Product Description

The portable spot welding machine adopts a modular design, integrating relevant devices such as welding transformers, air cylinders, electromagnetic valves, water and gas distributors, rotating rings and suspenders, balancing systems, and control handles. The main electrical circuit uses a three-phase AC 380V/50HZ input. After entering the intermediate frequency inverter resistance welding controller, the three-phase AC power becomes DC power through a rectification circuit, and then passes through an inverter circuit composed of power switching devices (IGBTs) to become intermediate frequency 1KHZ AC square wave output. After being reduced by a transformer, the three-phase AC power is rectified into DC power supply to the electrode for welding the workpiece. The intermediate frequency inverter controller uses current feedback and pulse width modulation (PWM) to obtain stable current output to meet the requirements of welding specifications.

♦ Distance,angle and length of welding arm can be made according to customers' requests.

Features:

1. Three-phase power input, high operating frequency, low transformer loss, and significant energy saving effect

2. The transformer can be up to 300kva, the transformer secondary tube brand is ABB

3. Can weld high-strength plate, aluminum, galvanized metal and other materials, having a good welding effect

4. Welding current is DC, with high control accuracy, stable output current, low inductance and little spatter

5. Fully enclosed plastic shell is safer

6. The controller can control two welding tongs

7. Self-adaptive to the thickness of workpiece plate

Application:

The portable spot welding machine is widely used in the automobile, motorcycle, aviation, sheet metal structural components, medical equipment, light industrial machinery, household appliances and other fields. And it can welding carbon steel sheet, coated steel sheet, stainless steel sheet, aluminum sheet metal.
