RUBIKAluminum 250Amp MIG Welder - 5 in 1 MIG/Stick/Lift TIG Welder Gas Gasless Digital MIG Welder 110V/220V Dual Voltage LCD Display Welding Machine, Professionals Multi Process Welder

The media could not be loaded. I bought this machine as a pure novelty. I've worked with some of the best welding equipment available. Most of that equipment is in the multi-thousand dollar range.This is the second machine I purchased on that quest.Now I must qualify this review before I detail my experience. I have welded for more than 15 years, I know a good deal about welding and many of the variables that challenge the novice or beginner. Welding is a detail oriented task that can challenge the best of all of us at times.Setup of the machine is simple but yet complicated. For a novice there may be some frustration in understanding how to work this. It has many functions for welding, including that it is a high-current machine,This is useful for long welds but is not a feature found commonly on most small welders. Great to have if you know what you're doing though. You need to know what a good welding condition feels like to dial in any welder. For me on my project I was welding 3"x3" 1\4" thick angle iron doing mostly fillet welds and it took about a minute to get the gas, voltage and wire speed settings really close. The machine had a very stable arc and I was able to lay down a bead that was nearly text book perfect. I was shocked to be honest. I had my coworker try it as well, he laughed and said this thing welds better than the lincoln welder we have in our shop. While it will not match the thickness capabilities of that machine I believe the arc is better and more stable thanks to the inverter technology. For the beginner I can see this machine being frustrating at times. It's not as simple as a Miller or Everlast with pro set type functions. Pro set functions allow for fast acquisition of settings based on thickness of material to be welded and wire diameter with specific gas being used. For a novice it gets you in the ballpark of your initial setup faster. However those machines cost at least 5 times what this one does.Pros: Cost, lightweight, multivoltage, good stable arc, decent mig gun.Cons: tricky setup for the novice, also be careful with the drive roll knob, I dropped mine and it rolled inside the machine behind the drive motor side. I had to disassemble the front of the machine to get it back., no regulator ( not a deal breaker), ground clamp is pretty cheap the cable is adequate but do yourself a favor and spend $10 on a better one., lastly warranty not sure how long the warranty is but the gold standard is 5 years for top flight welding equipment I certainly don't expect that for the price point on this product.In summary it's a decent little welder if you need something cheap to do some garage repair type work I wouldn't hesitate to buy it. My goal in this little experiment was to test the capabilities of an inexpensive machine and I was able to produce similar results that I normally achieve with much pricier equipment.

I'll start off with the fact that I have zero experience with welding prior to purchasing the Rubik-135 but as we all know YouTube is a wealth of useful information and after going down the Welding rabbit hole I pulled the trigger and bought with my own dime this dandy little welding machine.After unboxing and inspecting the components they appear to be well made and durable, they include a roll of flux core wire , I purchased some blue demon welding rods to test the MMA function as well.After a half dozen uses I am overall impressed with the unit, my only complaint is that it does not include a Lift Tig gun in the kit but that would drive up the cost so that's a moot point , I do not regret my purchase, that is my opinion and it's worth what you paid for it.

Great welder. I only gave 4 stars because they don’t put a settings chart on the inside of the door like most welders have and the owners manual is pretty much useless. Would also be better if the wire speed was in the inches per minute instead of meters per minute. They also need to show the metal thickness recommended on the synergic control to make it more user friendly. But it welds outstanding for the price.

This little welder is amazing, works awesome way better then I expected

Welder arrived in a timely manner. All received well, except the protective lens for the face shield was broken. Rubik promptly upon notification issued a credit to more than cover the cost. Good Service!

Welder has tons of power and welds very well. I have thousands in miller welders and I bought this to keep under a bench to use there. DONT OVERTIGHTEN THE GAS FITTING. Use another wrench to hold the fitting while you tighten the gas hose or else you will snap off the fitting from the gas valve.

The machine itself seems to work really well. The knobs, display the wire feeder, they all work well. For $100 (3/2025) it feels like a bargain. I wish I can say more about it but I'm still very much learning. I picked this up because I have big ideas that require welding and those welds don't need to look very good. I can't fault the machine so I will leave that to others.
