Abstract
The utility model belongs to a welding holder type controller used for controlling the on-off of a welder, mainly comprising a transformer, a contactor, a relay and a switch indicator circuit. When the utility model is switched in power lines of the welder, welding workers can automatically control the on-off of the welder through a low voltage switch arranged on the welding holder according to operating situation. The utility model has the advantages of safety assurance and energy saving.
Description
The utility model belongs to the welding guard technology, the control device that particularly a kind of electric welding machine opens and closes.
There is following shortcoming in the existing electric welding machine welding operation: the one, the keying control of welding machine separates with welder's operation, after the welding machine energising, because of not closing welding machine at any time, not welding under the unloaded situation of living, still will consume certain electric energy; The 2nd, owing in the electric welding operating process, both made and do not welded work temporarily, can not arbitrarily leave about because of electrode holder is charged, particularly operation in large-area plate and canister, to make troubles to the welder, both dangerous, also be easy to generate spark phenomenon and influence the weldment quality.
The purpose of this utility model provides a kind of electrode holder formula controller that utilizes low tension switch on the electrode holder directly to be controlled the keying of electric welding machine at any time by the welder, to reach saves energy and to guarantee the safe and reliable purpose of welding operation.
The purpose of this utility model realizes with following technical proposals.
Controller of being made up of transformer, relay that links to each other with the welding machine electric power line links to each other with low tension switch on the electrode holder again.The welder opens and closes electric welding machine with the switch on the electrode holder by controller like this.
Fig. 1, controller line figure
Now in conjunction with the accompanying drawings the utility model is described in detail.
The utility model contacts CJ mainly by transformer BK, auxiliary reclay JZ and indicator lamp D1, D2, and K switch is formed.
As shown in Figure 1, on the power line of the elementary access electric welding machine M of transformer BK (A, B point), the normally opened contact JZ3 that connects contactor CJ and auxiliary reclay simultaneously forms the loop, and A, the B point that the normally opened contact C1 of contactor CJ, C2 are connected to power line below.On behalf of the red colored lamp D1 that stops to indicate, secondary three loops (1) that connect to form respectively of transformer BK connect the normally-closed contact JZ1 of auxiliary reclay JZ; (2) the normally opened contact JZ2 of the green light D2 connection JZ of indication is opened in representative; (3) relay J Z connects the K switch on the electrode holder N.
After the use of controller was power turn-on knife switch HK, the red light D1 of controller was bright, and this moment, then auxiliary reclay JZ moved as if the K switch of pressing on the electrode holder N, the JZ2 closure, and green light D2 is bright; JZ1 disconnects, and red light D1 goes out; The JZ3 closure, the contactor CJ action of switching on, then contact C1, C2 adhesive, electric welding machine is connected power supply, can implement weld job.Can grasp the keying of welding machine at any time by welder oneself according to the operation situation like this.Do not weld when alive, welding machine is shut down, and electrode holder can arbitrarily be put, and is both safe and reliable, again saves energy.
Claims (3)
1, a kind of electric welding machine electrode holder formula controller is characterized in that the power line of the elementary access welding machine (M) of transformer (BK), and connects normally opened contact (JZ3) the composition loop of contactor (CJ) and auxiliary reclay; Switch (K) composition loop on its secondary and auxiliary reclay (JZ) and the electrode holder (N).
2, controller according to claim 1 is characterized in that the normally opened contact (C1, C2) of described contactor (CJ) inserts on the power line.
3, according to the described controller of claim 1, what it is characterized in that transformer (BK) secondaryly has an indication loop of being made up of the contact (JZ1, JZ2) of lamp (D1, D2) and auxiliary reclay (JZ).
