This sturdy steel cart is designed to hold 2 units, plus 2 bottles of shielding gas and the consumables. The top shelf is designed specifically to allow access to the side panel on MIG welders if needed. Works great for most TIG and stick welders, as well as plasma cutters too. You can easily adapt this cart to almost any 2 welders. There is room for up to 6 tubes of TIG rod, plus 3 hooks to coil and hang your hoses or cables.
