What welding rods do you stick welders use? For all purpose or what do you use for certain tasks? At work we use mainly 7018 for structural applications, sometimes 7014. We got a new guy and he prefers 6011. Says it is a penetrating rod, I have never used them myself. When I get ready to make a bumper for my xj I want to use what is ideal, and if its something I'm not used to, want to get a few rods burned so I can make it look good.
