155A vs 175A Spec Breakdown
Amperage Output
The AZZUNO 175A Dual-Voltage Aluminum MIG Welder offers a higher maximum output of 175 amps compared to the 155A model's 155 amps. This additional current capacity allows the 175A unit to handle thicker materials more effectively. While both machines are rated for dual-voltage input, the higher amperage on the 175A version provides greater flexibility for demanding tasks. The 155A model remains sufficient for lighter gauge metals, but the 175A option gives you more power reserve. This difference is significant if you frequently work with materials that require higher heat input for proper fusion.
Wire Spool Capacity
The 175A model features a semi-enclosed design that accommodates wire spools up to 10 pounds. In contrast, the 155A model supports up to 2-pound spools. This is a major practical difference for extended welding sessions. With the 175A unit, you can load larger spools and weld for longer periods without stopping to change wire. The 155A’s smaller capacity may require frequent reloading if you are working on larger projects. For users who prioritize convenience and reduced downtime, the 175A’s ability to hold significantly more wire is a clear advantage.
Display Interface
The AZZUNO 175A Dual-Voltage Aluminum MIG Welder includes a large, clear LED display screen. This oversized interface provides crystal-clear visibility and a clean layout for intuitive operation. The 155A model relies on two buttons and two knobs without a mentioned digital display. The LED screen on the 175A allows for faster and easier adjustment of settings. You can see exact parameters rather than guessing based on knob positions. This feature enhances precision and reduces setup time, making the 175A superior for users who value digital feedback and precise control over their welding parameters.
Portability and Weight
The 155A model is lighter and more compact, weighing 12 pounds with dimensions of 13 x 5.7 x 8.5 inches. The 175A model weighs 14.5 pounds in the data, though another spec lists 20 pounds, with dimensions of 15.7 x 5.7 x 9.0 inches. The 155A is easier to carry and store due to its lower mass and smaller footprint. If you need to move the welder frequently between job sites or have limited storage space, the 155A’s lighter build is preferable. The 175A is slightly bulkier, which may be a drawback for users prioritizing maximum portability.
Wire Compatibility
Both welders support similar wire types, including flux core, solid, and aluminum wires. The 155A explicitly handles .030", .035", and .040" aluminum wire in manual mode. The 175A supports .030", .035", and .040" ER5356 aluminum wire. The 175A comes with a Teflon conduit for aluminum welding, while the 155A includes drive rollers for various wire sizes. Both machines offer five welding processes. The 175A’s inclusion of specific aluminum wire compatibility details suggests optimized performance for that material. However, the 155A’s manual mode flexibility for .040" aluminum is also robust. Both are versatile, but the 175A’s specialized aluminum setup offers a slight edge.
Control Functions
The 175A model includes Spot welding and a manual wire feed button, in addition to SYN, 2T, and 4T modes. The 155A offers SYN, 2T, and 4T modes but does not list Spot or manual wire feed buttons. The Spot function allows for timed welds, useful for specific applications. The manual wire feed button on the 175A helps quickly feed wire without triggering the weld. These additional controls on the 175A provide more operational flexibility. The 155A’s two-button, two-knob system is simpler but lacks these advanced features. For users needing precise control over weld duration and wire feeding, the 175A is the better choice.
Choose the Right AZZUNO Welder for You
Users needing thick wire capacity
The 175A model supports 10 lb wire spools thanks to its semi-enclosed design. This larger capacity reduces downtime for frequent welders. The 155A version only accepts up to 2 lb spools. If you run through wire quickly, the larger spool holder on the 175A is a practical advantage for longer projects.
Users wanting clear digital feedback
The 175A unit features a large, clear LED display for easier setting adjustments. The 155A model uses two buttons and two knobs without a screen. If you prefer visual confirmation of your settings over manual dial adjustments, the digital interface on the 175A provides better visibility and intuitive control during operation.
Users prioritizing lighter portability
The 155A model weighs 12 pounds and measures 5.7 by 8.5 by 13 inches. The 175A version is heavier at 20 pounds and slightly larger. If you need to move the welder often or store it in tight spaces, the lighter weight and compact footprint of the 155A make it easier to handle.
