Multifunctional electric welding system

Abstract

The invention discloses a multifunctional electric welding system comprising a control mainframe and a welding gun. The welding gun comprises a gun body. A first electrode and a demountable second electrode are arranged at the front end of the gun body, a welding-wire reel groove used for holding welding wires is arranged on the rear portion of the gun body, and a wire feeding mechanism is arranged in front of the welding-wire reel groove. The control mainframe comprises a gas delivery module, a main circuit module and a control module. The gas delivery module is connected with the welding gun through a gas delivery cable. The main circuit module is connected with the welding gun through a power cable. The control module is connected with the gas delivery module and the main circuit module respectively. The multifunctional electric welding system has functions of welding metal and repairing plastic studs, and is simple to switch during use and wide in application range; moreover, the welding-wire reel groove used for holding the welding wires and the wire feeding mechanism used for feeding the wires are arranged on the welding gun, so that wire feeding distance is greatly shortened, stability and strength of wire feeding are guaranteed, and wire feeding is not affected by changes of welding places of the welding gun.

Description

technical field [0001] The invention relates to the field of electric welding equipment, in particular to a multifunctional electric welding system. Background technique [0002] refer to figure 1 , the existing electric welding machine that uses welding wire for welding generally includes a control host 1 and a welding torch 2. The control host 1 includes a gas delivery module, a main circuit module 11, a control module and a wire feeding module 12. The welding wire 121 is arranged on the control host 1. The wire feeding motor 122 on the control host 1 is responsible for feeding the welding wire 121 . The disadvantage of this electric welding machine is that the welding wire 121 is separated from the welding torch 2. When long-distance work is required or the welding location is changed, the wire feeding distance is prolonged, which may easily lead to unsmooth or weak wire feeding, especially when using soft materials such as aluminum welding wire. There are many problems...

Problems solved by technology

The disadvantage of this electric welding machine is that the welding wire 121 is separated from the welding torch 2. When long-distance work is required or the welding location is changed, the wire feeding distance is prolonged, which may easily lead to unsmooth or weak wire feeding, especially when using soft materials such as aluminum welding wire. more problems

At the same time, if you need to adjust the wire feeding speed during welding, you must return to the control host 1 (or the external wire feeder 122) to adjust, and the back and forth operation is more troublesome.

[0003] In addition, the existing welding gun 2 has only one electrode, and the welding function is single, which needs to be developed and improved.
