Abstract

In the energy-storing multifunctional welding machine, the charge voltage of the energy-storing capacitors is selected via controlling the on-off of the AC zero-crossing solid relay, instead of voltage regulation of main transformer. At the same time, one sensitive and reliable voltage monitoring negative feedback system is designed to ensure the DC voltage fluctuation of energy-storing capacitors less than 0.2 %. The energy-storing multifunctional welding machine includes energy-storing capacitors, proportional voltage regulating system, welding output loop with thyristor switching assembly,voltage monitoring negative feedback system, thyristor triggering control system and power supply system. it may be used with various kind of welding guns.

Description

technical field [0001] The invention relates to an energy storage type welding machine, more specifically to a non-transformer energy storage type multifunctional welding machine. Background technique [0002] Energy storage welding machine is a new efficient welding method. The basic principle is: through a group of charging capacitors, the contact of two metal objects is discharged instantaneously, and the contact is quickly heated to a molten state, and then the two metal objects are welded together under a certain pressure. [0003] At present, there are energy storage type stud welding machine and energy storage type heat preservation nail welding machine, etc., the former discharges in the form of arc, while the latter discharges in the form of resistance. The welding machine consists of three parts: power supply, control system and welding torch. The working principle of the power supply of the pre-contact and reserved-gap capacitor discharge stud welding machines i...
