Review: estaba un poco nervioso por los comentarios negativos. Pero todo bien. Estoy contento - todo sirve muy bien.
Review: I'm very impressed with the utility of this welder. Although I haven't welded in over 40 years, I still remember all the necessary fundamentals. I started using this welder recently and within a few minutes I was able to get it adjusted for 12ga mild sheet steel. I then used it to repair several broken brackets on my John Deere L110 mower deck. This was on a dedicated 120V 20A circuit with the welder set to 100A 19.0V and using the supplied .040 flux core wire. Never tripped the breaker even with welds several inches in length. All the welds looked good with good penetration. So, should I pay $700 for a new mower deck or $150 for a capable welder? That's a "no brainer". The Bestarc plasma cutters are highly rated and it seems the welders are very high quality too.

## Features

- Harmful if swallowed.
- Synergic Control: bestarc mig welder adopt IGBT Inverter and Synergic technology to automatically match the recommended voltage and wire feed speed (current). At the same time, users can also adjust the welding current,you can fine tune the voltage between -3V~3V. Ideal for both beginners and seasoned professionals.
- 4-IN-1 welder: 145Amp mig welder, MIG145 has multi-function for solid/Gasless MIG, Lift TIG and Stick. Maximum current is 145 Amp, supporting the welding of gasless flux-cored mig wire(E71T-GS) and solid mig wire(ER70S-6), and can use 0.030"/0.035"/0.040" flux core wire size, 0.030" solid wire size. The MIG welder excels in welding stainless steel, carbon steel, and even thicker steel, meeting diverse welding needs.
- 110/220V Dual-Voltage: The MIG welder supports 110/220V dual voltage, automatically identifying the input voltage, and clearly display through the front panel indicator. This design enables the welder to work seamlessly in different power environments, providing greater convenience and applicability.
- Solid/Flux Core MIG Welder: The MIG welding machine supports both solid MIG welding and gasless flux core welding. When welding stainless or carbon steel, run the solid MIG mode with solid wire for clean, precise results. When working outdoors or in a windy environment, run the gasless flux-core MIG mode for stable, reliable welding performance anywhere. This MIG welder provides greater flexibility for different projects and working conditions.

Update 3 - Purchased the 165 to check it out and bestarc fixed all of my serious complaints about the early 145. See update #3 at the bottom. And I'm changing from 4 to 5 stars now. I purchased this 145 only to review it. I have plenty of welders from Amazon and that something freight store, some good some bad. I also own a decent mid-range quality non amazon MIG / Stick welder set up for flux also. I have a background in production MIG and also stick weld 7018 for critical welds. So here are my first impressions and I will update as I continue to use this machine. The good- it's a Bestarc, from the company that has the absolute best affordable plasma cutters on the market, for a price you can leave out in a garage and not worry about if it gets stolen. Fan is actually intermittent, which is something Pete's tools on YT is a big fan of (thanks Pete for steering me to Bestarc plasma cutters) but I don't really care about noise. The ground clamp is pretty good (does not need to be changed out immediately like the something freight store green one does), and the cable is labeled 16 square millimeters (copper clad aluminum) , whereas that something freight store 125 is only labeled 10 Square millimeters (but they kind of look the same size). Oddly enough the ground clamp is actually longer on the Bestarc. The bottom line on weld quality is, yeah I think I've got a better looking weld with the Bestarc (on 120v) than the later model of that something freight titanium 125amp welder. So I think it will actually weld better along with having a 220 volt capability, and reverse polarity capability to try to run some stainless flux core wire. Last little thing, the latches and the handle on top of the machine is what I wish that something freight store flux 125 had. The bad- I cannot understand why Bestarc would choose to make the gun only be a five and a half foot lead. I got by with it on scrap coupons, but I think it's going to be an issue for real world welding. The something freight store titanium 125 has a 7 ft leadwhich is just enough in my opinion. If the best Arc is set on the floor, the gun just is not long enough to reach your work at all angles. This 5 and 1/2 ft cord might be okay if you are slinging the machine over your shoulder all of the time, but that's rare in most circumstances - so come on Bestarc let's add a half meter to the gun cable. Then there's the drive roll issue which there are only "v-groove" drive rolls supplied with the machine. The something freight 125 has a "knurled v-groove" which is pretty much standard for flux core wire, though it does have a tendency to wear your gun liner more. And honestly on my first use, the Bestarc straight v-groove fed my .030 wire no problem. I'm not impressed with the spool holder as spring tension is not adjustable. The gun has a bit more of an angle than the something freight store flux 125, which is nice. But the Bestarc has a push on mig nozzle I'd like to change out to a flux core nozzle, and I don't know where to get that kind of nozzle (I may try to drill one of my threaded ones). And for my final complaint, there is nothing in the manual that talks about what the rotary switch does when you push it in. The wire I'm mostly running is kind of an oddball multi pass that really likes a short stick out in order to get hot and run right (E71T-11). I had to kind of pick and prod at the display to finally figure out that I needed to push in the rotary knob, then turn it to adjust the ratio so it makes a different wire feed speed versus the voltage. E71T-GS (from that something freight store) ran good at the normal pre sets. In all honesty I'd like to have dials and no digital display as a flux core machine, but still have the capability to reverse the polarity. Yes stick capability is really nice, but I have another cheap machine for that. Then again given its capabilities of TIG MIG and SMAW, I guess it's kind of got to be electronic for all those modes on one machine. Over all, it's a 5 star machine from a 5 star brand. It gets 4 stars because it needs: 1. A half meter longer gun lead 2. A knurled drive roll for .030 and .035 flux wire 3. A few lines in the manual that state by pushing in the rotary knob, you can access the adjustment for manual wire feed speed vs voltage when doing flux core multi pass vs single pass wires 4. Get rid of the included "free" spools of wire. Update 1 - push on flux core nozzles are available at that something freight store Update 2 - DEFINETLY NEEDS a knurled drive roll for flux core wire. I swapped one from my "something freight store" flux 125 and it made a huge improvement on arc stability because it made the feed speed constant. I am going to try to re-engineer the wire spool tensioner so that I can adjust to a lower tension also, and that may allow the use of the non knurled V-groove drive roll again. Update 3 - looks like the latest 145's now come with the same up grades as my new 165 and I'm stoked. My new 165 came with 2 knurled drive rolls with one having a groove for .035 - now my most used size Longer torch lead - long enough to make it work in all situations, but not excessive to where it would be a liability when you are shouldering the machine But it still needs some improvement in the manual to tell you that pushing in the adjustment knob will allow you to adjust the presets + or -. Still comes with wire I dont need. The spool tensioning system seems to be too tight, so I just made a lighter tension spring out of some galvanized electric fence wire. Works great now. Does not come with a v groove drive roll,which isnt a big deal, since MIG can still get by using a knurled drive roll. But flux core works best with the newly included knurled drive roll. And I think the max amperage for stick welding is only 130amps??? Kind of weird, but I have 2 other machines dedicated to stick welding anyway (one is a bestarc). So when reading through my review, please understand that I origionally purchased one of the early 145's, and now my rating reflects the later 145 and 165 model.
