Digitized inverter welding machine

Abstract

The invention relates to the technical field of electric welding machines, in particular to a digitized inverter welding machine which comprises a preceding public power supply circuit, an auxiliary power supply circuit, a main control circuit, a welding machine control circuit, a wire feeder control circuit and a wire feeder motor connected with the wire feeder control circuit. Current is divided into three paths after passing through the preceding public power supply circuit, and the three paths of current respectively enter the wire feeder control circuit, the welding machine control circuit and the auxiliary power supply circuit. According to the digitized inverter welding machine, the wire feeder control circuit is connected with the preceding public power supply circuit, so that the wire feeder control circuit and the welding machine control circuit use one and the same power supply, an additional power supply is not needed to be arranged, and meanwhile the input voltage of the wire feeder control circuit is lowered, so that an insulated isolation part is not needed to be additionally arranged in the wire feeder control circuit, the whole size and mass are lowered, production and selling costs are reduced, and daily production operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric welding machines, in particular to a digital inverter welding machine. Background technique [0002] At present, inverter welding machines have been widely used in the welding operations of various non-ferrous metals and their alloys in various industries. The inverter welding machine is favored by users for its light weight, small size, less copper and steel consumption during production, remarkable energy saving effect and excellent welding process performance. The digital multifunctional inverter welding machine uses a digital control chip to control the welding power supply and automatic wire feeding device, integrating multiple welding processes into one, realizing the value-added application of one machine with multiple functions, and improving the automation of welding. The automatic wire feeding part of the existing digital multifunctional inverter welding machine also adopts the mains p...

AI Technical Summary

Problems solved by technology

Since the circuit of the automatic wire feeding part connects its primary side circuit to the power grid, and because the voltage value of its output is very different from the voltage value of the power grid at the input end, the circuit must be provided with insulating and isolating materials for voltage isolation, and, A separate power supply is provided for the circuit of the wire feeding part, which makes the whole machine bulky and heavy, increases production and sales costs, and is not conducive to mobile operations
