Safety welding tongs for electric welding machine

Abstract

The invention relates to the technical field of electric welding equipment, and discloses a safety welding tongs for an electric welding machine, which includes a handle, a handle is movably hinged on the right side of the handle, and a conductive clamping head is fixedly connected to one end of the right side of the handle , the left side of the handle is fixedly connected with an external electrical connection wire, the front of the inner cavity of the handle is fixedly installed with a first hollow electrical connection block connected with the external electrical connection wire, and the front of the inner cavity of the handle is located at the first A second hollow electrical connection block is fixedly installed on the right side of the hollow electrical connection block. The safety welding tongs for electric welding machine, through the arrangement of the first hollow electric connection block, the second hollow electric connection block, the button, the large gear ring, the small gear ring, the cooperation of the first straight rack and the second straight rack, makes the During the use of the welding tongs, it is necessary to press and hold the button to energize the welding tongs, thereby preventing the welding tongs from being energized all the time, preventing external causes from causing the human body to become an intermediate conductor, and preventing electric shock accidents.

Description

technical field [0001] The invention relates to the technical field of electric welding equipment, in particular to a safety welding tongs for electric welding machines. Background technique [0002] The electric welding machine uses the high-temperature arc generated when the positive and negative poles are short-circuited in an instant to melt the solder on the electrode and the material to be welded, so as to combine the objects to be contacted. Its structure is very simple, which is a high-power transformer. [0003] During the use of the welding tongs of the current electric welding machine, its internal circuit and welding tongs are continuously charged, but when the welding rod is not in contact with the structure to be welded, the circuit cannot be connected, so it is easy to leave a safe Hidden danger, a certain part of the hand or body is in contact with the live part of the welding rod or welding tongs, while the feet or other parts of the body are not insulated f...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a safety welding tongs for an electric welding machine, which can control the power on and off of the welding tongs, and can ensure that the welding tongs of the welding tongs will not be electrified when not welding, and can ensure that the welding rod is not charged when not welding. It will be exposed, which can ensure the advantages of fast power-off of the welding tongs during electric shock, and solve the problems mentioned in the above background technology
