Arc welding machine, also known as arc welding transformer, is a special type of transformer that turns the AC voltage of the network voltage into a low-voltage AC suitable for arc welding. It consists of the main transformer and the required adjusting parts and indicating devices.
Arc welding machine mainly moving core type, the same type and moving coil three. It has the advantages of simple structure, easy to repair, low cost and high efficiency. However, the current waveform is a sine wave, the output is AC drop characteristics, the arc stability is poor, the power factor is low, but the magnetic partial blowing phenomenon is seldom produced, and the no-load loss is small, which is generally used in hand arc welding, submerged arc welding and TIG welding methods.
Features and uses
The welder with easy operation and maintenance, noise and vibration characteristics.
Can be used as high carbon steel, alloy steel, copper and cast iron and other higher technical requirements of the welding.
Can be used for all brands of AC or DC arc welding by hand;
Steplessly adjust the welding current, current regulation easy to ensure arc stability under different welding conditions;
Suitable for welding mild steel, medium carbon steel, low alloy steel and castings.
