Abstract
The utility model discloses an energy-saving electric welder, whose structure is substantially the same with the ordinary welders. The utility model is characterized in that an AC contactor (2) is arranged in the primary coil of the welder (1), the AC contactor is controlled by the electric welding pliers handle (4) with a microswitch (5). A sheath is arranged on the external of the electric welding pliers (4). A strip of insulating flexible cord (8) is arranged in the internal of an electric welding flexible cord (6), the electric welding flexible cord (6) connects with the microswitch (5), the AC contactor (2) is provided with a delay relay (3) for solving the phenomenon of arc-breaking during welding. The energy saving electric welder can switch off automatically when the welder is of zero load. The utility model has the advantages of energy saving, long service life, and safety assurance. The accidents of electric shock can be stopped because that the electric circuit is off when a welding rod is being changed by the operator.
Description
The present invention belongs to the industrial electric apparatus product.
Before the present invention, all types electric welding machine that each factories and mines is used, as long as connect power supply, no matter just in welding job whether whether, the primary coil of electric welding machine is charged all the time, in this case, when not welding, will waste a large amount of electric energy virtually.Moreover, because the operator is when changing welding rod, electric welding machine is charged all the time, and electric shock accidents happens occasionally.
The present invention is directed to above-mentioned shortcoming and done improvement, the present invention proposes and in the primary coil of electric welding machine, install an A.C. contactor additional, control the primary coil power supply of electric welding machine with manual method.The specific embodiment of energy-saving electric welding machine of the present invention and electrical principle thereof are referring to Fig. 1.Among Fig. 1, a device A.C. contactor (2) on the primary coil of electric welding machine (1), (2 ') are the contact points of A.C. contactor (2); Be used for controlling the time-delay relay (3) of A.C. contactor (2).(3 ') are the normal battles of time-delay relay (3).Microswitch (5) is housed in electric welding pliers handgrip (4), and there is sheath (7) electric welding pliers handgrip (4) outside.The inner special flexible cord (8) with a φ 1.5mm tape insulation of flexible wire for electric welding (6) connects microswitch (5) and uses.
The energy-saving welding machine course of work of the present invention is as follows:
The operator takes off electric welding pliers handgrip from the hook (9) that special key is housed, and the primary coil of the transformer that capacity is very little (10) is connected power supply.When the operator held electric welding pliers handgrip (4), owing in the electric welding pliers handgrip (4) microswitch (5) is housed, at this moment microswitch (5) had been connected time-delay relay (3).Time-delay relay (3) conducting, A.C. contactor (2) is connected simultaneously.Electric welding machine is switched at this moment, can welding job.During to be welded stopping, the operator leaves electric welding pliers handgrip (4), and time-delay relay (3) has been cut off in microswitch (5) automatic disconnection, and A.C. contactor after 4～5 seconds (2) disconnects, and electric welding machine is stopped power supply.Therefore saved the electric energy when not welding.
Because electric welding machine is not charged when not welding job, the operator has accomplished safety in production when changing welding rod.In case the user hangs back hook (9) to electric welding pliers handgrip (4), electric welding machine all cuts off the power supply.
Electric welding machine energy saver of the present invention, simple in structure, do not need specific (special) requirements just can use.At a BX
1The electric welding airborne device energy saver of the present invention of-600A can economize on electricity about 2500 degree every year.If nearly ten thousand electric welding machines that big industrial city is had all are furnished with energy saver of the present invention, then annual saves energy reaches several ten million degree.
Claims (2)
1, a kind of energy-saving electric welding machine, it is characterized in that on the primary coil of electric welding machine [1], being provided with an A.C. contactor [2], time-delay relay [3], device microswitch [5] in electric welding pliers handgrip [4], in flexible wire for electric welding [6],, connect microswitch [5] and use with the special flexible cord [8] that insulate that has of a φ 1.5mm.
2,, it is characterized in that there is sheath (7) outside of electric welding pliers handgrip (4) according to the described electric welding pliers of claim 1 handgrip (4).
