When welding a ?" in a single pass, you have to consider joint design. A quarter inch, single pass weld is certainly possible, but the heat carrying capability of the ?" plate isn't as much as the 2 inch wall pipe.
Part of the theory of a single pass, maximum thickness recommendation comes from the welders ability to provide enough heat into whatever “weldment" you are welding to achieve that amount of thickness of weld.
Paying attention to the five basic elements of Stick welding technique—Current setting, Length of arc, Angle of electrode, Manipulation of electrode and Speed of travel (CLAMS)—can significantly improve your Stick welding results. This illustrated technical article provides five steps to improve your stick welding technique,

43 Multipass welding is often employed with the submerged arc process. When plate thicknesses exceed the limitation of two pass techniques, or where inability to provide accurate joint fit-up prevents the use of high current - multiple pass submerged arc welding should be used. Where possible a split pass procedure as
