FEMEROL 250A MIG Welder,6 in 1 Gas MIG/Gasless Flux Core/Stick/Lift TIG/Spot Welding/Spool Gun Compatible Aluminum Welding Machine Large LED Display 110V/220V Multi Process Welder

My background; Fairly experienced welder in most processes like MIG, Flux Core, MMA, TIG. But retired now so want to "play" with fabrication/prototype design stuff, and wanted a nice portable welder that had 110/220 Volt options but not pay $4000+, as I did with my Miller Multi-Process. I still have this welder and is excellent but I wanted a more portable unit. OK, so what I looked for in a welder is more amps output than I need, easy user interface for the varied processes, lightweight, spool gun-compatible, spot weld option, 110/220V inputs, Auto-Set for amps/wire speed, adequate torch, stick, ground cable lengths, and price. Postitives: Femerol has 250A at a 60% duty cycle, which is excellent, and has 250A/60% on all processes (MIG, MMA, TIG). Figure about 1 Amp required per .001" thick steel stock, so 1/4" plate steel (.250") needs about 250 amps for MIG process, or ~40A/mm. Note: Flux Core or stick will allow a thicker steel to be welded. So for thicker steels using MIG, 250+ amps is needed, and this machine does in theory offer that. I checked the output, and using a shorting bar (not simply weld, as the impedance losses alter true amps output), it would put out ~ 230A, and if it had a heavier duty outlet/plug, it would get close to 250 Amps. I did change out the plug/cord to #10 gauge with a 50 Amp plug, as all welders of this ampacity should have, and it did put out ~245Amps for a short time. User interface: The machine is intuitive to most weldors with experience but the novice users should be able to follow the decent manual (BTW, "weldor" is the person, "welder" is the welding machine). Several good youtube channels, including weld.com, weldingtipsand tricks, are great learning resources. If you buy this welder (or any other brand), note polarity is reversed for Flux Core, vs MIG. Weld features, and weld quality: This machine has almost every feature one would need to weld, except Pulse MIG, and AC/DC TIG, which would add a huge increase to the cost, so this welder works for 99% of my welding needs. This machine can weld aluminum, via the included teflon liner for the MIG torch, or the Spool Gun option (Spool Gun not included but can be purchased for ~$80-95). Some of the features I like are the spot-weld option, multiple sizes of MIG wire compatibility, and the stability of the arc, to name a few. I've welded steel from .024", up to 1/2", the 1/2" using multiple passes. It also welds aluminum quite well, even using the MIG torch with the included teflon liner. Using Lincoln 5356, .035" Al wire, I didn't get any "birdnesting" during the welding. If I did, the drive roller tension can be adjusted to prevent birdnesting. The stick welding is smooth and steady, allowing even thinner materials to be welded, compared to 60Hz AC or DC machines. I haven't used the TIG option, since I already have a high frequency AC/DC TIG machine. The spot function is really handy for welding thinner materials without the need for manually pulling the trigger just the right amount of time. I simply set it to Spot Weld, the menu allows for wire feed (or synergistic auto set), Amps, and weld time adjustments. With this feature, it was easy to consistently weld 24 gauge (.024") without burning through (using .030" ER-70-S6 solid wire). MIG, Stick, Ground cable lengths. All three are ~3meters=9.5' long, which is generous for a welder in this price point. The plug cord, with the 110v-220v adapter measures ~7' on my machine. A design improvement would be to change out the barbed hose connection to a threaded gas fitting, to allow faster hose removal if needed. One can use a short pigtail from the barbed end to a gas fitting adapter, if a faster hose change/removal is needed. So to summarize the positives: Great price, good Amp output, reasonable lengths MIG torch, ground clamp, stick welding, many welding process options, including spot weld, easy to understand controls, Al welding options, spool gun compatible, lightweight. Negatives: Cooling fan kinda loud and runs all the time, 120V plug that should be a 50A, slightly undersized cord, barbed gas outlet. Would I buy it again? Yes yes yes. As a matter of fact, I DID buy a second one during Amazon Prime! Why a second identical welder? I'm lazy. I have one welder set up for MIG, and the other one for Aluminum so I don't have to change liners, spools, and gas (75/25% Argon/CO2 for steel, 100% Argon for Aluminum). My Miller is now set up with the spool gun for Stainless Steel). It's too early to know how long it will last without any problems but I think that for the home shop or light duty fabrication/prototyping shop, it will be a great addition to the shop. UPDATE 11-24. I kept wondering if this welder would die if doing long, high amp mig welds. I just finished a major project where I went through a 10 lb .035" spool in a day, which for me is a lot. I was welding thick (1/4-1/2") long beads and the machine never stumbled. I was going with max amps (250), running multiple passes, and the machine worked great! So for me, and my machine, it passed all the durability tests I gave it. If I had a professional shop, and didn't need to have more than 250 amps, I would use it and my thinking is, "I can buy one name brand for $3000-4000, or buy three, heck, 5 welders, all set up with gas quick connects, and different mig wire for separate operations. And if one died, I have 4 more to fall back on. My thoughts on a general shop: .023" for thin projects, .035" for most/all others, Stainless, Aluminum, hardfacing mig wire, flux core, and a "throw in the work truck for field work (flux core with some MMA sticks. Still happy with it.

So far this welder is doing great, the only picture I got was with dirty painted metal and a weak ground and just a flux core weld, it’s been years since I’ve welded but I’m pretty happy with the results so far. Everyone tried the welder and put out good welds. Super easy welder even for a dummy. I’d take it over my old Lincoln 140 any day so far from what I’ve seen! I’ve seen great reviews so hopefully it lasts me years like my lincoln.

I'm no professional welder, but I really love this machine. So far I've only been running flux core 0.030 wire, I originally purchased this machine to switch to a gas capable machine. But the spatter has been so minimal, I may just continue using primarily flux core wire. Being a multi-process machine is great to have options and the ability to run a spool gun for aluminum, or swap out the mig liner if you want. Even though I'm not an experienced welder the machine's interface is straight forward and easy to use. Though as others say the owners manual is lacking and no welding chart included (but the seller will send you one if you message them). The only real issue I ran into was during setting up and feeding the wire. The contact tips that came with the machine label 0.8mm (0.030") have a manufacturing defect. The tolerance is off on the hole the wire passes through, it was too tight and caused the wire to bind and birds nest back at the roller. Once I swapped the contact tip from my old Harbor Frieght welding machine and adjusted the wire tension, the machine functioned flawlessly. It is nice to know the consumables for this mig gun are compatible with Harbor Freight Vulcan mig accessories. I also put a Vulcan flux core nozzle tip on the mig gun to proctect the gas ports, till I get a bottle of gas. Not nessary, but I had them laying around. Overall a really great machine and I'm very pleased with the purchase. I took 1 star off for the poor quality of the included contact tips and the poor owners manual. But if you are on the fence about this welder, go for it! It's a great machine especially for the price.

The machine arrived on time, in perfect condition. The thing that struck me first off was the build quality, and the weight of the machine. Then just the ascetics of it, for a welding machine it is very easy on the eyes and looks like it is ready to get to work. It looks and feels like a quality machine. I have never been able to run a proper weld with flux core wire, but after setting up the Femerol Mig 250 Pro I was running some quality welds, minutes after un-boxing the unit. Which I am sure will only get better. The display and inputs take a lot of the guess work out of Flux Core Mig Welding. The Synergic Mig function seems to work as advertised. And the ability to fine tune amperage and wire feed rate only help to make quality welds. As a weekend welder, I don't believe you can get a better machine at this price. Update: My welds are getting better all of the time, I am building a cart for the unit to get some practice in. I have the issue of the display blinking after shutting down. I contacted customer support, Lily responded within an hour or so. It seems this phenomenon is normal due to capacitor discharge and such, I was assured it was normal and not an issue. Whew! Because I really like this machine, I believe I'm looking at years of trouble-free service ahead. I'll keep you posted.

At this price point, this welder has many features. some of which are not available on more expensive welders. Such as, spool gun option, spot weld with adjustable time. all 3 cables are approximately 10 feet long and Adjustable inductance. And 60% duty cycle. + and - adjustment in synergic mode for both voltage and Current.it has no limitation on amperage when selecting wire size. on some welders like Arccaptain, if you select 0.030, you can only increase the amperage to 130 Amp max. NOTE: 1: These units must have hefty filter capacitors so when the unit is turned off and caps discharge, the screen flashes for a second of two. DO NOT be concerned. this is normal. I've seen this in other more expensive brand name welder. 2: According to specs, it has a fan on demand. but This has been upgraded to continuous in order to improve the duty cycle. I measured the noise level right next to machine with cover closed and it's lower than average for all these types of welders. 3- Some units may have mig contact tips labeled 0.8mm however it's incorrect hole size it will cause flux core wire to jam. try pushing the wire through it as a test before screwing it on to avoid birds nest. These days, practically 98% of the welders can lay a reasonably nice beads. and this machine makes even flux core look good. The most important feature of any welder, no matter what price range is the actual output current compared to the ADVIRTISED specification. I tested the output current for Flux core synergic (which uses none threaded nozzle) on 220V at different Amp settings. The results Did Not disappoint and exceeded expectations. you can see the full test results for Synergic flux core on YT video under " FEMEROL MIG 250 welder output current Flux core tests" title. WV591 channel. Exceptional customer service !!! Excellent performance. Two year warranty . Great value. It's a Keeper .

I bought this welder not knowing what to expect, but it's a really great unit! The Pulse mode really helps me out making my welds a whole lot cleaner! Full disclosure, I'm a beginner welder, I'm still learning and I'm only learning to have a new skill under my belt for personal projects and home repairs (E.g., decorative Iron RV side gate repair, etc.), but my friend who's been welding for Chevron for over 40 years was genuinely impressed, and blown away at how good this unit was, especially with what I paid for it. He came over to help me weld some anchor points onto my utility trailer, so he got to try it out, and was shocked with its performance, saying it was extremely consistent and powerful, which made me feel a lot better, considering he's a professional veteran welder. I 100% recommend this welder to anyone looking for a smoking deal on a high quality and performance welder, whether your a beginner like me, or a pro like my friend, who wants a small unit for quick, medium duty, non-industrial jobs/projects. Very satisfied.

OH MY GOSH !! I am a professional welder fabricator and i bought this on a whim when my 3000 dollar machine broke down and i had to finish a project . I was wayyyy skeptical cause of the price but this thing literally blew my mind !!!!! It’s sooo much better than my 3000 dollar machine and i can’t even believe it !! I’m stunned at how good it performs!! If i had to say one thing i would tell you to buy this welder if you are thinking about more expensive ones . It blows them ALLLLL away ! I’ve had them all and this one this cheap but very fine machine is far superior!! I’m so glad my machine broke down! I’m not paid to leave this review I’m a real fabricator and a happy one at that !!

Got this Mig Welder and started to hook it up. I will only be using it for Mig Welding. First problem was it comes with a 5/16" Barb for the gas line although the manual shows and describes a threaded connection. I emailed the seller as well as emailed support from the manufacturer listed in the manual to ask about changing the barb to a threaded fitting. I did not want to void the warranty. After more than a week no one responded. This could be a major issue for anyone with a warranty issue and should be noted before purchase. Almost all Tank Gauges come with a threaded connection and a 1/4" Hose barb adaptor. It might not be as easy as you think to find a 5/16" hose barb adaptor. I could not find any with quick shipping and most were at least $10 or more plus shipping. So I took one of my gas hoses with threads at each end and cut it in half knowing the internal diameter was 5/16". Once the hose was secure and checked for leaks I installed a roll of 0.23 solid wire. And here is the next problem. They advertise this unit for using 0.23 wire but they neglect to tell you they do not supply the correct .6mm V roller wheel needed to feed .023 solid wire nor do they supply the 0.23 tip. They only give you rollers and tips for 0.30 and 0.35 solid and flux as well as a roller for Aluminum. Again you would think it is easy to find the correct .6mm roller. After numerous searches and reading reviews, despite the roller being listed as .6mm people received the wrong size. I finally found a listing with good reviews and ordered it. I am still waiting for delivery. So, in the mean time I put in some .30 solid wire with the .8mm roller. I tested the unit on the automatic settings and found it incredibly easy to use and I found the quality of the welds very good to excellent. This welder is a great value for the price even with having to buy another roller and tips. I am on the fence about recommending this welder because I have read other reviews stating the welder died after a loud pop. That combined with both the seller and manufacturer not responding to emails leaves me feeling uneasy.. I will update my review as things progress.
