BRIEF DESCRIPTION OF THE DRAWINGS The objects, particular advantages and novel features of the present invention will become more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements are assigned the same number as much as possible even if they are displayed on different drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a general arc welding system, Figure 2 is a perspective view of a general wire feeder.

As shown in FIGS. 1 and 2, the general arc welding system 1 includes a welder body 10, a gas cylinder 20, a torch 30, and a wire feeder 40.

The welder main body 10 is connected to a power supply and supplies electric power to the wire feeder 40. The welder main body 10 and the wire feeder 40 may be connected to the power cable 11 and the control cable 12, and the electric power supplied to the wire feeder 40 through the power cable 11 may be welded. It flows into the wire 42 supplied to it.

The gas bomber 20 (Gas bombe) supplies an inert gas such as carbon dioxide gas to the wire feeder 40 through the gas hose 21. At this time, the wire feeder 40 delivers the gas to the torch 30 to be sprayed to the welding site.

The torch 30 injects gas to the welded portion so that welding is performed. The torch 30 may be manufactured in the form of a gun so that an operator can grip it, and may inject the gas supplied from the wire feeder 40 to the welding site.

In this case, the torch 30 may control whether the wire 42 is supplied by applying an on / off signal to the wire feeder 40 through a switch (not shown). The welder main body 10 is provided with a switch (not shown), but the switch is further provided with the torch 30 by an operator performing welding at a place far from the welder main body 10. This is because the on / off switch provided in the module cannot be operated.

The wire feeder 40 unwinds the wire 42 wound on the spool 41 with the drive motor 43 and continuously supplies it to the welding site. In addition, the wire feeder 40 includes a frame 44, a plurality of rollers 45 for supplying the wire 42, and a control unit 46 for adjusting the current or supply speed flowing through the wire 42. do.

The wire feeder 40 is configured in a portable size and weight for the convenience of welding operation. Therefore, since the welding worker grasps the frame 44 of the wire feeder 40, lifts it, and arranges it near the welding site, the wire feeder 40 is at least separated from the welder main body 10 and the gas cylinder 20. It is connected to the power cable 11, the control cable 12, the gas hose 21 with a few meters to several tens of meters apart.

At this time, the welding current supplied through the power cable 11 flows to the wire 42 fed from the wire feeder 40, and the inert gas supplied to the gas hose 21 passes through the wire 42 at the torch 30. By spraying around, welding is performed.

However, since the wire feeder 40 cannot operate in the absence of the welder main body 10, when the wire feeder 40 stops working for an unknown reason, the operator needs to know whether there is a failure. There is no choice but to manipulate the welder body 10 directly. That is, since the wire feeder 40 placed at the welding site cannot be inspected at the position where the wire feeder 40 is placed, the inspection can be performed only by moving to the vicinity of the welder main body 10, resulting in a waste of labor.
