Abstract
The utility model relates to a portable miniature electric welding machine with wind cooling, which is a miniature electric welding machine with cooling apparatus. The utility model is characterized in that a fanner is arranged in a miniature electric welding machine, hooks are arranged on the sidewalls of the outer casing of the miniature electric welding machine, and a voltage regulating tap is arranged in the transformer of the miniature electric welding machine.
Description
The utility model relates to a kind of electric welding machine, particularly a kind of miniature electric welding machine of portable air-cooled longevity that has cooling device.
Electric welding machine is a kind of important tool of people's weld metal material, and it is little, in light weight that particularly miniature electric welding machine has a volume, uses the advantage of 220 volts power supplys, brings great convenience to the work of people's weld metal material.But present employed miniature electric welding machine, exist can not long time continuous working defective, fault is many, this is because its volume is little, the radiating condition difference intrinsic defective so that make miniature electric welding machine, insulating materials heat ageing process is fast, service life is not long, and water-cooled machine structure complexity is carried inconvenience, and it is unreliable to use, when use in the area that these more external supply voltages are lower, its cisco unity malfunction.
The purpose of this utility model provides a kind of with wind pressure cooling electric welder transformer, the not overheated miniature electric welding machine of portable air-cooled longevity to guarantee continuous operation.
The utility model is finished with following mode, the miniature electric welding machine of portable air-cooled longevity is included in installing welding transformer and cover and handle on the base plate, is equiped with ventilation blower on base plate, the air port of ventilation blower is equiped with hook towards welding transformer on the lateral wall of cover.There are two or more tap changers the high and low pressure both sides of welding transformer, and hook has one or two.
The miniature electric welding machine of the portable air-cooled longevity of the utility model, because the installing ventilation blower carries out air blast cooling to welding transformer in electric welding machine, improved welding transformer coil long-time continuous heating power, and the temperature rising phenomenon that causes, thereby delayed the heat ageing process of insulating materials, the service life of improving miniature electric welding machine.Because the utility model is provided with tap changer in the high-low pressure both sides of welding transformer, make under the situation that supply voltage reduces significantly, but operate as normal still is often on the low side to be suitable for supply voltage such as mountain area, rural area, causes under the situation of common welding machine cisco unity malfunction to use.The utility model is installed hook on the lateral wall of welding machine cover, is convenient to move carry, and some special occasions, hang welding machine up operation, can further embody the advantage of miniature electric welding machine.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Below in conjunction with accompanying drawing the utility model is described in further detail:
In Fig. 1 Fig. 2, portable air-cooled miniature electric welding machine is made up of base plate (4), welding transformer (3), cover (1), ventilation blower (2), handle (7), hook (6).Left end installing welding transformer (3) at base plate (4), the low pressure leading-out terminal of welding transformer (3) outwardly, be convenient to wiring, there are two tap changers the high-pressure side of welding transformer (3), is convenient to the situation according to supply voltage, adjusts input voltage, make welding machine energy operate as normal, low-pressure side at welding transformer (3) has two tap changers, can adjust the size of output current according to the size of current of welding rod thickness requirement.Right-hand member installing ventilation blower (2) at base plate (4).Present embodiment ventilation blower (2) adopts air blast, and its air port is between two line bags of welding transformer (3).The power supply of ventilation blower (2) is connected in the high-pressure side (220V end) of welding transformer (3).Install firmly for making air blast (2), having on the base plate (4) on the oblique support that is contained in welding transformer (3) of a bridge plate (8), bridge plate (8) holds up air blast (2), when electric welding machine is connected power work, open air blast, the heating of welding transformer (3) center line bag and iron core is blown away, play the effect of cooling.Two hooks (6) are housed on the lateral wall of electric welding hood, be convenient to electric welding machine hung on bicycle or other vehicles and carry, simultaneously, at some special occasions, during as work high above the ground, when putting, welding machine inconvenience welding machine can be hung on the scaffold, when being convenient to operation, deposit welding machine, can embody the portable advantage of microminiature welder more.
Claims (3)
1, the miniature electric welding machine of a kind of portable air-cooled longevity, it is included on the base plate (4), installing welding transformer (3) and cover (1) and handle (7), it is characterized in that on base plate (4), being equiped with ventilation blower (2), the air port (5) of ventilation blower (2) is equiped with hook (6) towards welding transformer (3) on the lateral wall of cover (1).
2,, it is characterized in that there are two or more tap changers the high and low pressure both sides of welding transformer (3) according to the described electric welding machine of claim 1.
