The Weldpro gasless flux MIG welder has been an outstanding addition to my workshop. Right out of the box, it was easy to set up, and I was welding within minutes. The controls are straightforward, making it a great choice for beginners while still offering the performance that more experienced users will appreciate. The weld quality has been consistently impressive. It produces smooth, strong welds with excellent penetration, and the arc is stable and easy to control. I've used it on a variety of small fabrication and repair projects, and it has handled everything reliably. One of the biggest advantages is the gasless flux-core capability. Not having to deal with a shielding gas tank makes it much more convenient for outdoor work and quick jobs around the garage. The machine is also lightweight and portable, so it's easy to move wherever I need it. The overall build quality feels solid, and the included accessories were a nice bonus. For its size and price, this welder delivers performance well beyond my expectations. It has proven to be dependable, efficient, and simple to operate. If you're looking for a compact, reliable gasless MIG welder that offers excellent value and consistently produces quality welds, the Weldpro is a fantastic choice. I would definitely recommend it to anyone tackling home projects, automotive repairs, or light fabrication work.

I’m impressed. My history and mindset with welders has been around 300 amp Miller or Lincoln. I was dubious that a welder at this price, and weighing a bit more than a toaster could do anything. I used it to make several weld repairs on my camper trailer and add some frame crossmembers. It welded angle iron and flat metal up to 3/16” using the wire included. By the end of the project I’d burned nearly 4 pounds of wire. Out of position vertical and overhead worked well. The wire feed is smooth and consistent. It strikes easily. I tested my first welds with a sledgehammer and they held perfectly. Most of the time I ran it off my Honda 2200 generator. It runs wire of the generator just fine but I had to plug into a 20amp outlet to burn 3/32” 6013. I only burned a couple sticks of that for a test. This is a great little welder and made me update my thinking about welding machines.

Opened the box, loaded the flux wire, plugged it in, and welded some test pieces. This 5-in-1 Welder worked super! This replaced my burned-out Harbor Freight Titanium Flux 125 and is much better. I thought I was just an unskilled welder, but after only 30 minutes of playing around with this new unit, I was surprised. It was the machine, not me. Maybe better flux wire than HF, too. This 5-in-1 Welder comes with a wire welding gun, stick welding rod holder, and power cord adapter so you can run it from a 220 VAC outlet too. Wire welding has 2 modes. You can use it to TIG if you optionally buy a TIG Torch and Argon bottle. It will also spot-weld if you get yourself the correct tool head for the job. So far, I am very pleased.

The first welder arrived and didn't work. My wife and I disagreed about the cause. I said it didn't work because it would not feed wire. My wife said it wouldn't work because parts were falling out of it... An inductor fell out. Don't tell her, but she may have been more on point. In any case, we sent the first one back and got a second one thanks to Amazon return policy. I will assume the first one was dropped or poorly handled. Instead of a refund, I received a second unit. The second one works perfectly and I have tried multiple processes. My warning and 4-star is that there might be quality control issues leaving the factory. Maybe. Maybe it was bad handling. But, if you get one in good condition, then it does what is advertised and that is a whole lot of stuff. The extras they provide are laughable like the welding mask, but that is to be expected and I don't care as long as the welder itself does all the things this one says it does... and it appears to do...

I got this little guy for 100 bucks with a coupon for Amazon prime I didn’t really need it but I wanted something I could put in the truck and it gets it on at 120 V. Little bitty thing. So you can throw it in your toolbox and if you just need to glue something BOOM! It’s stuck Awesome machine. Oh the not gun is a total POS but if you’re like me, you’ve got about five guns sitting around so keep that in mind. And the grounding clamp is also a joke. So weldpro you get 31/2 out of 5
