Abstract
The utility model relates to a pair of auto-adjusting weld handle pliers, which mainly solves the problem inconvenient current regulation of an existing electric welder. A resistor changing device is arranged on the weld handle pliers; the weld handle pliers can be connected with two excitation wires of a DC electric generator; two excitation wires are connected in series together thorough the resistor changing device. The utility model has good application foreground in the field of electric welders.
Description
The utility model relates to weld handle plier.
At present, existing dc welding machine all is by porcelain dish resistance adjustment electric current, like this when the people from electric welding machine place far away or during the welding of high-altitude, undoubtedly can be pretty troublesome if regulate electric current.
The purpose of this utility model is to provide a kind of weld handle plier that can regulate the electric welding machine electric current.
The technical solution of the utility model: be equipped with rheostat on the weld handle plier, weld handle plier also is connected to two excitation wire of dc generator, and two excitation wire are serially connected through rheostat.So only need to regulate rheostat, can change the exciting current of dc generator, thereby reach the purpose of regulating the electric welding machine electric current.
Advantage of the present utility model: owing to the adjusting that on weld handle plier, can realize, so greatly facilitate use to the electric welding machine electric current.
Narrate embodiment of the present utility model in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural representation.
During enforcement, rheostat is to constitute like this, level is equipped with hollow porcelain rod resistance 2 on the weld handle plier afterbody, the metal frame 6 that has insulator cap 8 contacts with hollow porcelain rod resistance through metal film conductor 4, and can do horizontal direction along it and slide, metal film conductor 4 is connected with Metal Contact sheet 7 through conductor 5, and hollow porcelain rod resistance 2 tops are equipped with metallic conductor plate 10, Metal Contact sheet 7 contacts with metallic conductor plate 10, and can do horizontal direction along it and slide.The metallic conductor plate 10 outer insulation boards 11 that are equipped with.Two excitation wire 12 of dc generator are received on the terminal plate 9, draw two lines on the terminal plate 9 and receive respectively on the resistance wire 3 and metallic conductor plate 10 of hollow porcelain rod resistance.Also the excitation wire 12 of original single core electrode holder line 1 and two dc generators can be made the electrode holder line of one three core during enforcement.During work, the exciting current of dc generator enters the binding post of terminal plate 9 through an excitation wire 12, the lead that electric current is drawn through terminal plate 9, resistance wire 3, metal film conductor 4, conductor 5, contact chip 7, metallic conductor plate 10, terminal plate, after another root of excitation wire 12 flows out to dc generator.When sliding metal frame 6, electric current the length of resistance wire 3 of process change thereupon, thereby change exciting current, reach the purpose of regulating the dc generator electric current.When electric welding machine need not use, metal frame 6 is slided into the position that does not have resistance wire 3, exciting current promptly is cut off, thereby dc generator is quit work.The utility model also can be used on the silicon rectifier electric welding machine.
Claims (2)
1, a kind of self-regulated weld handle plier that is connected to the electrode holder line is characterized in that: be equipped with rheostat on the weld handle plier, weld handle plier also is connected to two excitation wire of dc generator, and two excitation wire are serially connected through rheostat.
2, self-regulated weld handle plier according to claim 1, it is characterized in that: rheostat is to constitute like this, level is equipped with hollow porcelain rod resistance on the weld handle plier afterbody, the metal frame that has insulator cap contacts with hollow porcelain rod resistance through the metal film conductor, and can do horizontal direction along it and slide, the metal film conductor is connected with the Metal Contact sheet through conductor, and hollow porcelain rod resistance top is equipped with the metallic conductor plate, the Metal Contact sheet contacts with the metallic conductor plate, and can do horizontal direction along it and slide.
