Model: DTM-N-P
DTM: Intermediate frequency inverter spot and projection welder
N: The number of transformer, this model has one transformer.
P: Rated capacity
Feature: Intermediate frequency dc inverter spot and rowing welding machine is the international advanced resistance welder .It is uninersal to used to welding. The volume of welder's transformer is small, but the output is so large. The electrode holder which apply to the automobile industry has appeared the advantges of it. The reason why it has advantages is that the frequency of transformer has increased from 50hz or 60hz to 100hz, that can also decrease the weight of iron core material. The rectifier diodes inside of second electric circuit can transform the power supply to the dc to welding. That can improve the inductance value of second electric circuit, which is also the import factor in leading the power consumption. It almost never considered in the dc circuit. Therefore, it can minimize the cost of production.
Saving power:
Energy saving, improving power factor, including saving each bit of welding energy and shortening time of welding cycle, to decrease the production cost. Make the load of power supply equipment balanced. The conformability for influence of power net and reduction voltage. More accurate and faster current control. Comparised with the lower frequency system, it has more characters, as well as analyzing parameter more accurately. It can reach the presetting current faster: The speed of intermediate frequnency is 20 time than traditional technology when it adjusting the welding current. The process is more reliable: The mojority of metal adopted the resistance welding adopts the dc welding because the welding effect would be more fine, it can also reduce the production process.
Comparison with traditional welder, this mode of welder has advantages of those, as follow:
Energy saving highly: Lower welding current and eletrode voltage;
High-quality: Comparison with traditional welder, its stablity of welding better than others.
Lower cost: 3 phrase power supply balanced input. The power factor is high. The lifetime of electrode is a time more than traditional one.
High efficiency: The time to welding one spot completely is less than traditional welder. The speed of production would be improved.
