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

Precio y calidad van de la mano

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.

Haven’t had much of chance to use it yet but can say the product support works as I’m getting help learning the specific features of this unit.

My transformer type MIG welder was getting tired so I purchased this Inverter model. I was not sure where it was made but on the box it said Made in China. I came with all the accessories as described. I just had to change the power plug to a 16 Amp plug, load some wire, connect the CO2 cylinder and start to set it up. In around 10 mins I got it set to weld 1.5mm steel plate, weld is very consistent but I am sure I can adjust even better. What I noticed is that the ground cable and torch are very light so its aluminium, most probably I will hook up my old ones as these are copper and heavy duty. Other than that so far so good. All in all its alot of welding machine for the purchase price.

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.
