Embodiment Construction

[0009] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, there is an engine ① installed in the digital generator welding machine, a three-phase permanent magnet generator ② is installed on the output shaft of the engine and outputs a set of three-phase intermediate frequency high-voltage signals; the three-phase rectification and voltage stabilization module ③ is connected with the three-phase permanent magnet generator The three-phase medium-frequency high-voltage signal passes through the three-phase rectification and stabilization module to generate a DC high-voltage power supply; the DC-AC conversion module (generator part) ④ is connected to the three-phase rectification and stabilization module, and a part of the DC high-voltage power supply splits through DC and AC The conversion module (generator part) generates a high-voltage AC signal; the LC low-pass f...

Abstract

The invention discloses a digital generating electric welding machine which is a new application integrating a generator and an electric welding machine. The digital generating electric welding machine comprises an engine, a three-phase permanent magnet generator, a three-phase rectifying voltage stabilizing module, a DC / AC converting module (as part of the generator), a LC low-pass filter, a DC / AC converting module (as part of the electric welding machine), a high-frequency transformer, a DC / AC rectification module and a welding arc generator. The digital generating electric welding machine is characterized in that a DC signal outputted through the three-phase rectifying voltage stabilizing plate is simultaneously inputted into the DC / AC converting module (as part of the generator) and the DC / AC converting module (as part of the electric welding machine), thereby simultaneously outputting an AC (220V, 50Hz) and a DC arc. The advantages of the digital generating electric welding machine are that the machine is small in size, light in weight and easy to carry, enables to save much copper material, improve efficiency and save fuel, and helps to output stable welding arc and use the AC arc and welding arc simultaneously.

Description

technical field [0001] The invention relates to a digital power generation electric welding machine, especially a digital power generation electric welding machine that can output AC voltage (220V, 50Hz) and DC arc at the same time, which belongs to the highly comprehensive series of engines, generators, power electronics, automatic control, microelectronics, etc. technical field. Background technique [0002] Traditional electric welding machines need to be connected to an external AC power supply, which is very inconvenient to use without the support of mains power. When used on construction sites or on ships where welding is required, it is often necessary to pull wires to conduct electricity, which poses a great safety hazard. The traditional electric welding machine is single-use and can only be used for welding. In some places far away from human habitation, such as the field or desert, it is necessary to carry a generator and electric welding machine to meet the deman...
