Welding inverter MMA / MIG / TIG from the manufacturer Telwin, where the inverter technology enhances the performance and durability of the machine and contributes to its weight reduction. The MMA electrode method creates thick and strong welds without the need for external gas supply, making it ideal for welding outside the laboratory. The MIG method requires the wire to have a special coating (flux) otherwise it needs to be connected to an external gas cylinder (e.g. argon, CO2). The MAG method creates welds with gas supply, making it ideal for indoor welding. While the TIG method is suitable for slow welding on aluminum and stainless steel, which requires detailed work and does not create splashes. It has an output current of up to 200A. which melts thicker wires more easily and creates thicker welds with fewer passes.. Its weight reaches 13kg.
