Four stages of welding time for intermediate frequency spot welder [DCS02]
We know that there is a complete course for Spot Welder to finish each welding joint. The course can be divided as pre-pressure, welding, holding, resting total four stages. Each stage lasts a certain time, namely pre-pressure time, welding time, holding time, and resting time. These four stages are indispensable to the quality of spot welding.

Advantages of intermediate frequency welding machine [DCS01]
The welding principle of intermediate frequency welding machine is
to press the welded workpiece between two electrodes
an electric current passes through the contact surface of the metal workpiece and the adjacent area
Meanwhile resistance heat emerges, heating the metal contact to the melting or plastic state, forming a metal bond.

Composition of energy storage spot welder [CD02]
Simply speaking, the working principle of energy storage spot welding machine is to use capacitor energy storage, and then to release electric energy to the welding site through high current, and make it instantaneous heated and melted, so as to achieve the purpose of spot welding.

What are the characteristics and advantages of capacitor energy storage spot welder? [CD0１]
The capacitor energy storage welding machine is used to charge the capacitor after the alternating current is rectified by the rectifier, and the stored electric energy is converted into low-voltage, energy-concentrated and stable pulse current by the welding transformer. The resistance heat is generated through the contact point of the welding work piece, and the metal piece is fused instantaneously.
