Abstract

PROBLEM TO BE SOLVED: To unnecessitate a housing box for jig, etc., needed to welding work and to improve the working efficiency by arranging a housing part at the upper part of a box body and covering the housing part with an upper cover. SOLUTION: The box body 1 is formed as almost squared frame state and on the front surface, recessed parts 2, 3 are arranged. In the recessed parts 2, 3, an ammeter, operating buttons and terminals connected with cables are disposed. The upper cover 4 is disposed at the upper part of the box body 1 and freely opened/closed to the box body 1 with a hinge and fixed to the box body 1 with wing bolts. A partition plate 7 is fixed to the box body 1 at this periphery and the housing part 8 is formed with the box body 1. The supporting part 9a of a supporting pipe 9 protects the connecting parts of various kinds of cable parts and a frame part 9b supports the bottom surface plate. A back surface pipe is bent as U shape and further bent as near flat V shape and a frame part 10a is fixed to the side surface of the box body 1. A supporting part 10b is used as the handle at the time of carrying and also, as a stopper to the upper cover 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply for arc welding.

[0002]

2. Description of the Related Art A power supply for arc welding includes a high-voltage power supply unit such as a transformer and a control unit inside. For this reason, the power supply unit is covered with a housing to prevent an electric shock of an operator and to prevent dust on the control device unit. The housing of the power source for arc welding is formed in a substantially rectangular parallelepiped, and is generally arranged side by side on a horizontal floor. However, depending on the work site, for example, a two-stage shelf is provided, and the power source for arc welding is installed in an overlapping manner. Sometimes.

Since the output of the power source for arc welding is a low voltage and a large current, if the length of the cable on the output side is increased, energy loss increases, the welding voltage decreases, and the setting of welding conditions becomes complicated. Also, if the cross-sectional area of the cable on the output side is increased, the cable becomes heavier and the portability decreases. Therefore, when the power source and the welding site are far apart, it is often the case that the high-voltage input-side cable is lengthened and the output-side cable is kept short. Such a welding machine which is often transported has larger wheels to improve portability.

[0004]

In the welding work, protective articles such as safety glasses are required for safety. However, as a general tool, it is sufficient to use pliers in the case of a consumable electrode type arc welding work. It is not required for non-consumable electrode type arc welding operations. However, for example, when the workpiece is a pipe, a dedicated fixing jig is required for each pipe diameter, and the amount is not an amount that can be carried and carried by an operator. In the case of a dedicated fixing jig, work cannot be performed if component parts are missing. Therefore, a special storage box is provided to arrange the jigs. However, the user forgets to transport the storage box or takes a long time to fix the storage box, so that the workability cannot be improved.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a power supply for arc welding that does not require a storage box for jigs and the like necessary for welding work and can improve work efficiency.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a power supply for arc welding in which a power supply unit is covered with a housing to protect the inside of the power supply unit. It is solved by covering with a cover.

[0007]

FIG. 1 is a front view of an arc welding power source according to the present invention, FIG. 2 is a partial side sectional view, and FIG. 3 is a rear view. Reference numeral 1 denotes a housing, which is formed in a substantially square frame shape, and has concave portions 2 and 3 on the front surface. In the recess 2, an ammeter and various operation buttons are arranged. Terminals to which various cables (not shown) are connected are arranged in the concave portions 3. Reference numeral 4 denotes an upper cover, which is disposed above the housing 1. The upper cover 4 can be opened and closed with respect to the housing 1 by a hinge 5. Reference numeral 6 denotes a wing bolt for fixing the upper cover 4 to the housing 1. Reference numeral 7 denotes a partition plate, the periphery of which is fixed to the housing 1, forms a storage section 8 with the housing 1, and is isolated from a lower control section and a power supply section (not shown). Reference numeral 9 denotes a support pipe, which is bent in a U-shape and further bent into an L-shape. The support portion 9a protects a connection portion of various cables and allows a hand to be put on during transport. I have. The frame 9b supports a bottom plate (not shown). Reference numeral 10 denotes a back pipe, which is bent in a U-shape and further bent in a C-shape, and a frame portion 10 a is fixed to a side surface of the housing 1. Support part 10b
Is a hand to be put on during transport and also serves as a stopper for the upper cover 4 as shown by a two-dot chain line in FIG. Reference numeral 11 denotes a front wheel, and 12 denotes a rear wheel, each of which is supported by a bottom plate (not shown). 13 is a connection terminal of the input side cable, 14 is a gas terminal, and 15 is a fan cover.

With the above construction, the wing bolt 6 is loosened, the upper cover 4 is opened, and a fixing jig used for pipe welding is stored in the storage section 8, and then the upper cover 4 is fixed to the housing 1. Keep it. When the vehicle arrives at the welding site, the wing bolt 6 is loosened and the upper cover 4 is opened to take out necessary parts.
When the power supply for arc welding is transported to the welding site, if the input side cable (not shown) is wound around the support portion 10b, the transport of the cable becomes easy.

Incidentally, a braking device may be provided on the wheels 11 and 12. Ordinary bolts may be used for the wing bolts 6.

[0010]

As described above, according to the present invention,
The power supply unit is covered with a housing, and a storage unit is provided at the top of the housing and covered with an upper cover, so there is no need to provide a storage box for jigs and tools, so transportation is easy and work efficiency is improved. I can do it.
