It depends on several spot welders. If 2 spot welders can do that. Obviously, what you want is 1 spot welding machines to discharge at the same time, that depends on the structure and welding requirements, low requirements, you can. As a spot welding equipment manufacturers certainly do not agree to do so, the welding effect is unstable, is the first big. To be efficient, welding quality requires more investment in equipment. Why not? In the case of 1 sets of spot welding machine, it is difficult to achieve the design of solder joints consistent.s
The main difference between medium frequency inverter welding machine and high frequency inverter welder is the difference of operation frequency. Medium frequency inverter welding machine is generally 800-1000 weeks work frequency; high frequency inverter welding machine is generally 1000-25000 weeks work frequency.Inverter spot welder is characterized by small power and high efficiency. The reason for the small power is that the battery can solve the problem of spot welding without AC power supply. But power is impossible because it is powered by batteries. Most of them are compact and portable, and frequency conversion is adopted to improve the efficiency of power conversion. In general, the higher the frequency, the higher the efficiency of inverter conversion, the higher the cut-off frequency requirements of the inverter. But considering the work environment, interference, radiation and other issues, nor is the frequency of work, the higher the better election.At present, there are two kinds of inverter, spot welder, frequency and high frequency. Intermediate frequency machine operation frequency 1000HZ (week) or so. High frequency machine operating frequency 4000HZ (week) or so, the highest 25000HZ (week) products.s
Welding machine is to use the positive and negative poles in an instant short circuit when the high temperature arc to melt welding electrode on the solder and welding material, to achieve the purpose of combining them. The structure of the electric welding machine is very simple. To speak plainly, it is a high-power transformer. It can change the 220V alternating current into low voltage, high current power supply. It can be DC or AC. Welding transformer has its own characteristics, that is, a sharp drop in voltage characteristics. The voltage drop in the ignition electrode, adjusting working voltage in electric welder,... In addition to a 220/380 voltage conversion, there are two secondary coil tap changing voltage, but also useful to adjust the core, adjustable iron core... Electric welding machine is generally a large power transformer, the Department made the principle of the inductor inductance, will produce a huge change in voltage is switched on and off, resulting in high voltage arc when sudden short-circuit the use of positive and negative poles to melt the solder wire. To achieve the purpose of combining them. A voltage is applied between the electrode and the workpiece. By welding or contacting the ignition arc, the electrode is welded and the parent material is heated with the energy of the arc.s
It seems that to solve your problem is to let you understand the principle of the transformer OK, it is mainly controlled by the number of lines, usually expressed by N, that is, through the primary number of bundle and secondary number of changes in the bundle.s
Dissimilar materials with different melting points are more difficult to weld, and they are galvanized sheet (zinc layer of various thickness). Try with soft specifications. The first discharge time is 8 cycles, and the 6 cycle between the second discharges is tried.s
Must be affected, such as: 3 current acting on one electrode head to ensure the stability of the solder joint. How much current does the three electrodes need to operate at the same time? Can the current, voltage, air pressure be stable? Can the height of the electrode guarantee the same height? If not, there is a gap when pressed, easy to breakdown.s
