AZZUNO vs LOTOS Welder Specs
Welding processes
The AZZUNO unit is a 5-in-1 machine supporting Flux Core MIG, Gas MIG, Aluminum MIG, Stick, and Lift TIG. You get five distinct welding modes in one device. The LOTOS LT5000D is a dedicated plasma cutter. It does not weld; it cuts metal. If you need to join steel, aluminum, or stainless steel, the AZZUNO offers the necessary processes. The LOTOS is strictly for severing metal. This is a fundamental difference in capability. The AZZUNO provides versatility for fabrication. The LOTOS provides precision for cutting tasks. You must choose based on whether you need to weld or cut. The AZZUNO wins for general joining needs.
Amperage output
The AZZUNO is rated at 155A. This amperage supports MIG and Stick welding on various thicknesses. The LOTOS LT5000D outputs 10-50A DC. Plasma cutters use amperage differently than welders. Higher plasma amperage allows for thicker severance cuts. The LOTOS achieves a 3/4-inch severance cut at 50A on 220V. The AZZUNO’s 155A is for arc stability and deposition rate during welding. You cannot directly compare these numbers as one is for joining and the other for cutting. However, the AZZUNO offers higher numerical amperage for its welding processes. The LOTOS offers sufficient amperage for its specific cutting duties. Both are adequate for their respective functions.
Cutting thickness
The LOTOS LT5000D excels at cutting. It provides a 5/8-inch clean cut and a 3/4-inch severance cut on 220V power. It can also cut 1/3-inch clean and 2/5-inch severance on 110V. The AZZUNO does not cut metal. It joins metal. You cannot use the AZZUNO for any cutting task. If your primary goal is to slice through steel, aluminum, or copper, the LOTOS is the only option. The AZZUNO is irrelevant for this metric. The LOTOS handles thick plate severance effectively. The AZZUNO cannot handle any thickness for cutting. The LOTOS has a clear advantage for material removal.
Portability and weight
The AZZUNO weighs 12 pounds. Its dimensions are 13 inches long, 8.5 inches high, and 5.7 inches wide. It is compact and lightweight. You can easily move it around a workshop. The LOTOS LT5000D weighs 22.5 pounds. Its dimensions are 10 inches long, 26 inches high, and 13 inches wide. It is significantly heavier and taller. The LOTOS includes a handle for portability, but the mass makes it less mobile. The AZZUNO is easier to carry and store. For jobsites where you move equipment frequently, the lighter AZZUNO is more convenient. The LOTOS is better suited for a stationary workshop setup.
Material compatibility
The AZZUNO welds aluminum, steel, and stainless steel via MIG, Flux Core, and Stick processes. It supports .030-inch to .045-inch wire for aluminum and steel. The LOTOS cuts stainless steel, alloy steel, mild steel, copper, and aluminum using compressed air. Both handle aluminum and steel. The AZZUNO joins these materials. The LOTOS separates them. The AZZUNO also works with E6013 electrodes for Stick welding. The LOTOS does not weld. If you work with non-ferrous metals like copper, the LOTOS cuts it easily. The AZZUNO welds it if you have the right wire. Both are versatile, but for different actions. The AZZUNO offers more joining options.
Which Welder Fits Your Metalwork Needs
