it's not dirt that was the problem... it was wind... even at that it's real rare to use anything but a heliarc root on a powerhouse of any kind... wouldn't have happened there if it had belonged to a utility provider... this was a co-gen supporting a steel mill...
actually, lincoln rod is rarely used on any powerhouse job... esab is the norm across north america...
and even at that we used 6010 only to test... 7010 and 8010 on the boiler depending on location... the weld procedure is identical so the 6010 is used to test... and it really only works well with NDE... only ever so rarely do they bend a "5p" root....
it's just a commonly used mis-statement that we use "5p"... we (however wrongly)classify all of the --10 quikstiks as 5p rods...
