Carbon dioxide electric welding machine connecting cable and manufacturing method thereof

Abstract

The invention relates to the electric and electrical technical fields, and provides a carbon dioxide electric welding machine connecting cable and a manufacturing method thereof in order to solve the problem that connecting operation and use of a current carbon dioxide electric welding machine are inconvenient. The cable comprises a carbon dioxide supply pipe, a control signal line, a copper wire conductor strand, an inflaming retarding layer and an insulating layer. The carbon dioxide supply pipe is wrapped by the copper wire conductor strand. The copper wire conductor strand is wrapped by the insulating layer. The inflaming retarding layer is wrapped by the insulating layer. The control signal line is arranged in a space between the inner wall of the carbon dioxide supply pipe and the outer wall of the insulating layer. According to the carbon dioxide electric welding machine connecting cable, the carbon dioxide supply pipe, the control signal line, the copper wire conductor stand, the inflaming retarding layer and the insulating layer are efficiently integrated into one cable, and therefore connecting operation and use of a carbon dioxide electric welding machine are convenient.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to a carbon dioxide welding machine connection cable and a manufacturing method thereof. Background technique [0002] Carbon dioxide electric welding machine is also called carbon dioxide gas shielded welding machine. It uses carbon dioxide as a protective gas to form a carbon dioxide gas protective layer during work to isolate external oxygen and prevent the weld from being oxidized and carbonized, thereby improving the quality of the weld and making the welding plane flat. More beautiful and smooth. At present, carbon dioxide welding machines are widely used in the welding of various low-carbon steels and low-alloy steels. The carbon dioxide welding machine needs three pipe cables when it works, which are carbon dioxide gas supply pipe, control signal line and power cable. The power cable includes copper wire conductor strands, flame retardant layer and insulation...
