Problems solved by technology

However, this manual switch method cannot switch on and off the argon gas in time, resulting in a lot of waste of resources, and specifically the following problems:
[0003](1) When the external device is far away, it takes a long time for the operator to shut off the argon gas channel, which not only consumes time, but also causes a large loss of argon gas ;
[0004](2) When short-term arc extinguishing is required during the welding process (such as closing the external conveying device), it takes a long time to operate and close. If you still choose to open, argon will be wasted;
[0005](3) The opening and closing of argon gas delivery requires manual operation, which increases the operational complexity of the machine;
[0006](4) The external device requires a large amount of argon gas storage, resulting in a large volume of the external device, which is not conducive to moving

Description

technical field [0001] The invention belongs to the technical field of argon arc welding machines, and in particular relates to a gas circuit control system and method of an argon arc welding machine. Background technique [0002] Argon arc welding melts the base metal to form a molten pool by establishing an arc between the tungsten needle and the workpiece. In order to achieve the purpose of atomic bonding between the welded metals, the argon arc welding machine needs to continuously deliver inert gas (such as argon) as a shielding gas. The existing simple argon arc welding realizes the gas supply through the external device, and realizes the on-off of the argon gas by manually controlling the switch of the external device (gas cylinder). When the arc is extinguished and the molten pool is not solidified, continue to deliver argon to protect the weld until the molten pool is solidified before closing the external device. However, this manual switch method cannot switch o...
