Paton ProMIG-350-(15-4)

The ProMIG-350 incorporates cutting-edge technology to enhance your welding experience. This welder features precise voltage ramp up and ramp down times, as well as wire feed speed control, ensuring smooth transitions and minimizing spatter.

Our welder is a device for professional use, designed for semi-automatic welding (MIG/MAG), manual arc welding (MMA), TIG DC, in shielding gases and mixtures thereof. ProMIG-350 has an all-digital way to manage, thereby ensuring its versatility and opportunities to fine tune the welding conditions.

Expectancy increased load on the rated current to 350A, allows any electrode diameter from 1.6 mm to 6 mm, and the semi-solid welding wire with a diameter of 0.6 to 1.2 mm. Due doublecase execution, a current source can be easily separated from the wire supply unit, which greatly improves the portability and usability in MMA and TIG modes.


Paton ProMIG-Series

The ProMIG-350 is part of Paton’s Pro series, which stands for the highest quality and advanced technology designed for professionals.

Pro series welders are known for their exceptional durability, performance, and reliability, making them the perfect choice for intensive use in demanding environments. With top-tier components such as Kendeil capacitors, in-house produced copper transformers, and Infineon transistors, the ProMIG-350 ensures outstanding welding results every time.

Robust construction and IP33-rated dust- and moisture-resistant housing make it ideal for harsh work conditions. The IP33 protection rating means the device is shielded from access to hazardous parts with a wire and from solid foreign objects with a diameter of 2.5 mm or larger. Additionally, it is protected against water spray at an angle up to 60 degrees from the vertical.

Advanced Welding Technology Backed by the Longest Warranty

Paton welders are engineered to deliver exceptional performance and reliability, making them the perfect choice for any welding project. The unique design of the device provides effective cooling, maintaining high performance even in dusty production environments.

Our products stand out with a stabilization system that handles large, long-term voltage drops in the supply network, ranging from 160V to 260V. This ensures stable and reliable operation under varying conditions. All Paton welders are manufactured in our state-of-the-art facility in Kyiv, where we maintain strict quality control throughout the entire production process.

Every Paton welder undergoes a full cycle of rigorous testing to ensure it meets the highest standards of quality and reliability. Our commitment to excellence is backed by up to a 5-year warranty, one of the longest in the industry.
