Welding inverter MMA / MIG / TIG from the manufacturer Ruris, 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). While the TIG method is suitable for slow welding on aluminum and stainless steel, which requires detailed work and does not create splashes. It can operate for 6 minutes continuously at 120A before it needs to stop to cool down. Therefore, you may need more time to melt thicker wires and make more passes on thicker welds due to its low maximum Amps. Its weight reaches 7kg.
