HIZONE 140A Simplified Aluminum MIG Welder, 6-in-1 Gas MIG/Gasless Flux Core MIG/Stick/Lift TIG Welding Machine with Large LCD Digital Display, 120V/240V Multiprocess Inverter Welder Machine

I got this welding system for my husband, though I didn't know a MIG from a TIG, I knew he would and would tell me I got him the WRONG kind of welding system. But here's the thing: the HIZONE 140A 6-in-1 MIG Welder is like the multitool of welders—perfect for anyone. Whether you need MIG, Stick, TIG, or even Aluminum welding, this welding system had me covered. What he loved: Super Versatile – Welds steel, aluminum, and more. Safety First – Built-in protections keep you from frying your welder (or yourself). What he didn't like so much: He said the wire feed can be a bit finicky. It also has no instructions to speak of, so it was trial and error. There needs to be more support either in printed instructions or on video in using this model. TIG mode is very difficult to set up without help. By and large, it's getting the job done--he does a lot of different projects in the garage. So, the bottom line on this: If you want one welder that does (almost) everything, the HIZONE 140A is a great pick, a great value for the money, a powerful took, functions fairly well, with a definite learning curve involved.

Attempting to feed the aluminum wire from the machine all the way through the line and through the gun makes the wire bunch up in the machine. After wasting a bunch of wire attempting to just get it out the gun, (which took me taking the gun apart, feeding the wire and assembling the gun) I was finally able to lay a beed on a scrap piece of Aluminum. However as soon as the arc flashed, the wire stopped and bunched up in the machine again. As you could imagine the heat created from how angry i was at this point nearly melted my scrap aluminum. I am a second chance kind of guy, and so I got a bottle of gas 75/25 and fed .030 wire through the line and welded steel fairly well, the feed is not real consistent, so for beginners this may not be the best learning machine. All in all I'd advise you to buy a better machine.

I had zero experience with welding, it was something I had always wanted to try. I felt a bit overwhelmed reading about all the different types of welds and techniques and decided to just get this and try it out. With this cheap unit, I wasn't too worried about ruining a (very) expensive tool and so its good to learn some basic technique. Now, I will say you're somewhat limited as to what you can do with this machine- flux core welding simplifies the process, but it is not suited for all metals, and the power of this machine effectively limits the size of the welds you can do. It is well suited for Aluminium, but it is NOT suited for cast iron, which unfortunately was what I wanted to ultimately make some repairs on. For my cast iron project (a fine crack in a radiator) I ultimately decided to repair with epoxy (JB weld) -- after consulting the JB weld company to ask for a product recommendation (they have MANY variants on their product, some for high heat, some that specifically say radiator...) the representative ultimately suggested I go with regular old original JB weld. Go figure. Even though a radiator is "hot" (200+f) its not "high heat (500+f") I chose to use the JB weld because everything I read indicated that cast iron is one of the most difficult metals to weld effectively, and doing so incorrectly can change the properties of the metal forming "white iron" which is then impossible to weld. As far as the machine goes, the controls are relatively intuitive and the form is un-intimidating-- not a professional, industrial looking machine. Again, for my use case, trying to learn the basics of welding and get some practice with technique, this was fine. Also a plus, you can just plug it into any old outlet. So its portable. For a handyman for something to take on jobs to make small repairs on site, this could be ideal.

plastic parts are very easy to brake

This welder is very easy to use and works well for gasless flux core MIG and stick welding. Its functionality is quite good, featuring a SYN that increases the voltage as the wire speed (amperage) is increased, making the setup process straightforward. This machine can also be used for solid wire welding with the addition of a gas regulator and a bottle of inert welding gas, which produces much cleaner welds. It is compatible with both 240V and 120V power sources, thanks to the included adapter. The duty cycle is 40% at maximum amperage: 140A at 240V and 110A at 120V. I successfully welded 10-gauge steel (approximately 3mm) using the supplied flux core wire without any issues. The welder appears to be well-made and offers good value. The display is bright and easy to read. I particularly enjoy using flux core for certain projects, especially when my stick welding skills are a bit rusty. Speaking of stick welding, it handled 6013 and 7018 electrodes up to 1/8 inch (on 240V) without problems. While I have only had this welder for less than a month, it seems very good in my opinion.
