BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inverter arc stator welding machine, and more particularly, to an inverter arc stator welding machine having a structure capable of joining bars and rods in reinforcing bars or general machine works by stud welding.

In general, welding is widely used in various industrial fields such as construction, shipbuilding, plant, and other industrial machinery manufacturing plants. Arc stud welding, which is commonly used, is a method in which studs such as bolts, pins and pipes are inserted and welded in a short time using an arc stud welding machine, and an arc is generated between the ends of the bolt and the shaft and the base metal Which is a method of electric welding.

Conventional arc stud welding is a method in which a positive electrode (+) and a negative electrode (negative electrode) are melted by arc heat at a high temperature to melt the material, and the arc stud welder used for arc stud welding is a welding gun After the stud is positioned (inserted) into the end tip, a stud such as a welding rod or a fusible material is closely attached to the part to be welded, and at the same time, the switch is actuated so that the end of the stud and the base material are melt- Here, the principle that the studs are welded is that welding is performed by an arc generated when positive and negative currents are passed through the base material and the stud, respectively, and they are brought close to each other.

The conventional inverter arc welder as described above can be largely composed of a welding gun carried by a user and a power source driving device for applying a driving power for stud welding to a welding gun. In the conventional inverter arc stud welding operation, the solenoid coil is built in the welding gun, and when the driving time and the current are set in the power source driving device, the welding gun operates with the set time and current. Here, the welding gun is about 4 Kg which can be used by the operator and can not be mounted on the welding gun. In other words, a conventional inverter arc stud welding machine welds a stud bolt to a base material by melting a stud bolt to generate an arc as a part of the stud bolt falls from a base material or a reinforcing bar to heat the base material. There is a problem in that it is difficult to operate the solenoid provided in the welding gun due to the restriction on the length and the weight in order to join the reinforcing bars and the bars or rods used in the field by stud welding.
