Inverter welding MMA / MIG from the manufacturer Helix, where the inverter technology enhances the performance and durability of the machine and helps reduce its weight. The MMA electrode method creates thick and strong welds without the need for an external gas supply, making it ideal for welding outside the workshop. 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. It can operate continuously for 6 minutes at 180A before needing to stop to cool down.
