Description
The utility model relates to a kind of direct-current arc welding equipment, especially a kind of DC arc welder.
The output of present DC arc welder generally all is connected to filter reactor.The inductance value size of this reactor has determined its stored energy capacitance, and the dynamic characteristic of butt welding machine and little current capability influence simultaneously is bigger.In addition, in present normally used various welding rods, the cellulose welding rod is used for pipeline welding in a large number, but because its compositions of surfacing metal is more special, the physical characteristic of welding arc, form of droplet transfer or the like and lime-titania type, ferrotianium type, hydrogen controlled electrode (the following common welding rod that all abbreviates as) are different, thereby the cellulose welding rod is different to the requirement of DC arc welder with common welding rod.Wherein one of main difference point is, the cellulose welding rod needs bigger filter reactor, so that when little electric current welding electric current can be kept continuously, that is blow-out and current interruption does not take place when guaranteeing in the pipeline welding process with little electric current backing welding.Inductance value required when the inductance value of the reactor that need this moment welds than common welding rod is a lot of greatly.This just means that for a DC arc welder, its inductance value is in case after determining, just be difficult to take into account the welding demand of common welding rod and cellulose welding rod.The way of passing through is at present, and electric welding machine manufacturer produces different DC arc welders, and the inductance value of the reactor that it had varies in size, and is respectively applied for common welding rod and cellulose welding rod.That is to say,, weld the cellulose welding rod again, just need to buy two different welding machines, thereby cause the waste of fund if the electric welding machine user should weld common welding rod.
The purpose of this utility model is to overcome above-mentioned defective, a kind of DC arc welder is provided, wherein, can select the inductance value of this DC arc welder as required, make it both to can be used for the cellulose welding rod, also can be used for common welding rod, promptly, realize common welding rod and cellulose welding rod dual-purpose with a welding machine, thus the waste of minimizing fund, and easy to use.
To achieve these goals, the utility model provides a kind of DC arc welder, it comprises power supply major loop, control loop, filter reactor and casing, described power supply major loop has one and is used for the output that is connected with the mother metal cable, one end of described filter reactor links to each other with major loop, the other end is the filter reactor output, this filter reactor output is used for being connected with the soldering turret cable, wherein, the output of described filter reactor has two, one of them is the big inductance quantity output, and another is a small inductor amount output; Filter reactor adopts the centre tap formula, promptly, adopt and the corresponding big inductance quantity reactor of cellulose welding rod, the output end of this big inductance quantity reactor is the big inductance quantity output, suitable number of turns tap from this reactor, the output end of this tap is a small inductor amount output, and the required inductance of the described suitable number of turns and common welding rod is corresponding; The output of described power supply major loop and the output of described filter reactor are quick socket.
In DC arc welder of the present utility model, the output of filter reactor has two, and one of them is the big inductance quantity output, and another is a small inductor amount output.In actual welding, the mother metal cable is linked to each other with the major loop output, and the soldering turret cable can be selected to link to each other with big inductance quantity output or small inductor amount output according to the difference of used welding rod, that is, can between large and small inductance value output, switch arbitrarily; When using the cellulose welding rod, the soldering turret cable is linked to each other with the big inductance quantity output, can satisfy cellulose welding rod when welding required than big inductance quantity, when using common welding rod, the soldering turret cable is linked to each other with small inductor amount output, can carry out the welding of common welding rod.Like this, by the link position of conversion electrode holders cable and filter reactor, when common welding rod or the welding of cellulose welding rod, all can obtain good welding effect, realize a tractor serves several purposes, thereby avoided waste, and, output adopts quick socket, and is more convenient to use.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the structural representation of DC arc welder of the present utility model, has wherein omitted casing;
Fig. 2 is the output connection diagram of DC arc welder of the present utility model.
Referring to Fig. 1, a kind of DC arc welder, it comprises power supply major loop 1, control loop 2, filter reactor 3 and casing (not shown), described power supply major loop 1 has one and is used for the output 7 that is connected with the mother metal cable, one end of described filter reactor 3 links to each other with major loop, the other end is the filter reactor output, this filter reactor output is used for being connected with the soldering turret cable, wherein, the output of described filter reactor 3 has two, one of them is a big inductance quantity output 6, and another is a small inductor amount output 5.
Wherein, described filter reactor 3 adopts and the corresponding big inductance quantity reactor of cellulose welding rod, the output end of this big inductance quantity reactor is a big inductance quantity output 6, suitable number of turns tap from this reactor, the output end of this tap 8 is a small inductor amount output 5, and the required inductance of the described suitable number of turns and common welding rod is corresponding.
As shown in Figure 2, in use switch for the convenience of the user, the output 7 of described power supply major loop 1 and the output of described filter reactor 35,6 all can adopt quick socket 13 of the prior art, it matches with the quick plug 14 of soldering turret cable, thereby can switch more easily.By the link position of conversion electrode holders cable 10 and the quick socket of output, when common welding rod or the welding of cellulose welding rod, all can obtain good welding effect, realized a tractor serves several purposes, and easy to use.
