ABSTRACT:
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.
