Abstract
The utility model relates to an AC arc welder with double welding handles, which comprises a power supply device and welding handle units, wherein the two electrical energy output ends 0 and 0' of the power supply device are respectively connected with two welding handles 1 and 1' via respective connecting cable. The two electrical energy output circuits of the power supply device are respectively connected in series with a lifting coil Wi and a lifting coil Wi' which are respectively in magnetic coupling with a secondary coil W2 of a main transformer B1. An arc welder can weld two points at a distance in sequence or simultaneously without influencing each other. The arc welder with double welding handles also has the automatic on-off control function of the power supply. Only when the welding handles are held in hands, the power supply starts to supply the power, so the work efficiency is raised obviously. The utility model has the advantages of energy saving, and safe and convenient operation.
Description
The utility model relates to ac arc wedling machine, is specifically related to have the ac arc wedling machine of two electrode holders.
Every of the ac arc wedling machine that generally uses only has an electrode holder now, and usually need weld on the two or more operating points of the above distance of tens of rice that are separated by the job site, in this case, perhaps be equipped with many welding machines, perhaps a welding machine is moved on a plurality of positions, this all can cause the huge waste of time, resource and manpower.In addition, general arc-welding machine does not possess the automatic switch control function of power supply, in case equipment power-on, electrode holder promptly is electriferous state, thereby has the unsafe factor that electric shock accidents may take place.Have, transformer also has open circuit loss when not welding again, so cause waste of energy, acceleration equipment aging.
Main purpose of the present utility model proposes a kind of ac arc wedling machine with two electrode holders with regard to being for overcoming above-mentioned deficiency of the prior art, use such equipment to be implemented in to weld respectively on two operating points separated by a distance and need not mobile welding machine, also can be implemented in and weld simultaneously on two operating points and do not have influence mutually.
Another purpose of the present utility model is to provide a kind of ac arc wedling machine with automatic power switch control function, when using this arc-welding machine, have only when the welder with arc-welding machine after having handed electrode holder just begin the power supply, in case electrode holder is put down, welding machine immediately automatically the outage.
For achieving the above object, the utility model constitutes as follows:
Ac arc wedling machine of the present utility model comprises supply unit and electrode holder unit, wherein: (1) described supply unit have two electric energy output end mouths 0 and 0 '; (2) described electrode holder unit comprise two electrode holders 1 and 1 '; The service cable of (3) two described electric energy output end mouths 0 and 0 ' by separately respectively with two described electrode holders 1 and 1 ' on electric, link; (4) in two electric energy output loops of described supply unit, in series be provided with respectively and promote coil Wi and Wi ', promote coil Wi and Wi ' separately with the main transformer B of described supply unit

Technical scheme is from the above description used two electrode holder ac arc wedling machines of a playscript with stage directions utility model as can be seen, can be on the operating point of two (length that are decided by tie cable) separated by a distance successively or weld simultaneously.This existing arc-welding machine with the equal general power of output is compared, employed material, weight, volume are basic identical, and operating efficiency improves greatly, has improved usage ratio of equipment significantly, when needs carried this equipment and go out to construct, its superiority was just more obvious.
In addition, owing to increased the automatic switch control function of power supply in arc-welding machine, equipment does not have unloaded power consumption when not welding, thus energy savings significantly, and the service life of prolongation equipment.Because equipment no-output voltage when the welder does not hold electrode holder, thereby increased the safety of on-the-spot electricity consumption, especially under wet environment during construction this advantage just more outstanding.
