The invention belongs to the technical field of arc heaters, and discloses an arc spot position and rotating speed testing device and method for an arc heater. During a test, the wireless data collector is powered by a battery and is installed on a high-voltage rear electrode of the arc heater, and the wireless data collector is electrically isolated from other parts and the ground. A plurality of thermocouples are arranged on the cathode wall surface of the electrode inner shell along the axis at equal intervals; and connecting wires of the thermocouples are connected to a wireless data collector through a cooling channel. The wireless data collector collects a temperature value, transmits the temperature value to the wireless AP of the test hall through the wireless transmitter, and then transmits the temperature value to the industrial personal computer. A worker determines the axial coordinate of the arc spot according to the obtained temperature value and determines the rotation speed of the arc spot; ca
