The specific embodiment
Describe the Automatic adjustment method of unified weldingvoltage fine setting scope of the present invention in detail below in conjunction with accompanying drawing embodiment.On parts same as the prior art, give identical Reference numeral.
As Fig. 1, Fig. 2, shown in Figure 3, at first, set the welding current value by remote controller 1, the given signal of welding current of the welding current value that this interval scale sets is sent to the A/D converter of being located on the source of welding current 22 2 by remote controller cable 44, after carrying out analog digital conversion by this A/D converter 2, signal is inputed in the controller 3 the control core that this controller 3 is whole welding systems.After control program in this controller 3 is discerned the given signal of above-mentioned welding current, size according to the welding current value that sets is tabled look-up, provide standard welding voltage value that should the welding current value and this standard welding voltage value be presented on the display screen of being located on the source of welding current 22 (not shown), give simultaneously as shown in Figure 4, based on the weldingvoltage fine setting scope of given standard welding voltage value.Wherein, that above-mentioned table comprises is 1 that obtain based on following empirical equation, the matching list of welding current value and standard welding voltage value and based on the fine setting scope table of this standard welding voltage value, and all is to be stored on the memory in advance.At this moment, the weldingvoltage on the remote controller 1 is adjusted potentiometer on normal place.
Empirical equation 1
The occasion of welding current below 300A:
Weldingvoltage (V)=0.04 * welding current (I)+16 ± 1.5
The occasion of welding current more than 300A:
Weldingvoltage (V)=0.04 * welding current (I)+20 ± 2.0
In welding process, when the operator thinks that standard welding voltage value and welding current value are not to mate very much, during the stable weld job that promptly can not carry out, to finely tune, the weldingvoltage of promptly regulating on the remote controller 1 is adjusted potentiometer, subtract adjustment from above-mentioned normal place left-handed transferring to, transfer to from above-mentioned normal place dextrorotation and add adjustment.For example, when the operator has carried out subtracting adjustment, the given signal of weldingvoltage that representative subtracts adjusted welding voltage value is sent to A/D converter 2 by remote controller cable 44, carry out the analog digital conversion equally by this A/D converter after, this signal is inputed in the controller 3.Relatively subtract adjusted welding voltage value and based on the fine setting scope of given standard welding voltage value by controller 3.Comparative result, if when subtracting adjusted welding voltage value and being in the described fine setting scope, controller 3 is in statu quo exported to D/A converter 4 with the given signal of weldingvoltage that representative subtracts adjusted welding voltage value, D/A converter 4 carries out exporting to IGCT triggering signal generation circuit 5 after the digital-to-analogue conversion, this IGCT triggering signal produces circuit 5 control IGCTs 6, by the IGCT 6 control source of welding current 22 (3 cross streams power supplys 221, main transformer 222) output, finally export the weldingvoltage corresponding, thereby carry out stable weld job with subtracting adjusted welding voltage value.Above-mentioned comparative result, if when subtracting adjusted welding voltage value and having exceeded fine setting scope based on given standard welding voltage value, during promptly less than the minimum of a value in the fine setting scope, the given signal of weldingvoltage of this minimum of a value is represented in controller 3 outputs, and the final output weldingvoltage corresponding with this minimum of a value.In like manner, adding when adjusting, when adding adjusted welding voltage value and having exceeded fine setting scope based on given standard welding voltage value, during promptly greater than the maximum in the fine setting scope, the final output weldingvoltage corresponding with this maximum.Like this, no matter how the operator regulates weldingvoltage is adjusted potentiometer, and welding voltage value all in above-mentioned fine setting scope, therefore can guarantee the stable welding of electric welding machine.
The fine setting scope of the standard welding voltage value of above-mentioned corresponding different welding currents is that the soldering test by reality obtains, and therefore, it is stable that the fine setting scope of the standard welding voltage value that the controller computation of table lookup draws can be guaranteed to weld.With rated current 500A type is example, when carrying out unified adjusting, when setting and regulate the welding current value, except that welding voltage value mates the variation with the variation of welding current value automatically, for example, when the welding current value is 200A, be 19V～30V to the suitable fine setting scope of standard welding voltage value 24V that should the welding current value.In 60～500A welding current scope that this electric welding machine covered, the fine setting scope trend of accordingly suitable standard welding voltage value is shown in hacures scope among Fig. 4, and three curves wherein are respectively the maximum curve B of standard welding voltage value curve A, weldingvoltage fine setting scope, the minimum of a value curve C of weldingvoltage fine setting scope.
As mentioned above, according to the present invention, the adjustable range of unified weldingvoltage is that the variation with the welding current value changes, when welding current value hour, the fine setting scope is little, when increasing welding current, the corresponding increase of fine setting scope, and the welding voltage value that makes final output all is in the fine setting scope that can stablize welding, therefore no matter how the operator regulates weldingvoltage is adjusted the stable welding that potentiometer can both guarantee electric welding machine, be that the operator can finely tune welding voltage value according to the welded piece actual needs, and in whole fine setting scope, all can keep stable welding.
