first off if this is for heavy equipment with a good amount of weight on the weld the go with the 7018 1/8th inch rod. set heat a bit hot and reduce it if you need to. on the verticle welds start at the bottom and work up. chip the slag away at every stop to check the progress. you may need to adjust the heat as you go, or simply speed up or slow down. you will want to weave from left to right so the weld is about 5/8" wide. before you start grind the old weld to remove existing slag. you may need a couple passes. if so grind clean and smooth. good luck.
