Installation and maintenance of mid-frequency spot welder [DCS04]
Spot welder should be properly grounded before use to ensure personal safety. Before powering on the spot welder, use 500V Megohm meter to test the insulation resistance between the high-voltage side and the shell of the welder. Make certain that the insulation resistance is not less than 2.5 megohm before electrifying.

Process parameters of diffusion welding machine [DW03]
Temperature is an important technological parameter of diffusion welding. Small change of temperature will cause great change of diffusion welding speed. In a certain temperature range, the higher the temperature, the faster the diffusion process, and the higher the strength of the obtained joint.

How to adjust the parameters of medium frequency welder during welding? [DCS03]
The welding parameter adjustment of medium frequency welding machine is usually decided by the material and thickness of welding base metal. First step is to determine the shape and size of electrode end face. And then select parameters of electrode pressure, welding current and electrifying time preliminarily.

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.
