Overview
Performance: All-in-One Versatility
This is one of the most flexible machines on the market today. Whether you’re TIG welding aluminum, MIG welding steel, or plasma cutting through 12mm thick plate, the Rubik 200A delivers solid, dependable performance. The HF TIG arc starts cleanly, MIG and Stick modes offer stable output, and plasma cutting is efficient enough for both DIY and small-shop needs.
Power & Technology
Powered by IGBT inverter technology, the Rubik 200A maintains arc stability and consistent current across all modes. It easily adapts to 110V or 220V, making it perfect for both at-home and field operations. Even when switching between processes, there’s no notable lag or drop in arc performance—especially crucial when doing precise aluminum TIG welds or fast plasma cuts.
User Interface
The 7-inch LCD screen makes a world of difference. Every setting—from amperage and wire feed speed to switching between welding modes—is shown in real time. Beginners and pros alike will appreciate the intuitive interface, especially when jumping between different processes.
Safety
Overheat, overload, and short circuit protection features make this machine ideal for extended usage. The VRD (Voltage Reduction Device) ensures safety by reducing open-circuit voltage when idle, minimizing the risk of electrical shock.
Pros and Cons
| Pros | Cons |
|---|---|
| Extremely versatile – 7 processes in one machine | No foot pedal included for TIG |
| Dual voltage for flexible operation | Duty cycle not clearly specified |
| Powerful 12mm plasma cutting capability | Might be complex for absolute beginners |
| Lightweight and compact for portability | Lacks memory function for saved settings |
| Large, user-friendly LCD screen | Some plastic components may feel less rugged |
| Spool gun compatible (for aluminum MIG) | No dedicated up/down slope for TIG (advanced users) |
| Excellent safety system with VRD, overload protection | Limited brand recognition compared to big names |
What to Know Before Buying
Before pulling the trigger, here are a few key considerations:
Multifunction Master—But You Still Need to Learn
Yes, this machine does it all. But each welding process still has its learning curve. Don’t expect to TIG aluminum perfectly right out of the box unless you already have some experience. The machine can support it, but your technique will still matter.
No Foot Pedal
Unlike some TIG-specific machines, the Rubik 200A does not come with a foot pedal. If you’re used to that finer control, you may miss it.
Plasma Cutter Setup
The included air pressure regulator works well, but ensure your air compressor delivers clean, dry air at sufficient pressure to avoid consumable issues in plasma mode.
Best Features
Let’s zoom into the standout features that really make the RUBIK 200A shine.
1. 7-In-1 Process Capability
You’re not just buying a welder—you’re buying a complete metalworking station:
| Process | Typical Use |
|---|---|
| HF TIG | Precise aluminum/stainless steel work |
| Gas MIG | Clean steel fabrication with shielding |
| Flux Core MIG | Outdoor steel welding, no gas needed |
| Stick (MMA) | Heavy-duty and outdoor work |
| Plasma Cutting | Cuts steel up to 12mm |
| Spot Welding | Ideal for automotive panel work |
| SYN Function | Simplifies settings for beginners |
2. Intelligent Protection System
Overload? Overheat? Short circuit? The Rubik auto-detects all of it and adjusts or shuts down accordingly. Welders often push machines to the limit, so this is a huge plus for safety and longevity.
3. High-Performance Display
Most budget welders come with a basic LED or dial interface. The 7-inch LCD here gives you real-time control and monitoring over every process. A fantastic upgrade that improves accuracy and usability.
4. Portable Yet Powerful
At just 26.6 lbs, it’s easy to carry and store, even though it delivers serious amperage and cutting power.

FAQs
Can this machine weld aluminum with MIG?
Yes, it supports spool gun for aluminum MIG welding, provided you use the correct wire and shielding gas.
Is this welder beginner-friendly?
The SYN function and large display make it easier for beginners, but TIG and plasma modes still require learning.
What type of air compressor is needed for plasma cutting?
A compressor capable of delivering 60–90 PSI of dry, clean air is recommended for optimal plasma cutting results.
Can it be used on a standard household outlet?
Yes, it supports 110V input, making it compatible with most domestic outlets.
Does it support AC TIG for aluminum?
No, it supports DC TIG (HF Start) only. AC TIG for aluminum is not supported unless otherwise specified.
Final Thoughts
The RUBIK Multiprocess 200A 7-in-1 Welder Combo is a machine for anyone who wants maximum versatility without investing in multiple devices. Whether you’re a fabricator, auto repair technician, or home DIY enthusiast, this unit packs everything you need into one powerful, portable machine.
Its standout features—plasma cutting, HF TIG, Gas/Flux MIG, and a slick LCD interface—are almost unheard of at this price point. And while it has minor drawbacks like the absence of a foot pedal and unclear duty cycle, the overall value and functionality are hard to beat.
