Abstract

The utility model discloses an electricity saver for avoiding the no-load power consuming of an AC welder, comprising a miniature transformer, a master switch on the handle of an electrode holder and an AC contactor. When weld is carried out, the electrode holder is held by hands, a button on the electrode holder is pressed, and weld can be carried out immediately; when weld is stopped, the button is unclamped, and the primary source of a welder is cut off to avoid the phenomenon of the no-load power consuming of the primary winding of the welder in order to achieve the purpose of power saving.

Description

The A.C. welder battery saving arrangement

The present invention relates to a kind ofly can make A.C. welder battery saving arrangement of consumed power not when zero load.

The elementary winding input of existing A.C. welder directly is connected on the knife switch lower end, A.C. welder input power connection and disconnection.Controlled by knife switch.In welding process, if butt joint workpiece or change welding rod must stop weldering, stop weldering time varying length, especially in the high-altitude welding or from electric welding machine place welding far away, if power off time is longer, the also inconvenience outage of going to operate a switch of electric welder.The elementary winding of electric welding machine is not if cut off the power supply during this period, and elementary winding just has the phenomenon of unloaded power consumption, the waste that the electric welder no-load power consumption causes.Be far from suitable with current energy-intensive situation.

Task of the present invention is that a kind of battery saving arrangement that can make A.C. welder not consuming electric power when zero load will be provided.

Below with reference to accompanying drawing invention is described in further detail.

Miniature transformer (1) input voltage is two kinds: 380 volts and 220 volts, can choose any one kind of them during use, but will and A.C. welder (3) input voltage be consistent, no matter miniature transformer (1) input voltage is with 380 volts or with 220 volts, its output voltage should be between 36 volts to 40 volts, to guarantee personal safety.Control switch (4) is housed in the electrode holders handle, exposes a button on the handle.A.C. contactor (2) sucking coil input voltage is 36 volts.Miniature transformer (1) secondary windings, control switch (4), A.C. contactor (2) sucking coil winding three forms the closed-loop path, sucking coil input power connection and disconnection, be subjected to control switch (4) control, A.C. contactor (2) is connected between elementary winding of electric welding machine (3) and the knife switch, during welding, the electric welder hands electric earthenware (5), control switch (4) button on the electrode holders handle press...withes one's finger down, control switch (4) is connected, A.C. contactor (2) sucking coil power supply is switched on, and the elementary winding power supply of electric welding machine (3) is connected in A.C. contactor (2) adhesive immediately, electric welding machine (3) puts into operation, just can weld.If change welding rod, or the butt joint workpiece, in the time of need stopping welding, the welder needs only one and looses one's grip, control switch (4) is subjected to the spring leaf effect, automatic disconnection, contactor (2) sucking coil power supply is cut off, and contactor (2) separates, the elementary winding power supply of electric welding machine (3) is cut off, electric welding machine (3) is out of service, has avoided the phenomenon of the unloaded power consumption of electric welding machine (3), thereby has reached aim of power saving.If in the time of need welding again, just in a flash before, press control switch (4) button, can continue welding at welding rod contact workpiece (6).

The present invention is simple in structure, and cost is low, new and old various A.C. welder all is suitable for, and does not change the electric welding machine internal structure.

Accompanying drawing is a basic circuit diagram of the present invention.
