What Is A Welding Generator? The Best Models For Professionals

The welding generator is a portable equipment that combines the function of a generator that generates electricity and a welding machine. It enables welding without being dependent on the power grid and is particularly ideal for construction sites, outdoor work, repairs and mobile welding services.

Operating Principle of Welding Generator

The welding generator generates electricity through an internal combustion engine ( gasoline or diesel) and converts this electricity into the appropriate current to be used in the welding processes. It can also be used to operate power tools and other devices. Welding generators are used in areas without electricity or where a portable welding solution is required. It is an essential piece of equipment for professional welders and industrial workers. Its ability to function as both a power generator and a welding machine provides a great advantage for teams working in the field. To choose the right welding generator, you should consider the requirements of the work and fuel preferences.

The Key Functions of a Welding Generator:

1. Providing Electric Current: Generates direct current (DC) or alternating current (AC) for welding, creating an arc between the electrode and the weld metal.
2. Voltage and Current Control: Improves the quality of the process by providing a constant current or voltage during welding.
3. Working According to Welding Type: There are models suitable for different welding techniques such as MIG, TIG, MMA (electrode arc welding).

Compliance with Welding Method

• MMA (Manual Metal Arc Welding – Electrode Welding): Suitable for general construction and steel work.
• MIG/MAG (Gas Metal Arc Welding): Widely used in the automotive and manufacturing industries.
• TIG (Tungsten Inert Gas Welding): Preferred for stainless steel, aluminum, and thin materials.
• Plasma Cutting Compatible: Generators with integrated plasma cutting functionality are available for cutting operations.

Best Welding Generators for Professionals

For professional welders, choosing the right welding generator is critical to the quality, reliability and efficiency of the work. When choosing, you should consider the following criteria.

What should be considered when choosing a welding generator?

Power Supply Type

- Electric (mains connected): Ideal in stationary workshops and factory environments.

Motorised ( Gasoline/Diesel): Required on construction sites, in the field or for off-grid work.

Current Type

- DC (Direct Current): Provides a more stable welding arc, especially ideal for stainless steel and thin metals.

- AC (Alternating Current): Widely used in general manufacturing and construction.

- AC/DC Combined: Offers flexibility for different metals and welding techniques.Current Type

Welding Current Capacity

- 150-200A generators are sufficient for thin sheet metal and delicate works requiring low current.

- 250-500A generators are preferred for heavy industry and jobs requiring high current.

Portability and Durability

- For workshop use: Fixed and powerful models are preferred.

- For field use: Lightweight, portable and impact resistant inverter welding generators are more suitable.

Brand and Service Support

Choosing from reliable brands and manufacturers that provide spare parts support is advantageous for long-term use.

Types of Welding Generators:

1. Transformer Welding Generator: Uses alternating current (AC), generally low cost.

2. Rectifier Welding Generator: Converts alternating current to direct current (DC), providing a more stable welding process.

3. Inverter Welding Generator: Lightweight and portable, highly efficient and energy saving.

4. Engine Powered Welding Generator: These are generators powered by petrol or diesel engine and suitable for field use.

Considerations for Generators Recommended for Professional Use Below are listed popular and professional welding generator models suitable for various usage scenarios.

For Workshop and Industrial Use
• High efficiency and compatibility between DC (direct current) and AC (alternating current) combined power are important factors when choosing a generator. At the same time, versatile use and suitability for use in heavy industry are among the features to be preferred for use in workshops and industrial areas.

For Construction Site and Mobile Use (Motorised Generator)

 • It is important that it is ideal portable and compatible with AC / DC for the construction site. At the same time, generators with a long-lasting engine suitable for heavy industry and silent, energy-saving generators are preferred in this working environment.

Lightweight and Portable (Inverter Welding Generators)
• For these types of machines, being lightweight and portable is ideal. Compact and durable design, along with superior arc stability and versatile usage, makes inverter technology-based generators the preferred choice.
