I have to weld a back actor on a jcb . I have a frounis transpocket 150 . I want to clean up the crack and all around it. I was going to do the root pass with 6010 and Cover that with either 6013 or 7018. I have a 225 amp mig as well but I'm not sure if it would be upto the job. Any advice on other rods I could use
