The Cornwell Quality Tools Heavy Duty Single/Dual Bottle Welding Cart, No. MMWUWC4, can be used to hold portable wire welders, plasma cutters, and TIG welders along with the bottle of shielding gas needed for that application. Its unique cylinder rack allows users to configure it to carry one bottle of gas up to 10" in diameter and up to 300 cu. ft.; or two bottles of gas up to 7-1/2" in diameter or 150 cu. ft. each. Additionally, users can also hold two separate welders, a welder and a plasma cutter, or they can use as a power source and feeder cart.
