The present invention is a bilevel, cantilevered, welding cart with a rear cylinder rack and angled top platform. The cart frame is of a one piece heavy gauge steel that is capable of transporting in excess of 600 pounds. The front caster wheels and rear axle are welded to the frame leaving only the rear wheels to be attached. It has a single rear pillar support that can be offset in front of the gas cylinder support to allow easy connection of the gas, water air and or power lines to the welding unit. The gas cylinder support positions the weight of the gas cylinder adjacent the rear axle to prevent tipping.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is as follows: 1. A bilevel, cantilevered platform, steel welding cart having a one piece welded frame capable of supporting at least 600 pounds comprising: a lower, generally planar platform having an outer, peripheral lip; an upper, generally planar platform having an outer, peripheral lip, a single telescoping support pillar having an upper and lower end, and holding said upper platform in an angled, spaced configuration with respect to said lower platform; at least one rear gas cylinder support plate; at least one rear gas cylinder stabilizing plate; at least one gas cylinder retaining chain; two rear pneumatic tire wheels; a rear wheel axle; and two front caster wheels having a metal caster mounting plate, wherein said upper platform comprises a rectangular frame having a front and rear end upper member and a first and second side upper member made from at least 3/16 of an inch thick angle steel, and having a first angle steel upper crossmember adapted for welded connection between said first and second side upper members so as to be adjacent and in a substantially parallel and spaced configuration with said rear end upper member, and wherein said first angle steel upper crossmember and said rear end upper member are welded about an outer periphery of said upper end of said support pillar so as to maintain said upper platform at an angle between 1 and 10 degrees in relation to said lower platform, and wherein a generally planar steel grating is welded to said first and second side upper members so as to form a support surface. 2. A bilevel, cantilevered platform, steel welding cart having a one piece welded frame capable of supporting at least 600 pounds comprising: a lower, generally planar platform having an outer, peripheral lip; an upper, generally planar platform having an outer, peripheral lip, a single telescoping support pillar having an upper and lower end, and holding said upper platform in an angled, spaced configuration with respect to said lower platform; at least one rear gas cylinder support plate; at least one rear gas cylinder stabilizing plate; at least one gas cylinder retaining chain; two rear pneumatic tire wheels; a rear wheel axle; and two front caster wheels having a metal caster mounting plate wherein said upper platform comprises a rectangular frame having a front and rear end upper member and a first and second side upper member made from at least 3/16 of an inch thick angle steel, and having a first angle steel upper crossmember adapted for welded connection between said first and second side upper members so as to be adjacent and in a substantially parallel and spaced configuration with said rear end upper member, and wherein said first angle steel upper crossmember and said rear end upper member are welded about an outer periphery of said upper end of said support pillar so as to maintain said upper platform at an angle between 1 and 10 degrees in relation to said lower platform and wherein said upper platform further comprises a second angle steel upper crossmember adapted for welded connection between said first and second side upper members so as to be in a substantially parallel and spaced configuration adjacent with said front end upper member serving as a support for the feet of a welding or similar unit and wherein said lower platform further comprises a rectangular frame having a front and rear end lower member and a first and second side lower member made from at least 3/16 of an inch thick angle steel, and having a channel steel lower crossmember adapted for welded connection between said first and second side lower members so as to be in an adjacent and substantially parallel and spaced configuration with said rear end lower member, and wherein said channel steel lower crossmember is welded about an outer periphery of said lower end of said support pillar and wherein said lower platform further comprises an angle steel lower crossmember adapted for welded connection between said first and second side lower members so as to be in a substantially parallel and spaced configuration with said front end lower member, and wherein said angle steel lower crossmember and said front end lower member serve as mounting points for welding said front caster wheel mounting plates. 3. The bilevel cantilevered platform steel welding cart of claim 2 wherein said lower platform first and second side lower members have orifices defined therein through which said rear wheel axle protrudes. 4. The bilevel cantilevered platform steel welding cart of claim 3 wherein said rear wheel axle is welded to said rear end lower member. 5. The bilevel cantilevered platform steel welding cart of claim 4 wherein said first and second side upper members have at least one hook extending therefrom. 6. The bilevel cantilevered platform steel welding cart of claim 5 wherein said rear gas cylinder stabilizing plate is welded to said rear end upper member and has a vee shaped configuration thereon so as to cradle a gas cylinder and prevent lateral movement thereof. 7. The bilevel cantilevered platform steel welding cart of claim 6 wherein said chain has a first end permanently affixed to said gas cylinder stabilizing plate and a second end that can be temporarily affixed to said gas cylinder stabilizing plate so as to further secure a gas cylinder. 8. The bilevel, adjustable height, cantilevered platform, steel welding cart of claim 7 wherein said telescoping support pillar comprises: an inner steel tube; an outer steel tube; a mechanical fastener; wherein said inner steel tube has an outer diameter that is dimensionally smaller than an inner diameter of said outer steel tube yet allows said tubes to operate in sliding engagement, and wherein said inner steel tube has at least one first orifice therethrough and said outer steel tube has at least one substantial similar second orifice therethrough such that said orifices are alignable and through which said mechanical fastener may pass.
