PROBLEM TO BE SOLVED: To provide a controller for temperature between paths which is com pact and light-weight, is easily handleable, moreover, is easily operated, efficient ly performs a measuring operation, reliably performs temperature control in accordance with the object to be welded and contributes the reduction of man- hour and the improvement of productivity, in its turn. SOLUTION: This controller for temperature between paths is provided with a device main body 1 which has a size capable of holding with one hand, is incorporated with a circuit part 2 for temperature control and can be mounted on a position separated from a welded part of the object to be welded and a temperature sensor 4 which is connected with the device main body 1, is arranged on the welded part or on the neighboring position thereof and detects the temperature between paths of the welded part. The circuit part 2 for temperature control is provided with a setter 15 which sets the temperature between paths to be controlled, a judging means which fetches a detection signal from the temperature sensor 4, determines whether the welded part has a temperature between paths of the set temperature or more and an alarming means 17 which outputs an alarm when it is determined that the temperature between paths of the welded part is the set temperature or more by the decision means.
