This may sound stupid, but I own three grinders and I admit that I really don't know how to use them properly to get the desired results. What I mean is that no one ever showed me or told me what kind of attachment to use for what.
Situation 1: Getting ready to weld. I need to clean up the metal to be welded (remove rust or contamination) and get to shiny steel. Also need a place to clamp the ground.
Situation 2: The weld is done, but I want to remove slag and clean up the weld.
Situation 3: I want to make the weld disappear after I'm done. Maybe it's a patch or a splice and I need to blend the two pieces together.
Situation 4: Prep for paint. I need to make everything smooth.
