[QUOTE="nathon918, post: 4093188, member: 86827"] the 6010 and 7018 both good for the work, but depending on the size of the material your welding, anything over 6" square , id be pre-heating the material before welding, not just where your welding, but all around it. use a rosebud, or a propane weed burner works pretty good in a pinch usually anything over 3/4" material we pre-heat, all of the material around the weld will act as heat sink and pull the heat right out of the weld, causing it to cool too fast and usually cracking the weld . small parts dont usually need pre-heating because the weld heats the material up pretty good [/QUOTE]
