Abstract
The utility model relates to a high-efficient energy-saving automatic switch of an electric welder. A contactor C is connected between a power supply and the electric welder. The power supply is connected with a transformer which outputs low voltage. A control return circuit which is composed of a push-button switch QA and a coil of the contactor C is between the output terminals of the transformer. The turn-on or the shut of the contactor C is controlled by the control return circuit. The push-button switch QA is installed on a welding handle. The on-off of an input return circuit of the electric welder enables a using point to be movably controlled. The utility model has the advantages of safe use, convenience and obvious energy-saving effect.
Description
The utility model relates to a kind of electric welding machine switch.
The electric welding machine that uses all is a break-make of controlling its input circuit with the method for cutting off the electricity supply at present, generally all be to connect power supply when being on duty, the work for the treatment of finishes or comes off duty and cut off the electricity supply afterwards, so, electric welder no-load time input winding is leading to always outside weld interval, consuming electric energy, wasting energy.
The purpose of this utility model will provide a kind of electric welding machine automatic switch exactly, can cut off the electricity supply easily outside weld interval at electric welding machine, saves electric energy.
Energy-efficient electric welding machine automatic switch provided by the utility model, between power supply and electric welding machine, be connected to contactor C, be connected to transformer on the power supply, output LOW voltage, between the transformer output, coil by press button QA and contactor C is formed control loop, and control contactor C is switched on or switched off, and described press button QA is installed on the electric weld handle.
The energy-efficient electric welding machine automatic switch that adopts technique scheme to make uses crawl control, and press button is installed on the electric weld handle, during welding, hold electric weld handle, press the button, welder power is just connected, welding finishes, unclamp electrode holder, release button correspondingly, power supply just disconnects, easy to use, energy-saving effect is obvious.The contactor control circuit is a low-voltage, can not cause electric shock accidents, and is safe in utilization.
Accompanying drawing is a schematic diagram of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described.Be connected to A.C. contactor C between power supply and electric welding machine, form main circuit, the output of electric welding machine connects electric weld handle, on power supply, also be connected to transformer, export 20 volts low-voltage, between its output, be connected to the coil of press button QA and A.C. contactor C, form control loop, above-mentioned press button QA is installed on the electric weld handle, during welding, hold electric weld handle, thumb presses the button switch, power connection, welding finishes, unclamp electrode holder, power supply disconnects, and forms crawl control.Because press button is installed on the electrode holder, for reducing number of conductors, can be communicated with the output of transformer, like this with direct-connected output of press button QA and electric welding machine, outlet line with electric welding machine replaces transformer to output to the circuit of QA, and the circuit that leads on the electric weld handle just has only two.
