Bala,

What type of weld quality problems are you having?

Porosity, cold roll, undercut, etc.?

Have you checked all of your ground connections?

Is your wire feeder mounted to the top of the robot?

Sometimes you can get "static" from a hot wire shorting out somewhere, or ground coming loose in certain positions. (ie. if you are reaching too far and stretching the wires out.)

Let me know if this helps...
