Welding is a joining method in which separate and joined metal materials to be bonded to each other are heated and melted in a state where they are joined together or overlapped. It is a technology widely used throughout the industry including the fields of machinery and civil engineering, as well as electrical and electronic fields, and is being continuously developed to meet demands such as high quality, high productivity, and safety.

Such welding is classified into CO2 welding, MIG welding, MAG welding, TIG welding, arc welding, etc., depending on the material to be welded and the amount of current used, and arc welding or gas welding depending on whether electricity is used or gas is used. Sometimes classified.

Arc welding among the various welding is a welding method of inducing arc discharge for welding, and includes carbon arc welding, metal arc welding, high frequency arc welding and the like.

CO2 welding and MIG welding of the arc welding is a welding method using a consumable electrode. That is, by continuously supplying the front end of the wire electrode continuously released from the reel into the arc formed in the base material so that the wire electrode is melted by heat, thereby forming a melted portion welded to the base material and welding while the melted part solidifies. To lose.

The wire feeding welding apparatus of this type requires electricity to form an arc, a consumable wire electrode, and a basic component is a welding apparatus, a wire feeder, a welding torch, a welding cable, and the like.

In addition, TIG welding is a method of generating an arc between the non-consumable tungsten welding rod and the base material and using arc heat. The TIG welding is a welding method in which a melting rod is melted and welded while supplying an inert gas to prevent oxidation and nitriding. Of course, a welding device is also used for TIG welding.

The welding device receives an AC power applied from the outside and converts the DC power to a DC suitable for welding. The welding device has a structure having a control panel on one side thereof.

As shown, the portable power supply device 31 according to the present embodiment includes a welding machine 33 having a control panel 41 and a common wire feeder 35 provided on one side of the welding machine 33. do.

Inside the casing 39 of the welding machine 33, a control unit including a converter, an amplifier rectifier inverter, a pump, or the like for converting electric power supplied from the outside into a direct current is disposed. The internal configuration of the casing 39 is similar to that of a general welder.

In addition, the control panel 41 is provided with various switches for driving the welding machine 33 and the common wire feeder 35, a port to which a welding cable or a gas supply tube is connected.

In addition, the power connector 51, the gas terminal 53, the connecting port 55, and the like are disposed on the opposite side of the control panel 41, that is, the common wire feeder 35.

As described with reference to FIG. 2, the power connector 51, the gas terminal 53, and the connecting port 55 may include a connection part for connecting the general welding device (19 of FIG. 2) to the portable power supply device 31. 57). When the general welding device 19 is not used, nothing is connected to the connecting portion 57.

Specifically, the power connector 51 switches the function selection switch 43, which will be described later, to use the portable power supply 31 as the sole function of the wire feeder, and thus, the power line of the single cable 23 (not shown). This is the part that is connected.

Power supplied to the power connector 51 through the single cable 23 is transmitted to the welding torch.

In addition, the gas terminal 53 is a portion to which the gas supply line of the single cable 23 is connected in order to use the welding device 31 as a wire feeder. The gas supplied to the gas terminal 53 is used for welding.

In addition, the connecting port 55 is a port to which the control line is connected.

switches

43, 45, 47, and 49 is a seesaw type switch and allows one of two options to be selected.

The function selection switch 43 is a switch for determining whether to use the welding device 31 or only the common wire feeder 35 in the welding device 31.

When the function selection switch 43 is pressed upward, for example, to select a welding machine, the portable power supply device 31 itself can be used as the original welding device. In other words, the welding machine 33 can be driven to perform welding. The welding at this time may be a CO 2 welding or a MIG welding requiring a wire electrode, or a TIG welding or a MMA (passive arc) welding without using a wire electrode.

Pressing the function selector switch 43 downward selects the wire feeder function. The wire feeder function is limited to the use of the welder 33 and can use only the common wire feeder 35. Since the welding machine 33 is not used, the power supply for driving the welding machine 33 is cut off.

In addition, before the function selection switch 43 is pressed down or even after pressing, the connection portion 57 and the general welding device 19 must be connected using the single cable 23.

Selecting the wire feeder function through the function selection switch 43 as described above, while operating the general welding device 19 in a state in which the general welding device 19 is connected using a single cable 23, the common wire feeder 35 is operated to supply the wire electrode.

The wire switch 45 is a switch operated in a state in which the function selection switch 43 is pressed upwardly, that is, in a state where a welding machine using function is selected.

When the wire switch 45 is pressed upward to select WIRE, the common wire feeder 35 is activated to supply electrode wires. In the case where CO 2 welding or MIG welding is required for the wire electrode, both the function selection switch 43 and the wire switch 45 should be pressed upward.

In addition, when performing TIG welding or MMA (passive arc) welding which does not require a wire electrode, the wire switch 45 is lowered and NO wire is selected. If NO WIRE is selected, only the welder 33 is operated and the common wire feeder 35 is not operated.

In addition, the gas supply switch 47 is a switch for determining whether to supply gas to the welding torch. When the gas supply switch 47 is raised up, the gas is supplied, and when it is down, the gas supply is cut off.

On the other hand, the inching switch 49 operates the common wire feeder 35 to advance the wire electrode to the torch side through the welding cable, and to move the wire electrode used to enter the welding cable to the rear. This switch selects reverse mode.

The reverse mode implements an operation of, for example, performing CO 2 welding using a wire electrode and then reversing the wire electrode from the welding cable when switching to TIG welding. If a wire electrode is contained in the welding cable, it may cause interference with the tungsten electrode or the MMA welding rod, thereby moving the used electrode backward.

As a result, the portable power supply device having the common wire feeder according to the present embodiment made as described above operates in various modes, that is, the welding machine 33 through the function selection switch 43 and the wire switch 45 and the like. And the combined operation of the wire feeder 35, the single operation of the welder 33, and the single operation of the wire feeder 35 can be selectively implemented, thereby enabling a wide range of use and economical operation.
