Product Description
The portable spot welding machine uses the resistance heat generated by the current flowing through the weldment as a heat source for welding under pressure. Mainly used for spot welding of low-carbon steel parts of thin plate structures.
Portable spot welding machines are generally suspended in the air and connected to the welding tongs through flexible cables. The welding tongs of the portable spot welding machine have various structural forms to choose from, so the portable spot welding machine has a strong adaptability for large workpieces that are inconvenient to move, workpieces with complex shapes, or workpieces that must be stuck on the fixture for spot welding. In automobile body spot welding, the spot welding process for large sheet metal boxes has a wide range of applications and is an indispensable welding equipment.

Mian Features
1. The portable spot welding machine combines a welding transformer with a welding clamp, and has an aluminum body, featuring small size, high output, high efficiency, energy conservation, and portability. During operation, the portable spot welder can easily achieve 360 degree rotation in both horizontal and vertical directions.
2.The portable spot welding machine consists of welding tongs, welding transformer, welding controller, water cooling system, pneumatic pressurization system, (and suspension device), etc. Compact structure, convenient maintenance, small size, light weight, greatly reducing the labor intensity of workers and greatly saving energy consumption.
3.The electrode arm of the portable spot welding machine adopts high-quality chromium zirconium copper (CuCrZr-1), ensuring the stability of welding performance, the service life of the welding machine, and the strength of the electrode arm.
4.During welding, the heating time is short, the heat is concentrated, and there is no electric arc, spark splash, welding slag, fusion welding accumulation, and thermal deformation of the weldment. In addition, after the innovation of the welding machine, the diameter of the gas path system is increased, so not only the welding productivity is high, but also the appearance of the weldment is beautiful and the quality is good.
5. Welding is accomplished using the proper combination of resistance heat and mechanical force, so it is possible to obtain high-strength high-quality solder joints for the weld nuggets of the weldment.
5.Due to the simple welding process, without the need for filler materials, solvents, and shielding gas, the cost is low.
6.Due to the high current density and high temperature of the solder joint of the weldment, the precise control of the power-on time by the welding machine controller allows the solder joint to obtain a reproducible nugget size, which can adapt to the welding of multiple types of the same or different metals and coated steel plates.
