The electric welding machine comprises a base, a machine shell fixedly connected to the base, an operation panel arranged on the machine shell, a printed circuit board (PCB) fixedly arranged on the operation panel, and a gasoline engine and a generator which are fixedly connected to the base, wherein a control circuit is arranged on the PCB; a welding gun connected with the control circuit is arranged on the operation panel; the gasoline engine is connected with the generator; the generator is connected with the PCB and can transmit alternating current to the control circuit; and the control circuit can convert the alternating current into low voltage direct current and outputs the low voltage direct current through the welding gun. The utility model has the advantages that: the electric welding machine has small volume and light weight, is convenient to carry and is not limited by the position of the external power supply.
Description
Technical field
The utility model belongs to the electric welding machine technical field, relates to a kind of electric welding machine.
Background technology
Existing electric welding machine generally is to be connected with extraneous power supply through plug; Through extraneous power supply it is supplied power; The direct current that extraneous high-tension electricity is converted to low pressure is exported, and the problem of its existence is: owing to be to come electric welding machine is supplied power through extraneous power supply, will receive the restriction of extraneous power supply when electric welding machine is worked like this; When remote can not extraneous power supply be provided the time at some; Electric welding machine just can not get normal work, and this connects electric wire and also trips etc. through regular meeting and influence staff's efficient operation.Existing electric welding machine volume ratio is bigger simultaneously, and weight is big, needs at least two people to carry, if working environment has only a staff just can not carry, has influenced operating efficiency like this.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, and it is little, in light weight and do not receive the electric welding machine of extraneous power limitations to have proposed a kind of volume.
The purpose of the utility model can realize through following technical proposal: a kind of electric welding machine; Comprise base and be connected in the casing on the base; It is characterized in that: this electric welding machine also comprises the guidance panel that is installed on the casing, is fixedly mounted on the pcb board on the guidance panel and is connected in gasoline engine, the generator on the base; Pcb board is provided with control circuit, and guidance panel is provided with the welding gun that is connected with control circuit, and described gasoline engine is connected with generator; Described generator is connected with pcb board and can carries alternating current to give control circuit, and described control circuit can convert above-mentioned alternating current to low-voltage DC then through above-mentioned welding gun output.
In above-mentioned a kind of electric welding machine, described generator is a magneto.
In above-mentioned a kind of electric welding machine; Described arc welding gun head is provided with the Hall element that is connected with above-mentioned control circuit; The oil inlet pipe of described gasoline engine is provided with the magnetic valve that is connected with above-mentioned control circuit; Described Hall element can detect the current information of arc welding gun head output current size and current information is fed back to control circuit, and control circuit can be controlled the aperture of above-mentioned magnetic valve according to the current information that receives.
Compared with prior art, this electric welding machine provides power by gasoline engine, and gasoline engine drives generator for electricity generation; Supply power then to welding gun welding usefulness; Replaced by extraneous power supply power supply, so just no longer received the position limit of extraneous power supply, no matter where can carry out operate as normal.Simultaneously, gasoline engine, generator and other each component layouts are reasonable, and volume is little and in light weight, and a people can carry, operate very convenient, high efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, base; 2, casing; 3, guidance panel; 4, gasoline engine; 5, magneto.
The specific embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technical scheme of the utility model is done further to describe, but the utility model is not limited to these embodiment.
As shown in Figure 1; This electric welding machine comprises base 1 and is connected in the casing 2 on the base 1; This electric welding machine also comprises guidance panel 3, is fixedly mounted on the pcb board on the guidance panel 3 and is connected in gasoline engine 4, the generator on the base 1; Casing 2 is connected on the side of base 1, and gasoline engine 4 is connected on the opposite side of base 1 with generator side by side, and guidance panel 3 is fixedly mounted on the casing 2.Pcb board is provided with control circuit; Guidance panel 3 is provided with the welding gun that is connected with control circuit; Gasoline engine 4 is connected with generator, and generator is connected with pcb board and can carries alternating current to give control circuit, and control circuit can convert above-mentioned alternating current to low-voltage DC then through welding gun output.Generator in the present embodiment is a magneto 5, and magneto 5 relative volumes are less.Arc welding gun head is provided with the Hall element that is connected with control circuit; The oil inlet pipe of gasoline engine 4 is provided with the magnetic valve that is connected with control circuit; Hall element can detect the current information of arc welding gun head output current size and current information is fed back to control circuit, and control circuit can be according to the aperture of the current information control magnetic valve that receives.
Gasoline engine 4 drives magnetoes 5 generatings, and magneto 5 generating backs carry alternating currents to give control circuit, and rectification circuit is arranged on the control circuit, control circuit with the AC rectification step-down after arc welding gun head output through welding gun be used for welding.Hall element is monitored the output current size in real time; And size of current fed back to control circuit, when output current was below or above settings, the aperture that control circuit is correspondingly controlled magnetic valve became big or diminishes; So that the generation current of generator correspondingly becomes big or diminishes; Reach the electric current output of setting value, guarantee welding current output stably, guarantee welding quality.Simultaneously, the volume of gasoline engine 4, magneto 5 etc. is little, in light weight, and topology layout is reasonable, makes overall volume little, and is in light weight, is convenient for carrying and carries, and a people just can carry, and increases work efficiency greatly, and does not receive the restriction of extraneous power supply fully.And this electric welding machine is particularly suitable for the cheap country of steam oil ratio (SOR) electricity, replaces electricity to save use cost with gasoline.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
