What is the operation sequence when the gas welding torch is ignited?

When the welding torch is ignited, the oxygen regulating valve should be opened first, and then the acetylene valve should be opened. On the contrary, when the torch backfires and explodes, the nozzle should be extinguished, cooled with cold water, and then dredged with steel.

When the operator picks up the welding torch, it can automatically turn on, and the gas (acetylene) and oxygen synchronously generate a DC pulse and spark for 5 seconds, which can be used by aiming at the igniter. So as to avoid the gas welding gun being in a normally open state or frequently closing the gun in the production line;

It can save energy, improve production and working environment, improve product quality, realize scientific and refined management, and has the advantages of convenient overall operation, small volume, stable and reliable control circuit, and the power consumption of the intermittent on-off controller of the gas welding torch is less than 8 watts.

Extended data:

It consists of a gun body, an air supply device and an ignition mechanism, and is characterized in that the front seat of a large sleeve made of a hollow tube and a small sleeve are connected into a rod shape, the tail end of the small sleeve is fixedly connected with a fire cap, and the air supply device and the ignition mechanism are installed in the large sleeve;

Press down the gas box from the back seat, open the gas outlet valve and start the ignition mechanism to spray and burn in the nozzle in the fire cap, and use the back seat to adjust the flame size for brazing or gas cutting;

The fire cap connects the fire chamber and the welding head for welding operation, with simple structure, convenient operation, beautiful and compact appearance, including all the advantages of micro gas welding tools, and adopts the valve of commercial lighter, which is convenient for refueling, carrying and using.
