Automatic TIG welding argon feeding and stopping control device

Abstract

The invention relates to an automatic TIG welding argon feeding and stopping control device which comprises a solenoid valve, a gas outlet pipeline, a gas inlet pipeline, aerial sockets I and an aerial socket II. The solenoid valve is mounted in a shell of a welding machine remote controller, the gas outlet pipeline and the gas inlet pipeline are connected to an inlet and an outlet of the solenoid valve respectively, and the aerial sockets I and the aerial socket II are mounted on the shell of the remote controller and an electric welding machine shell respectively. One end of an argon outlet pipe is connected to a pipe opening of the gas outlet pipeline, the other end of the argon outlet pipe is connected to a magnetic nozzle of a welding gun, the solenoid valve is controlled to be connected by a welding machine power source through a welding machine power source wire, a remote controller wire and a solenoid valve power source wire after a high-frequency switch of the welding gun is pressed, and the gas outlet pipeline and the gas inlet pipeline are connected. At the moment, the supply of argon to a welding machine can be ensured. After the welding machine is stopped and the high-frequency switch of the welding gun is released, the connection between the gas outlet pipeline and the gas inlet pipeline is broken off through the solenoid valve, and automatic gas stopping is achieved at the moment. The argon is prevented from running off for nothing, and economic benefits are improved.

Description

technical field [0001] The invention relates to a control device for stopping argon gas feeding for TIG welding. Background technique [0002] In the welding construction of electric power construction, the pressure-bearing pipeline needs to be welded by argon-electricity combined welding or all-argon welding. In most cases, the construction site is relatively far away from the welding machine and argon gas cylinder (argon supply point), and most of them are located at high altitudes, which is inconvenient to walk. The usual practice is to use the remote control provided by the welder manufacturer to adjust the welding parameters. The argon gas is directly connected to the argon arc welding torch from the argon gas cylinder (argon supply point), which cannot realize the function of automatically sending and stopping argon gas designed by the welding machine. If the on-off of argon must be done manually, either close the argon valve or close the valve of the welding torch, a...

Problems solved by technology

In most cases, the construction site is relatively far away from the welding machine and argon gas cylinder (argon supply point), and most of them are located at high altitudes where walking is inconvenient

The usual practice is to use the remote controller supplied by the welding machine manufacturer to adjust the welding parameters. The argon gas is directly connected to the argon arc welding torch from the argon gas cylinder (argon supply point), which cannot realize the function of automatically sending and stopping argon gas designed by the welding machine.

If the on-off of argon gas must be manually operated, either close the argon gas valve or close the valve of the welding torch, and in many cases the welder does not close or forgets to close the valve, resulting in unnecessary waste of argon gas

Especially for projects in remote areas, the price of argon gas is high, and the losses caused are also large
