    • Compact and powerful!
Style: MIG145 110/220V
Review Image by Leslie Scruggs Leslie Scruggs
I received this unit as a Christmas gift. I have been hinting around at wanting a smaller portable welder that I can run off of my 8000 W generator, this powerful and portable unit checks all of the boxes. Right out of the box I installed the included flux wire And plugged into a dedicated 220 V outlet in my shop and ran some really nice beads on some quarter inch material with really good penetration and very little spatter. A neighbor needed some assistance with replacing a bent trailer jack and I was able to do the work on site running off of my 220 volt service from my generator using the flux wire and it turned out awesome I believe I was running about 135 A running my arc to the thicker trailer frame material. It fused the new jack to the trailer flawlessly. A quick cleanup with a wire brush and a few sprays of paint and it looks better than it did from the factory. I have a more expensive welder that does not weld as well as this lower priced unit welds I believe if it holds up, this will turn out to be a very good purchase. I am looking forward to using it with shielding gas once I get my tank refilled. ... show more

    • Seems just as good as their plasma cutters
Style: MIG145 110/220V
Review Image by MatteoV MatteoV
I purchased this 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. ... show more

    • I'm not a welder.....
I don't often review my purchases but this one is an exception. I got this welder on sale for under $100 and I was skeptical but all the good reviews gave me confidence. It's well packaged and overall quality and finish is very good. I am not a welder but I have done brazing and silver soldering over the years with a torch but I wanted to be able to weld steel parts. after unpacking and setting up the machine, I watched a few videos to try to glean some tips and then decided to give this a try. I set the machine in its auto mode which takes care of certain operations and tried my 1st weld. I had a piece of 3/16" steel and I just ran a few beads to see how the welder worked and I was totally surprised how easy it was to use. The beads came out very nice and I was impressed. Then I tried to weld a square tube to the plate. The tube thickness was much thinned and this is where welding skill pays off. It's easy to burn through the tube while trying to create a bead connecting the two pieces. I experimented with power setting and concentrated more on the thicker steel plate with OK results. The machine is great and I know over time I will get better at this but for my 1st experience with using it, I am more than pleased. It's a winner! ... show more

    • Bestarc budget welder!
Style: MIG145 110/220V
Just received one after Christmas and used it for Flux core only so far. Pretty small compact unit and I think a great little unit for beginners. Sure it has plastic housing for wire drive motor and a short 5’ whip for MiG gun but other than that, seems great for the price! I wish I didn’t have to purchase tig torch separately and just added it to the package as I would have paid up for it, but it is what it is! My only concern now is finding consumables! Hope to purchase the plasma cutter one day! ... show more

Great budget welder for diy projects.The MMA function is really good.The fluxcore was not working until i figured it out.The tip must be tightened and 0.004 selected on the machine.The manual has no troubleshooting information at all.For stick welding I would recommend stinger to positive and ground clamp to negative. ... show more

I read some bad reviews on it, I want you to ignore it, you just gotta know how to weld and every welder isn’t the same, this welder turned out great, i didnt have anything to really test it out on besides a bird feeder I made my daughter years ago when I first started welding and it had fell apart cause I didn’t penetrate my tacks due to me trying to make it a quick project. Couldn’t ask for a better welder and the deal I got on it through Amazon ... show more
