THE FOOT PEDLE IS NOTHING BUT A REASTAT. A REASTAT IS A WIRE WRAPPED AROUND A CONDUCTOR THE WINDINGS START OUT FAR APART AND GET CLOSER TOGETHER THE FARTHER YOU PUSH THE PEDLE DOWN . THE FAR APART WIRES ARE THE SLOW SPEED THE CLOSER ONES ARE FASTER SPEED THESE WIRES WILL WEAR OUT OVER TIME OR CORRODE OVER TIME AND CAUSE THIS PROBLEM. TRY SOME ELECTRICAL CONTACT CLEANER AND SPRAY THE FOOT PEDLE INSIDE ANY WHERE YOU CAN AND LET DRY. MOST CONTACT CLEANERS ARE NONE CONDUCTIVE AND DRY IN MINUTES
The previous solution would apply to a family machine but not to an industrial machine like the Consew 206. Older industrial machines use a clutch type motor, where the motor runs at a constant speed and the foot pedal connects the motor movement to the sewing head via a clutch like a standard transmission in a car. Newer models might use a servomotor where the foot pedal connects to a speed control inside the motor. If your machine has the clutch setup, make sure the clutch surfaces are clean and smooth and practice slipping the clutch to control speed. If you have a servomotor, there should be an adjustment screw on the motor housing that will limit speed.
