the design of the protection device. the equipment is beijing (Gouging) on a welding torch, the torch is more detailed than the air hose, air hose, to protect all of the spring festival, to be the diameter of the coil spring to the protection device installation according to the character of welding, torch angle, in order to properly adjust the air hose hole when the coil spring to the air hose of elastic support and maintenance outsourcing, with the change in the air is almost no slow twists and turns can be induced to have... the air tube has been installed in the air and prevent the damage of a circuit, and the welding is efficiently can be used to extend the service life of the air also can be an air hose protection device and equipment are always on the welding torch.;according to this design, the circuit is equipped with the air and the air jet and the banner and electrode. the electrode of the torch in the above ontology. it is the spring of the elastic support on the device, the torch of the ontology with the operation button switch the new the feast for the eyes of the welding torch, the torch of the ontology, but the twists and turns in the city almost no changes are slow in the twists and turns of the outsourcing, the elastic support of the coil spring protection device has been installed and the characteristics. air hose protection device. the welding equipment is provided and the value.
