    This welding machine is truly excellent! The 4-cylinder engine provides ample power, it doesn't overheat during continuous operation, the dual-drive wire feeding is incredibly stable, and the welds are smooth. The built-in generator is super convenient for outdoor work, and the 100L fuel tank provides impressive endurance, significantly improving construction efficiency.
