DTM Series Intermediate Frequency Spot and Projection Welder
Model: DTM-N-P N:The number of transformer
P: Rated Capacity
e.g.: The Intermediate Frequency spot and projection welder, which rated capacity is 90KVA, is DTM-90.
Features: 1. Intermediate Frequency Direct Current type spot and projection welding machine is the most advanced resistance welding machine. It is widely used in so many industries. The volume of welding transformer is small ,but the output is so large. The integrated welding electrodes used for the automobile industry can appear its advantages. Because the frequency of transformer has been increased from 50/60Hz to 1000Hz, it can reduce the weight of the iron core greatly. The diode used for adjusting the current in the secondary circuit of transformer can transfer the electric energy to the Direct Current to weld product. This can improve the inductance of secondary circuit greatly, which is a major factor leading capacity losing. There is no need to take the inductance into consideration in the Direct Current circuit. So it can minimize the production cost.
2. Power saving:
It can save the energy and improve the power factor, including saving welding on each spo, reducing welding period and reducing production cost. It can make the duty cycle of power supply unit balanced. Its adaptation to the fluctuation of power grid and the decreasing of voltage is more stronger. It can control the electric more precisely and fastly. Comprising with the low Frequency, it has more performance ,and can also analysis the parameter exactly. It can reach the resetting current: The speed of Intermediate Frequency is 20 times than the traditional technology when it adjusting the welding current. The process is more reliable: Adopting the resistance welding with the Direct Current to weld majority of metal, because of its welding effect would be more better. It can also reduce the production processes.
Comparing with the traditional welding machine, it has some advantages ,as follow:
High energy saving: lower welding current and electrode pressure
High quality: comparing with traditional welder .The stability of welding current is better than other models .
3. Low cost: 3 Phase power can input evenly .power factor is high. The lifetime of electrode is 1 time more than traditional ones.
4. High Efficiency: The time to weld one spot is shorter than the traditional ones, so as to improve production speed.
