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 present disclosure provides welding equipment, an arc determination processing method, and an arc determination processing device, which relate to the technical field of welding. The arc determination processing method of the present disclosure is used for welding equipment, the welding equipment can send an arc determination signal, and the arc determination processing method includes: receiving the arc determination signal, and collecting the output current of the welding equipment. Determine the given voltage for the welding equipment. The given voltage is controlled not to be greater than the first threshold. It is judged whether the output current of the welding equipment has dropped. When the output current drops, it is determined that the welding apparatus enters an arcing stage.

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...
