Abstract
The present invention discloses a schematic circuit diagram of a zero load shutdown device of an electric welding machine. The scheme of the present invention comprises: a contactor is serially connected between an electric welding machine and a power supply; a voltage reduction device and a control switch are placed between the power supply and a contactor coil so as to form a controllable power supply circuit. According to the working requirements, the contactor can be powered or interrupted to make the contactor close or release. Accordingly, the electric welding machine can be powered or interrupted to achieve the purpose that the electric welding machine can be instantly interrupted when having zero load.
Description
The present invention relates to a kind of circuit of electric welder no-load halting device.
As described in the circuit theory of electric welder no-load halting device saves for the 1162nd page the 76 as volume in " practical electrotechnics question and answer " at present: when electric welder no-load, can not cut off the power supply immediately; therefore still have energy consumption during electric welder no-load, and as " bonding " takes place to cause major accident.
The objective of the invention is: when electric welder no-load, outage immediately, the energy consumption when reducing electric welder no-load is avoided causing " bonding " incident and is taken place.
Technical scheme of the present invention is: contactor of series connection between power supply and electric welder transformer.Decompression device input termination power, an end of output one termination contactor coil, the other end is connected the other end of contactor coil by gauge tap, forms and gives contactor coil supply line.Connect power supply when using electric welding machine, open gauge tap, power supply is powered to contactor coil, the contactor adhesive, and power supply is given the electric welding machine powered operation, and when stopping welding, closing control switch, power supply stop to the contactor coil power supply, and contactor discharges, the electric welding machine outage.For easy to use, gauge tap is installed on the lever of electrode holders, thoroughly does away with the edge lead with two and is connected to output one end of decompression device and an end of contactor coil respectively.Also can remain a lead, replace with electric welding machine electrode holder line, the end that the electrode holder line is connected with the electric welder transformer output is connected an end of contactor coil with lead.
Contactor can be a direct current, only need install rectifier additional in contactor coil supply line.
Above-mentioned circuit of electric welder no-load halting device can supply outage to electric welding machine at any time according to need of work; power consumption when having solved electric welder no-load substantially; and the voltage of control circuit is safe voltage, and this device is safe and reliable, thereby has increased the security performance of electric welding machine.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the circuit theory diagrams of electric welder no-load halting device
Circuit theory diagrams shown in Figure 1 are most preferred embodiment of the present invention, and A.C. contactor 2 is connected on 1 of power supply and electric welder transformer.The input termination welder power of miniature transformer 3, one end of output one termination contactor coil 6, the other end is connected and installed an end of the gauge tap 4 on the electrode holders 5 by insulated conductor, another termination electrode holder line of gauge tap, the electrode holder line is connected the other end of contactor coil 6 with insulated conductor.When using electric welding machine, connect power supply, open the gauge tap 4 on electrode holders 5 levers, power supply is supplied with contactor coil 6 safe voltages by miniature transformer 2, and contactor 2 gets electric adhesive, and power supply is powered to electric welding machine.When stopping welding, closing control switch 4, power supply stop to contactor coil 6 power supplies, and contactor 2 discharges, and welder power disconnects.
