When I started getting into welding, I was super confused about the terms: MIG, MMA, Flux-Core, gasless, etc. Let’s simplify one thing—Gasless MIG is also called Flux-Core MIG, and it’s different from traditional MIG that needs a gas tank.
If you’re building furniture at home, here’s what I learned after doing my own research:
What is Gasless MIG Welding?
Gasless MIG (Flux-Core MIG) uses a special wire that has flux built inside. When the wire melts, it creates a shield over the weld—so you don’t need a gas tank.
✅ Works even when it’s windy (no gas to blow away)
✅ Wire feeds automatically, so it’s easier for beginners
✅ Smoother welds than MMA
🚫 Not as clean as real MIG with gas
✅ Perfect for thin metal and DIY steel furniture
MMA (Stick) vs. Gasless MIG – Quick Comparison
| Feature | Stick Welding (MMA) | Gasless MIG |
|---|---|---|
| Ease of Use | Harder to start, rods can stick | Easier, just pull the trigger |
| Metal Thickness | Best for 3mm and thicker | Best for 1mm to 4mm |
| Weld Quality | Rougher welds, more spatter | Cleaner welds than Stick |
| Equipment Cost | Cheaper (₱3,500–₱5,500) | Pricier (₱7,000–₱12,000) |
| Portability | Very light & compact | A bit heavier, still portable |
| Outdoor Use | Great, even on rusty metal | Great, but works better on clean steel |
My Suggestion for DIY Projects
If you’re new and planning to weld steel tubes or angle bars for shelves, tables, or stands—Gasless MIG is the better option. It’s easier, cleaner, and faster to learn than MMA.
