How to choose the right one
-
Match welding process
Decide if you need MIG or TIG for aluminum. MIG is faster and easier for hobbyists, while TIG offers precision for thin metals. The AZZUNO 155A uses MIG for light tasks. The 200A AC/DC Pulse TIG Welder suits fabricators needing precise pulse control. Choose MIG for speed and TIG for quality on delicate joints. Your typical project determines the right process.
-
Check amperage needs
Amperage dictates how thick your aluminum can be. Higher numbers handle thicker materials. The 250A unit delivers power for heavy tasks. The 155A model suits light work. Check the listed amperage against your typical gauge. Select the process that matches your thickness needs. A 200A machine offers a middle ground for versatile work. Ensure the spec meets your material requirements.
-
Verify input voltage
Dual-voltage input allows flexibility in power sources. This feature is key for portability or varying workshop setups. The AZZUNO 155A and 250A both support dual voltage. This lets you weld in different locations without changing power adapters. Check if your workspace supports the required voltage. Dual voltage adds convenience for hobbyists moving equipment. It ensures the machine works where you need it.
-
Consider weight and size
Portability matters if you move your welder often. The 155A weighs only 12 pounds and measures 13 inches long. The 200A Multiprocess MIG Welder weighs 30 pounds. Heavier units offer more power but less mobility. Check the weight and dimensions in the specs. Lighter models suit hobbyists who value ease of transport. Heavier ones fit stationary shop use. Compare size against your storage and transport needs.
-
Evaluate extra features
Additional features like pulse or plasma cutting expand capabilities. The 200A 9-in-1 model includes a plasma cutter. This replaces two tools for shops with space limits. Pulse control helps manage heat on aluminum. The 200A AC/DC Pulse TIG Welder offers this precision. Check if you need cutting or advanced welding modes. These features add value for specific fabricator needs. Match features to your actual workflow requirements.
-
Assess current type
AC/DC current type is vital for aluminum TIG welding. Aluminum requires AC to clean oxides. The 200A AC/DC Aluminum TIG Welder provides this control. It fits welders needing professional-grade waveform settings. DC is less useful for aluminum alone. Check the current type in the attributes. AC is essential for clean aluminum welds. Ensure the machine supports the right current for your material.
