The grains are no longer cutting into much weld metal, which in turn reduces spark production. Similarly, if you don't push hard enough, the grains don't fully engage the workpiece, so they don't remove much weld metal with every disc rotation. 4. Listen to the grinder. A grinder's sound can indicate similar problems.
