resistance welding

Resistance welding machine also named spot welding machine, the principle is after the combination of the metal workpieces, applying appropriate pressure, using the welding current to generate the heat from the electrodes and the workpieces resistance, the heat may melt the metal and get a welding joint.

There are five main factors of resistance welding:1, welding current;2,welding time;3,welding pressure;4,electrode material;5,electrode dimension.

The power supply of resistance welding also has been developed from capacitor energy storage/AC *0Hz to inverter DC type to crystal type.

We are making inverter DC type, that means *0% power less than capacitor energy storage/AC *0Hz type, and much more precise and stability, can reduce the reject rate, can be more powerful when high speed welding.

1, Resistance welding power supply Specifications:

PS: We have the independent property rights of the power supply, we can make customized power supply.

      As the voltage,we can also provide **0V/**0V*3/**0V*3/**0V.etc

1,IGBT inverter with 4kHz frequency.

2,Three step welding with upslopw and downslope.

3,High precisely welding control system.

4,Constant-current control, constant-voltage control, constant power control, constant pulse width control.

5,Upper and lower monitor of the current or the voltage etc.

6,Easily operating,.

7,The power supply can be easily used on a automatic machine, and automatic adjust the current to keep the tip heat.

2, Principle of inverter resistance welding power supply and the current waveform of capacitor type/AC type/inverter type/crystal type
