Description

technical field [0001] The invention relates to the technical field of bridge steel structure construction attachments, in particular to an electric welding device for bridge construction. Background technique [0002] As we all know, the electric welding device for bridge construction uses the high-temperature arc generated when the positive and negative poles are short-circuited instantly to melt the solder on the electrode and the material to be welded, so that they can be combined with each other. In the process of structure construction, welding between steel bars is carried out to facilitate better construction of bridge steel structures and bridge attachments. It has been widely used in the field of bridge construction; existing bridge construction electric welding devices include Chassis, electric welding pliers, ground wire pliers and welding wire, the power input line, power switch, current knob, ground wire joint and electric welding pliers joint are arranged on t...

[0002] As we all know, the electric welding device for bridge construction uses the high-temperature arc generated when the positive and negative poles are short-circuited instantly to melt the solder on the electrode and the material to be welded, so that they can be combined with each other. In the process of structure construction, welding between steel bars is carried out to facilitate better construction of bridge steel structures and bridge attachments. It has been widely used in the field of bridge construction; existing bridge construction electric welding devices include Chassis, electric welding pliers, ground wire pliers and welding wire, the power input line, power switch, current knob, ground wire joint and electric welding pliers joint are arranged on the said chassis, the input end of the power input line is connected with the power supply, the output of the power input line is The power switch and current knob are installed on the left outer wall of the chassis, the input end of the ground wire clamp is connected with the ground wire joint, the input end of the welding clamp is connected with the joint of the welding clamp, and the welding wire is clamped on the welding clamp; now When using some electric welding devices for bridge construction, first clamp the ground wire clamp to the required welding work area, then clamp the welding wire on the electric welding clamp, turn on the power switch, electrify the chassis, adjust the required current through the current knob, and then Align the welding wire to the welding area and perform electric welding; it is found in the use of the existing electric welding device for bridge construction that when it is necessary to work at a high place, the worker needs to carry a lot of welding wire. After each welding wire is used up, another one is clamped. The operation efficiency is low, and both hands are required in the process of changing the welding wire, which has potential safety hazards; and a lot of smoke is generated during electric welding operations, which is harmful to the human body and has high application limitations
