Two MIG welders sit at very different points on the welding soldering equipment scale: one is a light, compact machine, the other is a heavy multi-process unit. The decision comes down to whether portability or process range matters more for your projects.
Quick verdict
At USD 117.82, the AZZUNO 135A is the lighter, lower-priced pick for basic steel jobs. At USD 238.99, the FEIFANKE 250A is the more capable multi-process machine. The $121.17 spread between them is the real decision shortcut: if you only need basic MIG work on thin steel, the AZZUNO keeps more money in your pocket; if a wider process range is coming, the FEIFANKE earns its higher position.

Product notes
AZZUNO 135A MIG Welder
The AZZUNO 135A is a compact MIG welder that keeps the controls approachable. It is aimed at mild steel up to about 3.0mm, and the Lift TIG torch is not included. What it lacks there it makes up for in the box: a MIG gun, electrode holder, earth clamp, and flux-cored wire are included, so the essentials are covered for a first project. The small footprint helps in a crowded workspace, and the straightforward setup is a lot to like for small repairs and thin steel. If your jobs stay in that range, this machine keeps the decision simple.
FEIFANKE 250A Aluminum MIG Welder
The FEIFANKE 250A is a multi-process MIG welder built around a comfortable MB15 torch and a large LED display with manual adjustment. That combination is welcome when you're dialing in a new wire setup or running a longer session. It accepts solid, flux-core, and aluminum wire, and the 5kg spool compatibility suits workshop-scale work. The trade-off is that it needs a dedicated storage spot rather than being thrown into a car. Multi-process jobs and mixed-metal work are where it earns its keep, because you can switch materials and methods without changing machines.
Final choice by use case
Pick the AZZUNO 135A if you need a portable, easy-to-move MIG for steel repairs and you're comfortable with the included setup. Pick the FEIFANKE 250A if you need gas or gasless MIG and multi-metal capability in a workshop setting. If you're still split, ask what the next job actually is: a quick steel repair points to the AZZUNO; a mixed-metal project points to the FEIFANKE.
