> Weld positioner and high frequency interference

We are rooting up carbon steel pipe in a weld positioner with a EWM, Q300 GMAW welder, using their pipe solutions program but, as soon as you start turning the job using the foot pedal, we get high frequency interference in the weld pool. Obviously, its coming from the electric motor (the positioner is new) but the manufacturer of the manipulator has never had or hear of any problems like this before. With conventional GMAW, this doesn't happen.
Has anyone on here had similar problems and if so, how did you rectify it?

Thanks Bb
