Description

Technical field:

[0001] The utility model belongs to the technical field of electric welding machines, in particular to an electric welding machine panel. Background technology:

[0002] The electric welder uses the high-temperature arc generated when the positive and negative poles are short-circuited for an instant to melt the solder on the welding rod and the material to be welded, so as to combine the contacted objects. Its structure is very simple, which is a high-power inverter power supply. The electric welder includes a housing and a movement arranged in the housing. The housing includes a front panel, a rear panel, a cover and a bottom plate. The front panel is usually provided with ventilation holes and interfaces for connection. There are many types of interfaces, and the components connected are also different. Some are used to connect welding clamps, some are used to connect grounding clamps, some are used to connect argon gas, some are used to connect gas shielded welding guns, and some are used to connect control switches. Among them, manual welding requires connecting welding clamps and grounding clamps, so two interfaces are required. When gas shielded welding, gas shielded welding guns and grounding clamps need to be connected, so two interfaces are required. Argon arc welding requires connecting welding clamps, grounding clamps, argon gas and control switches, so four interfaces are required. Some electric welders can be used for both manual welding and argon arc welding. At this time, four interfaces for argon arc welding need to be set. When manual welding is required, argon gas and control switches do not need to be connected. Some electric welders can be used for both argon arc welding and gas shielded welding, which requires five corresponding interfaces. The front panel is usually made of strong, lightweight plastic through injection molding.
