Abstract

The invention discloses an argon arc welding gas shield throttling control device. The device comprises an electric control module and a gas channel, wherein the electric control module comprises a switch power supply, a delay piece and an electromagnetic valve; the switch power supply is connected with the delay piece; the electromagnetic valve is connected with the switch power supply through the delay piece; the gas channel comprises an intake pipe, an argon storage bag, a flow meter and a gas supply pipe; the electromagnetic valve is arranged between an intake pipe and the argon storage bag; the flow meter is connected with the argon storage bag and the gas supply pipe; and the gas supply pipe is connected with a welding gun. The electric control module can be used for automatic delaycutting of argon to prevent the resource waste caused by forgetting of closing of valves; and the tightness can be guaranteed.

Description

technical field [0001] The invention relates to the field of argon arc welding gas throttling, in particular to an argon arc welding gas protection throttling control device. Background technique [0002] In order to ensure the welding quality of special metal components such as titanium, zirconium, nickel and high-grade stainless steel, inert gases such as argon must be used as welding shielding gases during the welding process. The shielding gas used in the welding torch and protective cover used in existing welding is all connected with the pipeline gas through a hose, and a flow valve is connected between the hose and the pipeline gas, and the switch of the gas source is controlled by the flow valve. If the operation needs to be interrupted during the actual welding process, the welding personnel often neglect to close the valve, resulting in the loss of protective gas, which not only increases the production cost, but also easily causes gas enrichment, which is not cond...
