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. By adjusting the size of the thyristor (IGBT) through a controller, the output current of the transformer can be adjusted to meet the requirements of welding specifications.

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.
Welding Process
The main working process of portable spot welding machine is composed of four basic procedures: pressurization, welding, maintenance and rest, and additional procedures can be added if necessary.
