Welding Rod Keeps Sticking. The main reason for sticking is the high current welding rod flow and a higher melting point of the welding rod. Most notably this E7018 stick welding rod provides exceptionally clean welds enabling you to keep splattering to a minimum.
Other welding characteristics such as arc performance may be affected as well. If youre welding with amperage set too low your electrode will be especially sticky when striking an arc the arc will keep going out while maintaining the correct arc length or the arc will stutter. When the stick is pulled away from the workpiece that creates an arc.
A low hydrogen rod coating that has absorbed moisture may result in a weld with hydrogen induced cracking.
The slang term Stick Welding comes from the stick type of electrodes used to weld like in this picture. This compound is what vaporizes and in the process protects the weld bead from contamination by moisture and air. Arc welding rod sticks to the parent metal due to low amperage values Low current. If welding rod melts after the melting of base metal it causes sticking.
