Abstract

The utility model belongs to an energy saving electric arc welding clip, mainly composed of a welding tong system, a main loop system and a control system. The utility model has the advantages of simple manufacture, convenient operation, low cost, remarkable energy saving effect, etc. The goal of energy-saving operation of an electric welding machine is achieved.

Description

Energy saving electric arc welding clip

The utility model belongs to the electric welding machine energy saver.

At present, the electrode holders of use do not possess the function that makes the electric welding machine energy-saving run, and to making in the intermittent time of welding, electric welding machine still puts into operation, has wasted a large amount of electric energy in vain.

The purpose of this utility model is to have adopted new electrode holders and control system, has solved the problems referred to above, has reached in the intermittent time that electric welding machine does not weld, and makes electric welding machine out of service, thereby has realized the purpose of electric welding machine light-load energy saving.

This reality is novel to be made up of soldering turret system, primary heat transport system and control system.The soldering turret system is made up of microswitch 2SA and soldering turret, switch 2SA is arranged on the handle of soldering turret.Primary heat transport system is made up of knife switch QS, fuse 1FU and 2FU, A.C. contactor KM, electric welding machine TM.Control system is made up of fuse 3FU and 4FU, gauge tap 1SA, ac contactor coil KM, control transformer TC, under-voltage replay KA.

The energy-saving electrode holders of the utility model, manufacture simple, easy to use, cheap, power savings is remarkable, can make the electric welder no-load electric current be reduced to zero.

Be the utility model description of drawings below.

Figure (1) is the primary heat transport system figure of energy-saving electrode holders.

Figure (2) is the control system figure of energy-saving electrode holders.

Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described: energy-saving electrode holders are made up of soldering turret system, primary heat transport system, control system.The soldering turret system is made up of soldering turret and microswitch 2SA, microswitch is placed on the welding clamp handle two-end-point 7 and 4 of microswitch 2SA, 2 connections of 5 and B7 of the low-voltage relay KA wire loop by duplex wire and control system.When with portable soldering turret, switch 2SA connects, and when putting down soldering turret, switch 2SA disconnects.Primary heat transport system is the upper end that power line L1 and L2 is caused knife switch, and the knife switch lower end is connected with A.C. contactor KM upper end through fuse 1FU, 2FU, and the A.C. contactor lower end is connected with electric welding machine TM.Control system is made up of fuse 3FU and 4FU, gauge tap 1SA, ac contactor coil KM, control transformer TC, under-voltage replay KA.After the knife switch QS of primary heat transport system closed, supply voltage caused A.C. contactor main contact L3, L4 point-to-point transmission through fuse 1FU and 2FU.At this moment in control system, supply voltage is caused between 1,2 two, make the primary side B5 of control transformer TC, B6 point-to-point transmission obtain supply voltage, thereby its secondary side B7, B8 obtain a voltage U 2 through fuse 3FU and 4FU.Under-voltage replay KA is connected on control transformer TC secondary side, if at this moment with hand electrode holders are picked up, 2SA is then closed, so low-voltage relay KA is because energising and in running order, its contact KA is 1,3 two connections, makes to exchange the KM energising of contact coil and in running order.At this moment the A.C. contactor main contact is connected voltage to the primary side B1 of electric welding machine TM, B2 at 2, so obtain a voltage U 1 at electric welding machine secondary side B3, B4 point-to-point transmission, just can weld.When in the break time of welding, as long as soldering turret is put down,, make relay K A quit work because 2SA disconnects again, its contact disconnects 1,3 point-to-point transmissions, and A.C. contactor KM is owing to decompression quits work.Its contact will cut off electric welding machine primary side voltage, and electric welding machine is quit work.The purpose of gauge tap 1SA is set, and is when the control transformer TC in the control system, under-voltage replay KA and soldering turret system break down, and for not influencing welding job, gauge tap 1SA closure directly can be connected 1,3 two points, makes the electric welding machine operate as normal.

Claims

1, energy-saving electrode holders is characterized in that: it mainly is made up of soldering turret system, primary heat transport system and control system, and the soldering turret system is made of microswitch 2SA and soldering turret, switch 2SA is arranged on the handle of soldering turret.

2, energy-saving electrode holders according to claim 1, its feature also is: control system is made up of fuse 3FU and 4FU, gauge tap 1SA, ac contactor coil KM, control transformer TC, under-voltage replay KA.
