Embodiment Construction

[0045] The following is attached Figure 1-6 The application is described in further detail.

[0046] The embodiment of the present application discloses a battery welding machine, referring to figure 1 , figure 2 , including a housing 1, a welding machine circuit 8 installed in the housing 1, a welding torch 18 is connected to the output end of the welding machine circuit 8, a power line 19 is connected to the input end of the welding machine circuit 8, and the welding machine circuit 8 passes through The power line 19 is connected to an external power source 20 . The external power supply 20 may be a vehicle storage battery, or a self-contained storage battery. Both the external power supply 20 and the battery welder body are easy to carry, and are especially suitable for use in outdoor operations.

[0047] see image 3 , Figure 4 Two guide strips extending along the height direction of the housing 1 are fixed on both end surfaces of the housing 1 , and a slide groov...

Abstract

This application relates to a battery welding machine, which includes a housing and a welding machine circuit installed in the housing. An exhaust fan is installed on one side wall of the housing. The air inlet of the exhaust fan communicates with the inner cavity of the housing. The outside world is connected, and the first cover covering the air outlet of the exhaust fan is installed on the outer wall of the shell. A dust filter that blocks outside dust from entering the air vent. When the battery welder is not in use, the first cover is set on the exhaust fan, and the external dust cannot enter the shell through the exhaust fan. When the battery welder is in use, the first cover is opened, so that the exhaust fan can go out normally. Exhaust air; in addition, the dust filter itself has a dust-blocking effect, so no matter whether the battery welder is working or not, the dust is not easy to enter the casing through the dust filter, so that the battery welder is not easily disturbed by dust when it is used outdoors.

Description

technical field [0001] The present application relates to the field of electric welding machines, in particular to a battery welding machine. Background technique [0002] General welding machines need 220v or 380v AC as the power supply. However, when the electric welding machine needs to be used outdoors, it is difficult to find a suitable AC power supply for a while, which makes it inconvenient to use. [0003] At present, the Chinese patent with the notification number CN106425029B has started a battery-type welding machine, including a power cord, a housing, a welding machine circuit and a welding torch. The welding machine circuit is located in the housing, and the input end of the welding machine circuit is connected to the power line. The output end of the circuit is connected to the welding torch, and the power line is used to switch on the DC power supply. The welding machine circuit includes a push-pull circuit, a first push-pull drive circuit, a second push-pull...
