When you're shopping for welding soldering equipment, these two 135A 110V 3-in-1 welders can look almost identical on paper. Both are IGBT inverter machines rated for 135A, both cover flux MIG, Lift TIG, and stick welding, and both offer synergic-style control that helps pair voltage and wire speed. The real difference is how each one balances portability, price, and the kind of protection you get while welding. Putting price and weight aside, the bigger question is where you weld most often: in a shop where the welder can stay plugged in, or outside where you need to carry the machine to the work.
Quick verdict
For most hobbyists, the HIZONE 135A MIG Welder is the better first buy. At USD 89.99, it costs USD 27.83 less than the AZZUNO and weighs less, so it's the easier choice to carry around. The AZZUNO is the shop-bound alternative: it costs more, weighs more, and is better suited to staying on a bench or cart.
AZZUNO vs HIZONE: key specs at a glance
| Feature | AZZUNO 135A MIG Welder | HIZONE 135A MIG Welder |
|---|---|---|
| Price | USD 117.82 | USD 89.99 |
| Max output | 135A | 135A |
| Input voltage | 110V | 110V |
| Welding processes | Flux MIG, Lift TIG, Stick | Flux MIG, Lift TIG, Stick |
| Plate rating | up to 3.0 mm | up to 5/32 in |
| Weight | 10.8 lb | 10.7 lb |
Where each wins
- HIZONE wins for mobile work. It's the lighter machine, has a shoulder strap for carrying, and its automatic feed matches voltage to wire speed. It also claims a slightly thicker plate rating, so it has a little more headroom for repair work on heavier stock.
- AZZUNO wins for a fixed workshop. The heavier chassis is no issue when the welder stays on a bench or cart, and the package is built around getting you set up quickly.
Product notes
#### AZZUNO 135A MIG Welder 110V 3 in1 Flux MIG/Lift TIG/Stick IGBT Welding Machine
The AZZUNO is the machine to keep on a workbench or cart. Its built-in overload and overheating system is the standout reason to choose it: if you're pushing the 135A output during longer practice runs, the protection is already part of the package. It accepts .030-inch and .035-inch flux core wire, and the MIG gun, electrode holder, and earth clamp come in the box, so you're ready for flux MIG and stick work. The trade-off is that it's the heavier and more expensive of the two, and the Lift TIG torch is not included, so you'll need an extra accessory for that mode.
#### HIZONE 135A MIG Welder Intelligent Portable IGBT Inverter 110V 3-in-1 Welding Machine
The HIZONE is the welder to grab when the work won't come to you, wherever the repair is. It weighs 10.7 lb and travels with a shoulder strap and handles, making it practical for outdoor repairs, farming, and road equipment maintenance. Its automatic feed matches voltage as you adjust wire speed, and the 10ft MIG torch, ground clamp, and electrode holder give you room to work around a vehicle. The one thing to keep in mind is that the Lift TIG mode requires an extra torch, so this isn't a fully self-contained TIG setup. If you mainly plan to run flux MIG and stick, this is a light and easy choice.
Final choice by use case
If you'll be moving the welder between jobs, choose the HIZONE. If you want a dedicated shop machine with overload and overheating protection during longer sessions, choose the AZZUNO. Most common repair jobs will fit both machines, so the deciding factor is whether you'd rather travel light or keep the welder on a bench.
