Problems solved by technology

[0004] However, due to the influence of cable voltage and some interference signals, there is a deviation between the output voltage and the actual arc voltage, and the judgment result using the output voltage is prone to errors, that is, misjudgment
It may appear that the arc control process starts at the short-circuit stage, which may easily cause arc disorder, wire jacking, wire collapse, or abnormal arc burning.

Abstract

The invention provides a welding device and a combustion arc determining treatment method and device and relates to the technical field of welding. The combustion arc determining treatment method is used for the welding device. The welding device can give out a combustion arc determining signal. The combustion arc determining treatment method includes the steps that the combustion arc determining signal is received; an output current of the welding device is acquired; a given voltage of the welding device is determined; the given voltage is controlled to be not larger than a first threshold value; whether the output current of the welding device descends or not is judged; and when the output current descends, it is determined that the welding device enters a combustion arc segment.

Description

technical field [0001] The present disclosure relates to the field of welding technology, in particular, to a welding device, an arc burning determination processing method, and an arc burning determination processing device. Background technique [0002] Welding, as a common joining process, is widely used in industry. Among them, arc welding is a relatively common welding method. For arc welding using short-circuit transition, it usually needs to go through a short-circuit stage and an arc-burning stage in sequence. At present, most arc welding equipment adopts waveform control technology, that is, according to different welding wires and shielding gases, different control methods are adopted in the short-circuit stage and the arc-burning stage. Therefore, it is very important to accurately judge the timing of entering the arcing stage from the short circuit stage. [0003] In the prior art, since the arc voltage is difficult to measure directly, the output voltage of th...
