LOTOS MIG140 140A MIG Welder Advanced Auto MIG Synergistic Setting, Voltage Fine Tuning, Gas MIG Welding & Gasless Flux Core MIG Welding - Brown, 120V, Without Aluminum Spool Gun

This is my first welder and now that I'm really into welding, I know that it's not going to be my last. But that doesn't mean it's not a great intro-level MIG welder. It's served me very, very well and never failed me. In fact, through several years of welding with it now, it's never failed me once. Now that I'm more advanced I might want a better regulator and gun and maybe even a 220 powered machine ... but this thing has been great. My video is from a recent roof rack welding project of mine using this welder. I use it inside and outside, and you'll see that i welded up a simple cart for the welder just so I can move it and the tank around. If you're new to MIG you'll need a tank and gas to make this baby work. I got mine at a local welding store. YOu'll also need more wire, as it comes with a very small spool. I found cheap wire at HFreight. Look for other welding accessories and you should be good to go (a mask is essential, you may also want gloves and magnets and the stuff for cleaning/protecting the head of the welder). This welder is entirely plus-and-play, meaning it was easy for me to learn how to use. MIG is a great place to start making solid welds, and I've been very happy with this affordable machine.

Wire that comes with it welds well. Gun is decent. I chose to grind one of the included nozzles down till it was flush with the tip. It welded a little cold before doing that like it had too much stickout. Afterward, the weld profile was much flatter and had better fusion at the toe. I also have switched the nozzle over on the gun so that I hold it like a tig torch. I'm not entirely sure how anyone points the nozzle down on a MIG and still hits the trigger, but everyone seems to do it. I can't though. I need to sit down and prop a pinky on something to weld smoothly. This gun allowed me to do that and use my index finger for the trigger. I really like that. The regulator is good. The machine seems to read accurately. I thought the ground cable was a bit dinky looking, but it doesn't get hot like my TIG machine clamp does at even 60amps. Some reviewers had an issue with the feed mech? Not sure if the company fixed it, but I've had zero problems running the wire that came with the machine. No slipping or birds nesting whatsoever, even with the cable in non-ideal positions.

This is the first, sincere review I've left for a product on amazon. My conscious would not be clear if I didnt. Truly a company that stands by their product. Much past the first year of my ownership of the welder I had a wierd issue arise that would cause the wire to just ball up as it came out of the gun and eventually just fall to the floor. I found that the wire feed mechanism was malfunctioning and the welder in general making a pretty loud racket. I contacted support and after some back and forth of photos and videos describing my problem they sent me both a new circuit board and and new feed motor assembly. This didnt fix the issue so they sent me out a replacement welder and paid postage to send the one I was having issues with back to them. Keep in mind this well past any warranty. This welder works perfectly and while i was initially frustrated at it failing to work reliably I was amazed at their efforts to make it right for me. Even when they had every ground to make me pay for shipping and for repair. All in all. A solid company to deal with that takes responsibility for their products. Would definitely recommend to anyone looking to get a decent welder at this price.

After setting up the welder and making a few short weld passes, I am very impressed overall. Since I have not had a chance to use it on a project yet, I really haven't tested the welder's capabilities. Nor have I tried to make any MIG welds. At this point, I can say the LOTOS welder is superior in almost all respects to the flux core welder it is replacing (which in all fairness is 24 years old). The LOTOS has greater control over welding parameters, the overall construction of the welder is vastly superior, it costs about the same as my original welder, it has MIG capability, and so far, the weld quality is significantly better. I look forward to using the welder on a real welding project and will try to provide an update afterwards.

It worked long enfo to use up the little spool that came with it but after buying a new tank of gas and a new spool of wire theres no power and im out all that money

The mig handle where the nozzle is broken . It would require a new unit. Not impressed

I had ordered this welder once before but when it arrived it wouldn't feed wire so I sent it back And waited. Few months later I seen where the drive system was updated to all aluminum and decided to try again since it was cheaper still than other welders. It arrived in decent time. I did have to purchase flux core wire as it comes with solid but everything worked right out of the box. You can NOT weld with solid wire without shielding gas, it will not weld properly. A few days after I got it, it quit feeding wire. Instead of sending it back I decided to take a look at it see what was wrong. Pulled the handle apart and found a wire had come loose from the trigger switch. Could've been a weak solder, could've been something I done. I soldered it back together and have had no more problems since. It makes good welds for a 110v welder with flux wire. I've welded with forneys and hobarts and high grade Miller's. This unit welds just as good as the hobarts of the same size. If I had to go back I would do it again. It's cheaper than other welders and welds just as good. Edit: 1 year after previous review. Welder is still working flawlessly. I have welded everything from thin exhaust pipe to heavy gauge steel tubing. It welds great every time. Still have not tried it with gas only flux. Seen a review that said they had to pay to return item. I personally went through Amazon with my return and did not cost me anything, and was fully refunded. All and all I still say great welder. Even if I did have some initial trouble, no company I have ever shipped with has been perfect every time. Edit: year is 2021-welder is still working flawlessly. Have had zero problems(besides initial solder issue) since purchase 6 years ago. I have switched to gas and this welder is even better. It welds just as good or better than Lincoln, Forney, or any other in its class. The rubber jacket on my welding lead is starting to crack from age and use but still works fine.

Great welder regardless if you're welding with MIG or Fluxcore! The only downside to this welder is the lack of customer support and interchangeable accessories as seen with Hobart and Miller products. This is to be expected, however, due to the inexpensive price of the unit. She will run a perfect bead at a constant feed rate and is very easy to operate. The only downside is the extremely vague users manual and the lack of customer support. If you want a quality welder at a novice price then this is the unit for you! Don't expect to start a welding business with this, but you can expect to be pleasantly surprised by the performance of this one. I would gladly buy again in a heartbeat (except this is a wonderful machine and I won't need to for a long time!) P.S.-the manual doesn't really mention a whole lot about flux-core wire and that is mainly what I run due to the ability to be used anywhere in any condition. It welds great and as long as you use a little common sense and swap the polarity (which is easy to do with this machine) you will be just fine!
