Aluminum alloy welding requires extremely high arc stability. The OTC DAIHEN P500L welding machine excels in the MIG short-circuit welding mode thanks to its optimized aluminum welding control technology. Below are the recommended process parameters for square butt joints and horizontal fillet welds, provided for the reference of on-site technicians.
