Quick Verdict
When you're choosing welding soldering equipment, these two FEIFANKE MIG welders answer different questions. The 135A Flux Core MIG Welder is the compact pick for gasless flux core jobs, Lift TIG, and Stick welding around the home, garage, auto, and farm. The 250A Aluminum MIG Welder is the higher-output workshop machine for gas MIG, gasless MIG, Stick, and Lift TIG, with aluminum as a headline capability.
Price and Capability at a Glance
Here is how the two compare at their listed prices.
| Model | Listed Price | Processes | Weight |
|---|---|---|---|
| FEIFANKE 135A Flux Core MIG Welder | USD 99.99 | Gasless flux core, Lift TIG, Stick | 13.51 pounds |
| FEIFANKE 250A Aluminum MIG Welder | USD 238.99 | Gas MIG, gasless MIG, Stick, Lift TIG | 33.8 pounds |
Where the 135A Wins
The 135A is easier to live with if you want to weld without managing gas bottles. It runs gasless flux core wire, which keeps setup simple, and its low weight makes it easy to move between workbench and vehicle. The semi-automatic feed is helpful when you are still learning how wire speed feels, and the process set covers Flux Core, Lift TIG, and Stick. At its listed price, it is the lower-cost entry point into a multi-process machine. The 30% duty cycle means you will want to pause and let it cool during heavier sessions.
Where the 250A Wins
The 250A becomes the clear choice when your projects move beyond light repairs. The title says aluminum MIG, and the listing supports gas and gasless MIG, Stick, Lift TIG, plus solid, flux core, and aluminum wire. The 250A output, dual 110V/220V input, and MB15 ergonomic torch are aimed at more demanding workshop work. It is heavier, so plan on a cart or bench, but the large LED display and manual adjustment give you more room to fine-tune a weld.
Product Notes
FEIFANKE 135A Flux Core MIG Welder
This is the pick if your welding happens in short bursts and tight spaces. At USD 99.99, it is the lower-priced way into flux core MIG welding, and the gasless operation removes bottle and regulator setup. The 30% duty cycle is a reminder that it is built for lighter sessions rather than continuous production. Its 13.51-pound weight and portable design make it easy to lift onto a workbench or carry to a repair. The semi-automatic feed keeps wire feeding simple, and the lower price leaves room for wire and accessories. Pair it with Lift TIG or Stick for tasks those processes handle.
FEIFANKE 250A Aluminum MIG Welder
At USD 238.99, the 250A is the higher-priced machine, and it earns that position with output and process flexibility. Its 250A rating, dual 110V/220V input, and aluminum MIG focus make it a stronger candidate for a workshop that handles mixed metals. The listing supports gas and gasless MIG, Stick, and Lift TIG, and it can run solid, flux core, and aluminum wire. The 33.8-pound weight makes it more of a stationary or cart setup, and the ergonomic MB15 torch is meant for comfortable extended use. The manual adjustment lets you fine-tune settings, and the large LED display keeps them readable. It is not a grab-and-go portable in the same way as the 135A; you need space and a stable surface for this one.
Final Choice by Use Case
For home garage or farm repairs, occasional DIY, and a tighter budget, the FEIFANKE 135A is the practical choice. For aluminum fabrication, gas MIG, and higher-output workshop work, the FEIFANKE 250A earns the extra spend. If gasless simplicity and easy handling matter most, go with the 135A. If aluminum is on your project list and you have room for a bigger machine, the 250A is the one to buy.
