Pero todo bien. Estoy contento - todo sirve muy bien. ### ⭐⭐⭐⭐⭐ Review *by M***V on 19 February 2024* 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. ## Frequently Bought Together - bestarc 145A MIG Welder, 110V/220V Gasless Flux Core MIG Welder/Lift TIG/Stick 3 in 1 Synergic MIG145 5GEN Welding Machine, Portable Flux Welder with Digital Screen Display - YESWELDER True Color Solar Powered Auto Darkening Welding Helmet, Wide Shade 3.5/9-13 for TIG MIG ARC Grind Welding Hood Helmet - TOPDC Welding Gloves 14 Inches Fire/Heat Resistant Leather For Mig,Tig,Stick,Forge,BBQ,Grill, Fireplace,Wood Stove, Furnace,Pot,Oven --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/714607863-bestarc-145a-mig-welder-110v-220v-4-in-1-gas](https://www.desertcart.vn/products/714607863-bestarc-145a-mig-welder-110v-220v-4-in-1-gas) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-25*
