Microprocessor or PLD can be used to be programmed to.User has only to set the diameter parameters of welding rod, so that it may
To obtain the welding effect of specialty, it is achieved the intelligentized control method of inversion Manual electric welding machine, there is the display interface of close friend with easily
Operate with, it is not necessary to complex parameters sets, and the welder not possessing welding specialty technology can conveniently operate with, meet
The welding operation demand of welding fan.
The invention has the beneficial effects as follows: this welding meets amateur welding personnel and inversion welding machine can be used to carry out manual welding,
High-caliber welding quality can be obtained.Welding current is the important parameter of welding procedure, determines welding quality, but welding current
Determination be difficult to very much for amateur welding personnel, but reach welding effect by indirect selections core diameter
Relatively the most.First primarily determine that welding current according to the core diameter selected, in welding process, detect weldering in real time
Connect output voltage, it may be judged whether satisfied by the relation of the weldingvoltage U and electric current I of welding experience, thus adjust welding current
Size, uses Power Electronic Technique, microprocessor technology and automatic control technology to design, it is achieved inversion Manual electric welding machine
