Description
Technical field
The invention belongs to welding field, particularly relate to a kind of electric welding machine。
Background technology
Weld job is clearly decided to be job that requires special skills, because this operation has great harm for operator, other people, the safety devices of peripheral facilities, trigger, initiation fire and equipment scaling loss are all the casualties and the property loss accident that are easiest in weld job occur。For electrode holders and welding cable, because it has ambulant handling characteristics, and be in weld job, contact the most charged equipment with operator, big electric current flows through from electrode holders handle, electric welder and the relevant personnel are likely to contact these equipment and relevant charged object at any time, as changed welding rod, arrange weldment, move cable, the operant activity such as handling electrode holders, operator will contact them directly or indirectly, also have and many touch unintentionally or unexpectedly, undefended owing to being milli, so being also the most dangerous。
Electric welding machine is the solder and materials to be welded that utilize the high-temperature electric arc that positive and negative polarities produce when instantaneous short circuit to come on consumable electrode, reaches the purpose making them combine。Structure is very simple, it is simply that a powerful transformator, and electric welding machine generally can be divided into two kinds by out-put supply kind, and a kind of is alternating current power supply；One is galvanic。Being that the principle utilizing inductance is made, inductance value can produce huge change in voltage when switching on and off, and the solder utilizing the high-voltage arc that positive and negative polarities produce when instantaneous short circuit to come on consumable electrode reaches the purpose making them combine。Performance, electric welding machine is the special transformer with flat characteristic or decline external characteristics, and 220V and 380V alternating current becomes exchange or the direct current output of low-voltage。Electric welding machine generally can be divided into two kinds by out-put supply kind, and a kind of is alternating current power supply；One is galvanic。The electric welding machine of direct current is it may be said that be also a powerful commutator, divide positive and negative polarities, during alternating current input, after transformator transformation, then by rectifier rectification, then output has the power supply of decline external characteristics, outfan can produce huge change in voltage when switching on and off, ignite electric arc when instantaneous short circuit at the two poles of the earth, utilizes the electric arc produced to come consumable electrode and wlding, and cooling reaches the purpose making them combine later。Welding transformer has the feature of self, and external characteristics is exactly the characteristic that voltage sharply declines after welding rod ignites。
220V alternating current is become low-voltage by electric welding machine, the power supply of big electric current can be direct current can also be exchange。Welding transformer has the feature of self, it is simply that have the characteristic that voltage sharply declines。After welding rod ignites, voltage declines, and secondary coil also has tap-change voltage, and also useful iron core regulates simultaneously。Electric welding machine is usually a powerful transformator, system utilizes the principle of inductance to make, inductance value can produce huge change in voltage when switching on and off, the solder utilizing the high-voltage arc that positive and negative polarities produce when instantaneous short circuit to come on consumable electrode, reaches the purpose making them combine。Between welding rod and workpiece, apply voltage, by scratching or contact striking electric arc, melt welding rod and heating mother metal with the energy of electric arc。
The general connection disconnecting link of conventional A.C. welder or air break controller, as shown in Figure 1, when close valve knife-like switch QS time, electric welding machine is started working, when leave behind valve knife-like switch QS time, electric welding machine quits work, this circuit makes the most frequently used, but safe not, it is impossible to remote-controlled operation。
After packaging opened by welding rod, direct and atmosphere, if rainy day or the weather of humidity, electrode coating easily absorbs the moisture in air, and the welding rod of the moisture absorption is when welding, not only striking difficulty, and welding technological properties is had and bad impact, it is easy to cause security incident。
