Intelligent wire feeding machine dynamic characteristic of the present invention is good, traditional inverter type welder need to pass through inverter circuit, transformer, 3 links of rectification could export energy, electric current output can not change and have delay fast, and Intelligent wire feeding machine of the present invention is only just exported energy through the one-level chopper, and electric current can change rapidly and not postpone.And inverter type welder is owing to there being the existence of transformer, and governing speed can not be too fast, otherwise easily cause the main transformer magnetic bias to damage, and Intelligent wire feeding machine of the present invention does not have main transformer, is not afraid of magnetic bias, and governing speed can be very fast.In addition, Intelligent wire feeding machine of the present invention is owing to switching voltage low (30V-90V), and the response speed of switching tube is very fast, and it is very high that frequency can be done, and inverter type welder switching voltage high (500V-600V), it is too high that frequency can not be done.To sum up, the dynamic characteristic of Intelligent wire feeding machine of the present invention is far above inverter type welder, and dynamic characteristic is good, good welding performance.
The matching of the electric current of Intelligent wire feeding machine of the present invention, voltage and wire feed rate is good, the coupling of protecting electric current, voltage and wire feed rate in the weldering at gas is most important, if mate the bad welding performance that does not just have, the tradition wire feeder of welder separates with welding machine, mate one to one through very difficult power supply and the wire-feed motor of guaranteeing after a plurality of intermediate links, and Intelligent wire feeding machine of the present invention is made in power supply and wire-feed motor in the cabinet, can guarantee that electric current, voltage and wire feed rate are in all the time to join state.
The remote good welding performance of Intelligent wire feeding machine of the present invention owing to the resistance of cable, the impact of inductance, if electrode holder line and the control cables of inverter type welder are oversize, will greatly affect welding effect, and especially paired pulses gas guarantor's impact is even more serious.Intelligent wire feeding machine of the present invention is powered by external dc power, and energy storage on internal capacitance, chopper obtains energy on the storage capacitor internally, so the externally fed cable long welding effect that also at all do not affect again.
Intelligent wire feeding machine of the present invention is simple in structure, transless, without high-tension circuit, greatly improved the reliability of equipment.According to statistics, the parts that inversion gas-shielded welder spoilage is the highest are respectively that the control cable damages and main transformer magnetic bias bombing, Intelligent wire feeding machine of the present invention is not only controlled cable but also is not had main transformer, so the most incident these the two kinds of faults of inverter type welder do not exist in Intelligent wire feeding machine of the present invention.
Intelligent wire feeding machine of the present invention is little to the impact of power supply, because the existence of inner storage capacitor, Intelligent wire feeding machine of the present invention is smoothing current from the power supply power taking, output current acute variation unlike inverter type welder, impact to inverter is very large, is easy to cause the damage of inverter.
Inner without high-tension circuit, the potential safety hazard of effectively having avoided the device interior short circuit to cause is especially the most easily leaked electricity when there is metallic dust humid climate or welding machine inside, jeopardizes personal safety.
Externally fed is low-voltage dc power supply, can not injure because of the service cable breakage personnel that cause; And traditional welding machine needs high pressure (220V/380V) power supply, and especially at shipbuilding enterprise, 380 volts of power line breakage will cause on the ship full complement's injures and deaths of getting an electric shock.
Have the expert database of several data interface and welding manner module and welding parameter in the Intelligent wire feeding machine master control borad of the present invention, and have the DEVICENET interface that can connect robot, be convenient to organize and form the welding system of automation.
Intelligent wire feeding machine of the present invention has two gas to protect and dipulse gas is protected welding manner, these two kinds of welding manners all are by the periodic variation wire feed rate, to reach the purpose that changes welding current, weld penetration, weld width and weld bead height, when the peak phase wire feed rate improves, the corresponding raising of welding current, weld penetration, weld width and weld bead height.When the peak point current stage was densely arranged, the scalelike mark effect of rule appearred in weld seam, and weld seam is attractive in appearance.When peak point current stage interval increased, the reinforcement effect of rule appearred in weld seam,
This effect has increased the intensity of weld seam greatly, occasion that originally must the welding multiple tracks, and using only needs behind this welding manner welding once to get final product, and has greatly saved human and material resources and time.
