Abstract

Disclosed is a no-load energy saving device for an electric welding machine, including an electric welding plier, an alternating current contactor, a transformer and a control switch. The alternating current contactor controls the electric welding machine to work; the transformer provides working power supply for the coil of the alternating current contactor; the control switch is arranged on the electric welding plier; the control switch includes a control button and two wafers; the control button is arranged on the outer shell of the electric welding plier; the two wafers contact the wafer of the control button; one of the two output terminals of the transformer is connected to one end of the coil of the alternating current contactor by a conducting wire, and the other of the two output terminals of the transformer is connected to the other end of the coil of the alternating current contactor through the conducting wire and the control switch; the control switch controls the alternating current contactor to attract or disconnect, so as to control the electric welding machine to work. The feature of the utility model is: the no-load energy saving device can preferably solve the problem of empty load and power consumption of the electric welding machine, and the operation is extremely convenient.

Description

The electric welder no-load energy-saving appliance

Technical field:

The utility model relates to electric welding machine, specifically a kind of electric welder no-load energy-saving appliance.

Background technology:

Because generally once not welding, do not finish by a lot of workpiece; thereby electric welding machine mostly is a discontinuous operation; there is the considerable time to be in unloaded power consumption state; this will waste a large amount of electric energy; particularly present electric welding machine all is the work with electric brake control electric welding machine, when the need hesitation, then needs electric brake is left behind; when needing electric welding machine work, again electric brake is closed.So again and again, be very much trouble.Sometimes even forget the pass power supply.

Summary of the invention:

In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of electric welder no-load energy-saving appliance that can better solve electric welder no-load power consumption problem and make things convenient for the welder power switch.

The purpose of this utility model is to realize like this, it comprises electrode holders, it is characterized in that: also further comprise the A.C. contactor of control electric welding machine work and the transformer of working power is provided and is located at gauge tap on the electrode holders for this ac contactor coil, this gauge tap comprise the control button that places on the electrode holders shell and can with contacted two contacts of this button contact, one links to each other with ac contactor coil one end through lead in two outputs of transformer, and another links to each other with the ac contactor coil other end through lead, gauge tap.By the adhesive or the disconnection of gauge tap control A.C. contactor, control the work of electric welding machine thus.

Characteristics of the present utility model are better to solve electric welder no-load power consumption problem, and operation is extremely convenient.

Below in conjunction with accompanying drawing the utility model is explained.

Description of drawings:

Fig. 1 is the utility model circuit theory diagrams;

Fig. 2 is the electrode holders structural representation of band gauge tap;

Fig. 3 be among Fig. 2 A-A to local enlarged diagram.

The specific embodiment:

By accompanying drawing as can be known, the utility model is made of the electrode holders 1 of A.C. contactor CJ, transformer BY and band gauge tap.Gauge tap is by placing the control button 2 on the electrode holders shell 11 and can constituting with these button contact 8 contacted two contacts 4,5, one links to each other with A.C. contactor CJ coil one end through lead in two outputs of transformer BY, and another links to each other with the A.C. contactor CJ coil other end through lead, gauge tap.By the adhesive or the disconnection of gauge tap control A.C. contactor, control the work of electric welding machine DNJ thus.Transformer BY output voltage is 25-36V, i.e. operation-control switch under safe voltage.The duty of the indicator lamp 3 expression electric welding machines that are provided with on electrode holders shell 11 is convenient to the operator and is observed, and the operator can not forgotten close welder power.Sequence number 10 is that electrode holders copper core, sequence number 9 are lead for resistance, sequence number 6 among the figure, and sequence number 7 is the electrode holder line.
