Increase the power amount from the start, and when the first set power amount is reached, hold the first set power amount for the first time,
When the first time has elapsed, the power amount is reduced to a certain degree during the fourth time, and when the second set power amount is reached, the second set power amount is maintained for the second time, and the second time is set. A resin product to be melt-bonded is provided with a controller for controlling the heat generation amount of the heating element based on a heat pattern for stopping the melt-bonding work after a lapse of time, and by the time taken to rise to the first set power amount from the start of the melt-bonding work The controller is connected to the resin product to be melted with a temperature sensor that detects the gap between the products and the temperature of the outside air.The heat pattern is also based on the gap between the products to be melted and the outside air temperature. In addition, the temperature of the resin product to be melted is adjusted to a temperature equal to or higher than the melting point temperature and equal to or lower than the deterioration and damage temperature of the resin with the first set electric power.

脂を適正に定着させ得るものである。[Operation] Therefore, in an electric fusion welding apparatus for a resin product that supplies electric power to a heating element provided in a resin product to be fused and melts the resin at the joint portion, the electric power amount is increased from the start of the fusion welding work. When the first set power amount is reached, the first set power amount is maintained for the first time, and when the first time has elapsed, the power amount is reduced by a certain degree for the fourth time, and the second set power amount is set. When the temperature reaches the second set amount of power, the controller keeps the second set amount of power for the second time and stops the welding operation when the second time elapses. The molten resin at the joint of the resin-coated product can be fixed properly.
