Knowledge

​Driven by industrial development, the spot welding machine industry is developing rapidly, and the type and quantity of products are constantly increasing, and energy storage spot welding machine is

​The safe use of spot welding machines is something that every worker or ordinary person who uses spot welding machines must know and remember.

​The process means of heating the whole or part of the welding area before the spot welding machine welding is called preheating.

The transformer of the medium frequency inverter spot welding machine is small in weight and volume, and the input power is low, which is convenient to use the transformer to connect the welding tongs

The secondary conductive part adopts the upper insulation method, which can avoid the short circuit accident of the insulation part when the iron filings are supplemented or the lower seat is installe

The adjustment period of the power frequency AC welding machine is longer. For the 50Hz power grid, the welding time adjustment resolution is 20ms.

Structural steel bar spot welding machine is mainly composed of spot welding transformer, electrode arm, lever system, grading switch and cooling system.

There are two types of spot welding machine skid inspection tests, which are non-destructive tests for products and full-wave tests for products mainly used for random inspection.

Electrode arc welding hot welding method is most suitable for castings requiring high quality and good machinability, and electrode arc welding cold welding method is suitable for machined surfaces an

When the welding machine is working, the air circuit and water cooling system are unblocked. The gas shall not contain water. The drainage temperature shall not exceed 40 ℃.

Oil stains and dirt on the upper and lower electrodes must be removed before work. Check the electrical equipment, operating mechanism, cooling system, air system and body shell for leakage.

It is not allowed to operate in the open air in the weather of rain, snow and wind power level 6 or above (including level 6). After rain and snow, the accumulation and snow should be removed before o
