Product Description

The portable spot welding machine integrates related devices such as welding transformers, cylinders, solenoid valves, water and gas distributors, rotating rings and suspension rods, balance systems, and control handles. The electrical main circuit adopts a single-phase AC 380V/50HZ input, which is fed through the controllable silicon in the controller and then to the transformer. After being reduced by the transformer, the secondary output is low voltage (4.75-10V) and large current (12-20KA) between the electrodes. The controller adjusts the conduction angle of the controllable silicon to adjust the output current of the transformer to meet the requirements of welding specifications.

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

Features:

1. Small, easy to operate and save power/ Convenient operation and power-saving.

2. The structure is compact and is easy to maintenance/Simple structure and convenient maintenance/Compact structure and friendly maintenance.

3. The portable spot welders can rotate 360°as the turntable is configured with bearings.

4. Customized welding tongs, the longest welding arm is 1300mm and the shortest is 220mm.

5. The body structure is strong and resistant to damage.

Application:

The portable spot welding machine is widely used in automobile manufacturing, maintenance, household appliances, doors and Windows, agriculture, construction steel and other metal manufacturing industries.

Welding Principle Of Electric Resistance Welding

The weldment is pressed between two columnar electrodes and heated by electricity, so that the weldment melts at the contact and forms a nugget. Then power off, the weldment is solidified and crystallized under pressure to form a dense welding spot. Spot welding is suitable for welding thin plate (lap) and steel bar. It is widely used in the production of automobile, aircraft, electronics, instruments and daily necessities.
