Problems solved by technology

[0003] The current double-pulse MIG / MAG welding machine will produce pores during welding. There are many reasons for the pores, the most common of which is that the temperature of the welding torch is not high enough and the air around the double-pulse MIG / MAG welding machine still has moisture. In addition, too fast cooling at the welding interface will also form welding pores

Abstract

The invention discloses a double-pulse MIG / MAG welding machine capable of reducing the number of welding air holes. The welding machine comprises a double-pulse welding machine. A welding line is arranged on one side face of the double-pulse welding machine, the welding line is connected with the side face of the double-pulse welding machine through a plug and a socket, a handheld handle is arranged on the top of the welding line, a fixing ring is arranged on the top of the handheld handle, a temperature sensor is arranged in the fixing ring, a display screen is arranged on one side face of the fixing ring, a welding gun is arranged on the top of the fixing ring, a heating ring is arranged in the welding gun, the welding gun is hollow, the heating ring is embedded into the inner surface ofthe welding gun, air outflow pipes are arranged on the two adjacent faces of the side face, where the welding line is located, of the double-pulse welding machine, the air outflow pipes are hollow, electric heating wires are arranged in the air outflow pipes, the electric heating wires are embedded into the inner walls of the air outflow pipes, and a first exhaust fan and a second exhaust fan arearranged in the double-pulse welding machine. Waste heat of the double-pulse welding machine is utilized, and the number of the welding air holes generated during welding is further reduced.

Description

technical field [0001] The invention relates to the technical field of double-pulse MIG / MAG welding machines, in particular to a double-pulse MIG / MAG welding machine which reduces welding porosity. Background technique [0002] With the development of society, there are more and more applications for double-pulse MIG / MAG welding machines. [0003] The current double-pulse MIG / MAG welding machine will produce pores during welding. There are many reasons for the pores, the most common of which is that the temperature of the welding torch is not high enough and the air around the double-pulse MIG / MAG welding machine still has moisture. In addition, too fast cooling at the welding interface will also form welding pores. [0004] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0005] The purpose of the present invention is to solve the shortcoming in the prior art, and propose a kind of double-pulse ...
