The CEA ARC 403 welder is a solid and versatile machine, ideal for professional welding needs and suitable for use in industrial and construction environments. This model belongs to the CEA ARC series, known for its robustness and reliability in steel maintenance and construction.

Composition and Mechanical Characteristics
The CEA ARC 403 is equipped with a powerful three-phase motor that allows for efficient operation with electrodes ranging from 2 to 6 mm in diameter. Thanks to the continuous regulation of the welding current via a magnetic shunt, it is able to maintain a stable and controlled welding arc, essential for achieving high-quality results even in difficult working conditions. Its wide current regulation range (from 55 to 250 A) allows for easy welding of a wide range of materials, including carbon steels, stainless steels, and special alloys.

Dimensions and Weight
This welder's compact size makes it easy to maneuver despite its power. Its overall dimensions are approximately 880 mm long, 425 mm wide, and 690 mm high, with a weight of approximately 95 kg. This makes it easy to move around the work site thanks to its convenient wheels and handles. These features make it ideal for working in confined spaces or on construction sites.

Performance and Power
The ARC 403 is powered by a 230/400 V voltage and has a power consumption of 26.8 kVA. The welder is designed to guarantee a maximum current of 200 A at 100% duty cycle, with capacities of 260 A at 60% and 350 A at 35%. The secondary open-circuit voltage of 71 V allows for precise and uniform welding on various types of materials.

Operation and Maintenance Procedure
The CEA ARC 403 is very intuitive to operate: simply select the electrode type and set the appropriate welding current, and the welding arc will automatically stabilize thanks to the magnetic shunt system. Maintenance of this machine is relatively simple and focuses on regularly cleaning the terminals and checking the condition of the electrodes. It is also essential to check the cooling system and electrical insulation, especially if the machine has been used for long welding sessions.

Safety and Compliance Regulations
Although no CE regulations are specified for this model, it is always possible to adapt a used welder to current safety regulations (e.g., CEI 64-8 for electrical equipment) through a thorough inspection of the insulation and protection systems. The presence of a safety switch for voltage selection and its compact size minimize risks during use, provided it is regularly maintained.

Areas of Use:
This welder is particularly suitable for heavy carpentry work, industrial maintenance, shipbuilding, and steel welding. The ARC 403 model is an ideal tool for professional welders working in harsh environments, where a powerful and reliable machine is required. Furthermore, thanks to its robustness and adaptability to different types of electrodes, it is widely used on construction sites and in welding workshops.

Why Buying a Used CEA ARC 403 Welder Is Worth It?
Buying a used CEA ARC 403 welder is a smart choice for those seeking a high-quality product at an affordable price. CEA welders are built to last, and a used machine in good condition can still provide excellent performance for many years. The ARC 403, in particular, thanks to its robustness and ease of maintenance, represents an opportunity to obtain a high-quality tool at a fraction of the cost of a new one.

In conclusion, the CEA ARC 403 is a versatile, powerful, and durable welder, ideal for those who need a reliable machine for arc welding. With proper use and maintenance, it can provide excellent performance for years, making it an ideal choice for second-hand purchases.
