A multifunctional precision aluminum welding machine circuit

Abstract

The invention discloses a multi-function precise aluminum welding machine circuit. The multi-function precise aluminum welding machine circuit is characterized in that the multi-function precise aluminum welding machine circuit comprises a high-power insulating transformer and an auxiliary insulating transformer, and the output end of high-power insulating transformer is connected to a rectification smoothing circuit; and the auxiliary insulating transformer is connected to a full-digitization operating faceplate, a 32-bit high-speed ARM controller and the like. According to the multi-function precise aluminum welding machine circuit, a plurality of welding modes can be achieved, and a continuous precise aluminum welding mode is an original function, so that the function that a thin aluminum plate can be precisely welded is achieved, the heat input quantity is greatly lowered, and deformation of a product is small; and the easy, convenient and quick operating property can be enough to surpass laser welding repair, so that the requirements of users for a larger range are met.

Description

technical field [0001] The invention relates to welding equipment, in particular to a multifunctional precision aluminum welding machine circuit. Background technique [0002] The circuit principle of the existing aluminum welding machine is simple, and the principle of argon arc welding is used to increase the DC to AC circuit to generate AC welding pulses to weld aluminum materials. The main disadvantages are as follows: 1. The welding method is heat welding, and the product is welded at high temperature and deformed. Large quantity, easy to anneal; 2. The arcing current is large, and the thin aluminum plate within 3mm is easy to burn through, which is difficult to weld; 3. When welding thick aluminum, the current is large, and the tungsten electrode burns seriously; 4. The function is single and cannot meet the requirements. wider range of customer needs. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the pres...
