A thyristor-based welding machine is a type of welding equipment that uses thyristors—semiconductor devices capable of controlling high voltages and currents—to regulate the welding process. This technology allows for precise control of welding parameters such as current and voltage, improving the quality and consistency of welds. Thyristor-based machines are often used in arc welding applications, including TIG and MIG welding, due to their efficiency and ability to handle large power loads. They offer advantages like reduced energy consumption and enhanced welding performance compared to traditional machines.

Yes, resistance welding is used in production welding. It is used extensively in the automotive industry.
Arc. It's where electrical resistance is used to create the heat for the welding process.
Applications of Thyristor(SCR): it is used for temperature control of furnace, in resistance welding as line contactor and in heat control, in electronic ignition of automobiles, in poly phase rectifiers and inverters and in choppers etc...

Arc welding uses an electric arc to melt and join metal pieces together, while resistance welding uses heat generated by the resistance to electric current flow between two metal pieces to join them together. Arc welding is more versatile and can be used for various types of metals, while resistance welding is more suited for high-speed production and is commonly used in automotive and appliance manufacturing.

The percentage of time a welding machine can be used continuously is typically referred to as its duty cycle, which is often expressed as a percentage over a 10-minute period. For example, a machine with a 60% duty cycle can be used for 6 minutes of welding followed by 4 minutes of cooling. Duty cycles vary based on the type of welding machine and its specifications, with common values ranging from 20% to 100%. Always refer to the manufacturer's guidelines for the specific duty cycle of a given machine.
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
