Welding inverter MMA 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. It can operate for 0.7 minutes continuously at 130A 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 5.2kg.
