Embodiment Construction
[0015] The following invention is used as a further detailed description, but not as any limitation to the invention.
[0016] Embodiment of the present invention: a method for adjusting the DC welding current. The method adopts a movable iron core in the middle of the welding transformer iron core, and adjusts the size of the eddy current to realize the current size, or adopts no movable iron core, and connects the positive pole or the negative pole in series. A resistance box, adjust the size of the resistance value to realize the size of the current.
[0017] There is no movable iron core, and the positive or negative poles are connected in series to a resistance box. The specific method of adjusting the resistance value is to conduct power-on heating and power-off cooling at the same time during pressurization, so as to prevent the joint from floating and false welding. It is most suitable for thermocompression welding, soldering and resin bonding of flexible materials and...
