Air Operated Pneumatic Three - phase DC Welding Machine For Hardware

Air Operated Pneumatic Three-phase DC Projection Welding Machine

DESCRIPTION

Medium frequency inverter spot welding machine is an advanced welding machine with wide application. The welding transformer is in small size but the output energy is large. Three-phase AC will be converted into DC after being rectified. Then the DC will be converted into medium frequency 1000 Hz square wave to be connected to primary welding transformer through the inverter circuit which is composed of IGBT. The MF square wave will become small pulse DC to the electrode for welding work piece through the depressurization and rectifying process in the welding transformer. The inverter will adjust the duty ratio of IGBT through the feedback primary or secondary current so as to achieve constant current of the welding process.

Compared with the normal AC controller, MF controller has the following advantages:

1. The current in secondary welding loop is DC. Dramatically reduce the impact to the welding current due to the inductive reactance in secondary loop when conducting welding to the work piece.

2. The weight of transformer is reduced greatly. It is light and convenient. The weight and size of the MF transformer is only 1/3 of the AC type transformer. Suitable for robot welding system.

3. Prolong the service life of electrode

4. Be able to weld material like aluminum, galvanized steel, etc. with good welding performance.

5. Especially suitable for three-layer plate welding, ultrathin material welding and precision welding.

6. Less splashes.

7. Increase control of current and welding quality.

SPECIFICATION

***********************************************************************************************

We can design and manufacture the welding equipment according to your request/drawing, contact us please, we will offer you a suit solution and support you to success.

APPLICATION

Especially suitable for welding metals such as copper, aluminum, nickel, molybdenum, tungsten, manganese, gold, silver and other non-ferrous metals and precious metals precision. Widely applied to welding battery, lighting electric resource automobile, medical apparatus and instruments, photoelectric communication, micro motor as well as requested chip inductor with high temperature enameled round wire/ extra fine wire (minimum size can be 0.02mm),wire rope, metal wire, nickel cup, can cutting wire and welding, CCFL field, fuse, lamp filament.

FEATURE

1. The current in secondary welding loop is DC. Dramatically reduce the impact to the welding current due to the inductive reactance in secondary loop when conducting welding to the work piece.

2. Three-phase balanced load can reduce the requirement to the power supply system. The power factor is close to 1. No electrical inductance, so no need to adjust the power factor.

3. Eradicate the contamination to the power supply. It is a kind of environmentally friendly welding method. No need to provide power independently. It is able to be used together with robotic welding system.

4. Reduce power consumption, energy saving. Reduce the requirement of cables and lots of maintenance cost.

5. The weight of transformer is reduced greatly. It is light and convenient. The weight and size of the MF transformer is only 1/3 of the AC type transformer. Suitable for robot welding system.

6. Increase the heat input efficiency. The output of welding transformer is DC voltage, without the disturbance of inductance. Pure DC has no defect of zero passage. The efficiency of heat is enhanced dramatically.
