Questions & Answers

The welder comes with a gas gauge. Can it use argon?
ByNov 13, 2023

Answer This Question

Yes, the Lotos MIG 140 welder comes with an argon regulator. It can use argon gas for MIG welding. It also comes with a spool of flux core wire so it can be used without gas as well.

    Answer This Question

    Where can I get the 0.035 inch contact tips for this welder, the Lotos Mig140? I don't see them listed on the Home Depot website. The Lincoln Electric 0.035 inch contact tips looks similar, are they compatible with the Lotos Mig140?

    Answer This Question

    The tips .035 are all universal, many welding stores or online. I personally got mine online by bulk, but Harbor Fright, Tractor Supply and our local welding stores.

    By|Mar 29, 2020

      Possibly but not all MIG tips have the same thread size.

        It appears from the photos, that it comes with a spool of wire. Is this wire flux core, or does it require gas?
        ByFeb 27, 2020

        Answer This Question

        Yes it is flux core wire, it works great, I prefer solid wire with gas, clean weld.

          Does this use inverter technology or transformer?

          1 Answer | 
          Answer This Question

          From the weight, I'd say that it is a transformer.

          By|Feb 27, 2020


            is the wire always hot, in another words, if you release the trigger then let the wire touch ground will it spark(try to weld)

              Yes its live till you turn power off.

              By|Mar 15, 2019

                Hi, There is a 4T/2T switch on the front panel If you are using 4/T then once you press the trigger once, the wire feeder will run and there will be heat output on the torch until you press the trigger again to stop. If you are using 2/T then once you release the trigger the wire feeder and the heat will both stop. Thanks for your inquiry Regards Lotos Technology

                      It broke in the first 5 minutes of use
                      I bought this from Home Depot dot com, and had it at my farm, for nearly a month, before completely unboxing it, to use. We needed to repair a 6"x 6' steel I-Beam that is the heart of my log splitter. We weren't even into really dong any welding yet, when the wire feeder stopped working. Fortunately, I called the canufacturer, described the problem, and they agreed to replace it, right away. They shipped me a new one, that day, and I just got it delivered. Time to get back to welding.

                        Good machine, came very well packaged and there was no damage. It took no time to set up and get dialed in. I was welding with it in 30 min. of bringing it home. The trigger is crisp and I like the ball on the wand, it doesn't feel like it gets in a bind.

                        For the money I don’t think you can buy a better machine . I have owned commercial units that didn’t weld any better and cost thousands of dollars. For at home or light industrial use I don’t think you could buy a better welder
