Welding inverter MMA from the manufacturer Emtop, 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 has an output current of up to 160A. which requires more time to melt thicker wires and more passes on thicker welds..
