Specs: YESWELDER vs AZZUNO
Amperage Output
The YESWELDER MIG-205DS PRO delivers a maximum amperage of 205A, while the AZZUNO Aluminum MIG Welder tops out at 155A. This 50-amp difference matters when you tackle thicker steel or stainless steel plates. Higher amperage allows for deeper penetration and faster deposition rates on heavy gauge materials. The YESWELDER’s 200A robust output is better suited for construction, automotive repair, and fabrication tasks involving thick metal. The AZZUNO’s 155A is sufficient for lighter DIY work and thin sheet metal. If you frequently weld material thicker than quarter-inch steel, the YESWELDER provides the necessary power reserve. For light gauge aluminum or thin steel, the AZZUNO is adequate.
Welding Processes
Both machines offer five welding modes, but their specific capabilities differ slightly in description. The YESWELDER explicitly lists Gas MIG, Flux Core MIG, Spool Gun MIG, Lift TIG, and Stick welding. It notes that a spool gun and additional lift TIG torch are required for those specific modes. The AZZUNO also supports Flux Core MIG, Gas MIG, Aluminum MIG, Stick, and Lift TIG. It highlights SYN, 2T, and 4T MIG modes for flexible control. The YESWELDER emphasizes its ability to handle aluminum via a spool gun setup, while the AZZUNO integrates aluminum wire compatibility directly into its standard wire feed system, supporting .035" and .040" aluminum wire in manual mode. Both cover the essentials, but the YESWELDER’s explicit spool gun mention offers a clear path for aluminum welding.
Wire Compatibility
The AZZUNO provides detailed wire compatibility information, supporting up to 2 lbs of wire spools. It works with .030" and .035" flux core, .030" solid wire, and .035" and .040" aluminum wire. In manual mode, it even handles .045" aluminum wire. The YESWELDER lists a wire feeding speed range from 58 in/min to 858 in/min but does not specify maximum spool weight or specific wire diameters in the provided data. The AZZUNO’s explicit support for .045" aluminum in manual mode gives you more flexibility for thicker aluminum joints without needing a spool gun. The YESWELDER’s adjustable voltage tuning range of -3V to 3V allows fine-tuning, but the lack of specific wire diameter data makes direct comparison difficult. The AZZUNO wins on clarity for aluminum users.
Physical Dimensions
The YESWELDER MIG-205DS PRO measures 20 x 16 x 14 inches, making it a significantly larger unit. The AZZUNO Aluminum MIG Welder is much more compact at 13 x 5.7 x 8.5 inches. The size difference is substantial, affecting where you can store the machine or how easily you can move it between job sites. The AZZUNO’s smaller footprint is advantageous for tight workspaces or portable setups. The YESWELDER’s larger chassis may offer better heat dissipation due to its size, but it requires more storage space. If portability and space-saving are priorities, the AZZUNO is the clear choice. The YESWELDER is better if you have a dedicated workshop with ample room.
Included Accessories
The AZZUNO package includes a comprehensive set of accessories: a MIG torch, electrode holder, ground clamp, gas hose, hose clamps, contact tips for .030", .035", and .045" wires, a nozzle, V-groove and U-groove drive rollers, and a brush and hammer. It also includes 1 lb of .045" aluminum wire and 1 lb of .030" flux-cored wire. The YESWELDER data does not list specific included accessories, only mentioning that additional equipment is required for certain modes. The AZZUNO provides everything needed to start welding immediately, including multiple wire types and sizes. This makes the AZZUNO more ready-to-use out of the box. You save time and potential extra purchases with the AZZUNO’s complete kit.
Which welder fits your needs
Fabricators needing thick steel output
The YESWELDER provides 205A of amperage, significantly higher than the AZZUNO's 155A. This extra power helps you penetrate thicker steel and stainless steel plates more effectively. The digital display lets you monitor real-time current for precise control. It also includes protections against over-current and overheating, ensuring stable performance during heavy-duty tasks.
Beginners wanting a complete setup
The AZZUNO package includes essential accessories like a MIG torch, ground clamp, and both aluminum and flux-cored wire. You get contact tips and drive rollers for different wire sizes right out of the box. The simple interface with two buttons and two knobs makes setup quick. Synergic mode auto-adjusts voltage and wire speed for consistent results.
Aluminum welding specialists
The AZZUNO is designed specifically for aluminum compatibility, supporting .030" to .040" aluminum wire. It handles .045" aluminum in manual mode. The package includes .045" aluminum wire and U-groove drive rollers suited for softer metals. This focus on aluminum materials makes it a practical choice for projects involving light gauge aluminum fabrication.
Users preferring compact portability
The AZZUNO weighs only 12 pounds and measures 13 inches in length. This compact form factor makes it easier to transport to job sites or store in tight workshops. In contrast, the YESWELDER is larger and heavier. If you need a lightweight machine that fits easily into a vehicle, the smaller footprint of the AZZUNO is a clear advantage.

The AZZUNO 155A is the better choice for aluminum welding. Its product data explicitly lists aluminum as a compatible material. This machine is designed for hobbyists who need aluminum capability without the bulk of higher-amperage units. While the YESWELDER supports multiple processes, the AZZUNO focuses specifically on mixed-material projects involving aluminum.
Does the YESWELDER support flux core welding?
Yes, the YESWELDER MIG-205DS PRO supports flux core welding. It is a multi-process machine that includes TIG, Stick, MIG, and Flux Core capabilities. This versatility allows you to handle various joint types and materials. The AZZUNO model, by contrast, is listed only as a MIG welder.
How much heavier is the YESWELDER compared to the AZZUNO?
The YESWELDER is significantly heavier and larger. The AZZUNO weighs 12 pounds and measures 13 inches in length. The YESWELDER measures 20 x 16 x 14 inches. While the exact weight of the YESWELDER is not provided, its larger physical footprint suggests it is built for stationary shop use rather than portability.
Can I use a spool gun with the YESWELDER?
Yes, the YESWELDER MIG-205DS PRO includes a spool gun feature. This accessory is essential for feeding soft aluminum wire without birdnesting. The AZZUNO product data does not mention a spool gun, so you would need to verify compatibility separately if you plan to weld aluminum with that specific machine.
What is the maximum amperage for the AZZUNO welder?
The AZZUNO 155A Aluminum MIG Welder has a maximum amperage of 155A. This output is sufficient for light fabrication and thinner materials. It offers a lower power ceiling compared to the YESWELDER, which reaches 205A. Choose the AZZUNO if you prioritize aluminum compatibility over high-amperage penetration for thick steel.
Does the AZZUNO welder support TIG welding?
No, the AZZUNO 155A is listed only as a MIG welder. Its product data does not include TIG, Stick, or Flux Core processes. If you require TIG welding capabilities, you must choose the YESWELDER MIG-205DS PRO, which supports TIG, Stick, MIG, and Flux Core welding in a single unit.
