welding. ### Claim 16 (depends on 13) The method of claim 13, further comprising: wherein the step of permanently fastening is achieved by a combination of welding and boring/tapping steel bolts. ### Claim 17 (depends on 13) The method of claim 13, further comprising: attaching a towball tongue to the rectangular container, wherein said towball tongue is to be attached to a motorized vehicle comprising a truck or a car; and attaching a tongue mechanism to the towball tongue. ### Claim 18 (depends on 17) The method of claim 17, further comprising: incorporating a jack-tongue side-mount swing-back dolly into the tongue mechanism. ### Claim 19 (depends on 17) The method of claim 17, further comprising: attaching the tongue mechanism to the towball tongue by bolting. ### Claim 20 (depends on 13) The method of claim 13, further comprising: attaching a rolled flat bar to the rectangular container such that the bottles are forced to be balanced over the axle-hub mechanism.
