Arc welding equipment

Abstract

The invention provides an arc welding equipment, comprising a welding torch (8), a wire feeding device for feeding wire (9) in contact with the inner surface of the tip (17) of the welding torch (8), and a welding power supply (4) for supplying a power to the tip (17) and a base metal (13), the welding power supply (4) further comprising a welding current detector (30) and a welding voltage detector (31), wherein a welding current instruction value, a welding voltage instruction value, and a wire feed speed instruction value are simultaneously displayed independently of each other and an actual welding current value, actual welding voltage value, and actual wire feed speed are selectively displayed, whereby an operator can easily find out a defective welding and determine the acceptability of welding conditions.

Description

technical field [0001] The invention relates to an arc welding device using a metal wire as a welding electrode. Background technique [0002] Conventionally, a welding current meter and a welding voltmeter are provided in a welding power source, and an operator can adjust welding conditions by observing the meters in the welding power source. Furthermore, in order to perform welding quality control and check whether there is an abnormality in the welding device, there is also a monitoring device that uses various detection instruments to detect the welding current value, welding voltage value, and wire supply speed. [0003] And, there is also a prior art disclosed in JP-A-6-238446. In this invention, a metal wire supply speed detector and a display capable of directly reading the metal wire supply speed are provided on the metal wire entry side of the supply motorized roller of the supply device, and the feedback of the metal wire supply speed is detected and displayed by...

AI Technical Summary

Problems solved by technology

[0011] In addition, since the previous arc welding robot only commanded the welding current value and welding voltage value, the metal wire supply speed commanded by the arc welding robot can only be estimated from the welding current value commanded by the arc welding robot

[0012] Since the previous welding power source and monitoring device cannot satisfy the functions of the above 1)-4) at the same time, the operator cannot judge whether the welding machine and welding conditions are abnormal
