I usually rest the side of the heel of my palm on the workpiece or on something stable if possible. Sometimes there isn't any thing to rest on close to the weld, and an elbow up against the wall or even just tucked into your side o on your hip bone can help.
I have a 200DX. You note 200 LX. Is that correct (LX)? If do, where did you get it?

Any day on a motorcycle like this that ends just needing parts and labor is a good day.
