The Kemppi Master 315 G is a professional MMA welding machine developed for demanding industrial applications, workshops, and on-site installation work. With a maximum welding current of 300 A, the machine delivers high performance, a stable arc, and consistent weld quality when working with all common electrode types, including cellulose electrodes.
The welding machine is equipped with Kemppi’s Weld Assist function, which simplifies setup by automatically adjusting parameters based on electrode type, diameter, and joint type. This reduces the risk of incorrect settings and increases productivity, particularly in applications involving varying welding tasks.
The integrated 7-inch TFT color display provides a clear overview of welding parameters and machine status. Up to 99 memory channels allow storage of recurring settings and WPS data, making the Kemppi Master 315 G an efficient solution for both serial production and service work.
The machine is suitable for operation with generator power supplies and can also be used for DC TIG welding when equipped with an external TIG torch. Its robust construction and IP23S protection class make it suitable for use in demanding environments, both indoors and outdoors.
Kemppi Master 315 G is a reliable choice for professional users seeking a powerful, flexible, and long-term durable MMA welding machine.
